The equation for the linear function is y=3x -5.
Linear FunctionA linear function can be represented by a linear equation. The standard form for the linear equation is: y= mx+b , for example, y=10x+6.
The standard for the linear equation( y= mx+b), also it is known as the Slope-Intercept Form.
Where:
m= the slope.
b= the constant term that represents the y-intercept.

From the given data you can find the slope by solving the system linear equation.
For example, you can write a system linear equation from the points: (1,-2) and (4,7).
-2=m+b (1)
7=4m+b (2)
Multiplying equation 1 by -1, you have
2= -m -b (1)
7= 4m+b (2)
Summing the previous equation, you can find the slope (m):
9=3m
m= 9/3
m= 3
If m=3, from equation 2, you can find the coefficient b.
7 = 4m + b
7 = 4*3 +b
7=12 + b
b= 7-12
b= -5
Thus, the standard form for the linear equation represented by the given table is y=3x -5.

The difference between the water levels for high and low tide was 3. 6 feet. Write and solve an equation to find the water level at high tide
Answers
The difference between the water levels for the high and low tide was 3. 6 feet. the equation to find the water level at high tide x = y + 3.6, where High Tide Water Level = x and Low Tide Water Level = y.
In simple form it will be High Tide Water Level = Low Tide Water Level + 3.6. To explain this equation, the water level at high tide is equal to the water level at low tide plus 3.6 feet. The variable 'x' represents the water level at high tide, while the variable 'y' represents the water level at low tide. By adding 3.6 feet to the water level at low tide, we can find the water level at high tide.
For example, if the water level at low tide is 4 feet, the water level at high tide would be 4 + 3.6 = 7.6 feet. To find the water level at high tide for any given low tide water level, one can simply add 3.6 feet to the known low tide water level. This equation can be used to accurately calculate the water level at high tide for any given low tide water level.

A ball is thrown upward at an angle of elevation of 28 degrees with a force of 19n. How much of that force is horizontal and how much of that force is vertical?
Answers
19N force act in upward direction with angle of elevation 28 degrees has horizontal and vertical force is given by 16.78N and 8.92N respectively.
Angle of elevation while thrown a ball upward 'α' = 28 degrees
Force 'F' is equal to 19N.
While throwing a ball force is applied in two possible direction are:
Horizontal direction and Vertical direction.
For horizontal direction :
let 'x' represents the horizontal direction
cosα = x / F
⇒ cos28° = x / 19
⇒ x = 19 cos 28°
⇒ x = 19 × 0.8829
⇒ x = 16.78N
For Vertical direction :
let 'y' represents the vertical direction
sinα = x / F
⇒ sin28° = y / 19
⇒ y = 19 sin 28°
⇒y = 19 × 0.4695
⇒ y = 8.92N
Therefore, the horizontal force and vertical force for the given angle of elevation is equal to 16.78N and 8.92N respectively.

If D > 0 and not an excellent square, then the roots of the quadratic equation are real, unequal and irrational.
What is Quadratic Equation ?
Quadratic equation can be defined as equation in which it is in the form of ax^2+bx+c = 0 .
Nature of Roots depending upon Discriminant
in step with the value of discriminant, we shall discuss the subsequent cases about the character of roots.
Case 1: D = 0
If the discriminant is same to 0 (b2 – 4ac = zero), a, b, c are real numbers, a≠0, then the roots of the quadratic equation ax2 + bx + c = zero, are real and equal. In this case, the roots are x = -b/2a. The graph of the equation touches the X axis at a single point.
Case 2: D > 0
If the discriminant is greater than zero (b2 – 4ac > 0), a, b, c are actual numbers, a≠0, then the roots of the quadratic equation ax2 + bx + c = 0, are actual and unequal. The graph of the equation touches the X-axis at two unique points.
Case 3: D < 0
If the discriminant is less than 0 (b2 – 4ac < 0), a, b, c are real numbers, a≠0, then the roots of the quadratic equation ax2 + bx + c = 0, are imaginary and unequal. The roots exist in conjugate pairs. The graph of the equation does not touch the X-axis.
Case 4: D > zero and perfect square
If D > zero and an excellent square, then the roots of the quadratic equation are actual, unequal and rational.
Case five: D > 0 and now not an excellent square
If D > 0 and not an excellent square, then the roots of the quadratic equation are real, unequal and irrational.
Therefore, If D > 0 and not an excellent square, then the roots of the quadratic equation are real, unequal and irrational.

the diagonals of a trapezoid are perpendicular and have lengths $3$ and $4$. find the length of the median of the trapezoid.
Answers
The correct answer is 5/2. The median trapezoid is the line segment that bisects the area of the trapezoid and has its end points on the 2 bases of the trapezoid.
The median length is √( (3/2)^2 + (4/2)^2 ) = √(9/4 + 16/4) = √(25/4) = 5/2. So, the length of the median of the trapezoid is 5/2.
Since the diagonals of a median trapezoid bisect each other, the median of the trapezoid is the line segment that connects the midpoints of the diagonals. To find the median length, we can use the distance formula, which is the square root of the sum of the squares of the differences in the x-coordinates and y-coordinates of the 2 points. In this case, the median length is the square root of the sum of the squares of 1/2 length of the diagonals.

The price of a new car was $22,800 in April. However, the price of the car was reduced by 5% in May. Find the price in May.
In May, the price of the car was ? % as compared to
the price of the car in April.
Answers
Answer: To find the price of the car in May, we can use the formula:
New price = Original price - (Original price x Discount rate)
In this case, the original price is $22,800, and the discount rate is 5%, which can be written as 0.05.
So, the new price in May is:
New price = 22700 - (22700 x 0.05)
New price = 22700 - 1135
New price = $21,565
So, the price of the car in May was $21,565.
To find the percentage of the price of the car in May as compared to the price of the car in April, we can use the formula:
(New price / Original price) x 100
In this case, the new price is $21,565 and the original price is $22,800
(21565 / 22700) x 100 = 0.95 x 100 = 95%
Therefore, in May, the price of the car was 95% as compared to the price of the car in April.

Answers
Lisa and Joe put $46 towards the gift
How much money did Lisa and Joe put towards the gift?Let's call the amount of money that Sara put in "x".
Joe put in twice that amount, so he put in 2x.
Lisa put in ten dollars more than Sara, so she put in x + 10.
Together, Sara, Joe, and Lisa put in x + 2x + (x + 10) = $58.
Evaluate the like terms, so we have
4x + 10 = 58.
Subtracting 10 from both sides, we get
4x = 48.
Dividing both sides by 4, we find that
x = $12.
So Sara put in $12, Joe put in $24, and Lisa put in $22.

Find the 67th term of the arithmetic sequence -17,-23,-29
Answers
The 67th term of the arithmetic sequence -17,-23,-29 is -413.
What is the arithmetic sequence?
An arithmetic sequence is a sequence of numbers such that the difference between any two consecutive terms is always the same. This difference is called the common difference, and it can be represented by the variable d.
Given the sequence -17,-23,-29, we can see that the common difference is d = -23 - (-17) = -6
The nth term of an arithmetic sequence can be found using the formula:
a_n = a_1 + (n-1)d
where a_1 is the first term of the sequence, n is the term number and d is a common difference.
For the 67th term, a_1 = -17, n = 67 and d = -6
So the 67th term is:
a_67 = -17 + (67-1) * -6 = -17 + 66 * -6 = -17 - 396 = -413
Hence, the 67th term of the arithmetic sequence -17,-23,-29 is -413.

Answers
A certain corner of a room is selected as the origin of a rectangular coordinate system. A fly has coordinate (1.7, 0.6). The distance of the fly from the corner of the room is 1.8 meters.
Suppose we have a point having coordinate (x,y). Then the horizontal axes, vertical axis, and the distance from the origin form a right triangle which its base is x and y.
Hence, we can find the distance of the point (x,y) from the origin using the Pythagorean Theorem.
In this case, the origin is a certain corner of the room. The coordinate of the fly is (1.7, 0.6) meters.
Using the Pythagorean Theorem:
distance = sqrt (1.7² + 0.6²)
distance = sqrt (2.89 + 0.36)

According to the elimination method, the solution of the system of equation has infinite number of solutions.
In math the term elimination method is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables
Here we know that the equations are
=> 6x - 2y = 8 ---------------(1)
=> -3x + y = -4 ------------------(2)
when we simplify the equation (1) by dividing the terms by 2, then we get
=> 3x - y = 4
Now, we have to add the two equation then we get the result as,
=> (-3x + 3x) +( -y + y) = (-4 + 4)
=> 0 + 0 = 0
Hence the system has an infinite number of solutions.

Answers
Answer:
D. 0.391
Step-by-step explanation:
You want the approximate solution to f(x) = x² -3x +1 = 0 on the interval [0, 1] using 5 iterations of the Bisection Method.
IterationThe Bisection Method makes one iteration by finding the function value at the midpoint of the interval. The midpoint replaces the end of the interval whose function value has the same sign. At the end of one iteration, the midpoint of the halved interval is calculated.
Start:
f(0) = 1, f(1) = -1. Interval: [0, 1]; midpoint: 1/2
First iteration:
f(1/2) < 0. Interval: [0, 1/2]; midpoint: 1/4
Second iteration:
f(1/4) > 0. Interval: [1/4, 1/2]; midpoint: 3/8
Third iteration:
f(3/8) > 0. Interval: [3/8, 1/2]; midpoint: 7/16
Fourth iteration:
f(7/16) < 0. Interval: [3/8, 7/16]; midpoint: 13/32
Fifth iteration:
f(13/32) < 0. Interval: [3/8, 13/32]; midpoint: 25/64
SolutionThe approximate solution after 5 iterations is x ≈ 25/64 ≈ 0.391.

Additional comments
The approximate solution in the interval to full calculator precision is 0.38196601125. The exact solution is 1.5-√1.25.
You will notice that the function values for the ends of the interval [0, 1] are [positive, negative]. So, when the function value at the midpoint is negative, that point replaces the right end of the interval.
Of course, the midpoint is the average of the interval end values.
On average, it takes about 3.3 iterations to improve the accuracy of the solution by 1 decimal place.

What are expressions?
Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.
e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.

Sara says if you subtract 19 from my number and multiply the difference by -6 the result is -96,
what is saras number
PLEASE PLAE PLASE PALSE PLASEP APLSASEP PLASEP PLEASE PLAESESEEPZ.
Answers
Step by step
Your number is n
Subtract 19 from your number
= n - 19
Multiply the difference by -6
= -6(n - 19)
The result is -96
So your equation is
-6( n - 19) = -96
divide both sides by -6 to isolate n
-6/-6 (n - 19) = -96 / -6
n - 19 = 16
Add 19 to both sides to solve for n
n - 19 + 19 = 16 + 19
Simplify
n = 35
Your number is 35
Check your work
Your equation is -6( n - 19) = -96
Sub in 35 for n
-6( 35 - 19) = -96
Divide both sides by -6
35 - 19 = 16
16 = 16
It equals so your solution is correct!
Function rule or explanation of why it is not possible to find a function rule

b. Function
c. Not a function
d. Function
It’s easy to tell if a graph or a data table is a function or not. For a graph, use the vertical line test. Simple draw or imagine a vertical line straight down from the top to the bottom of the graph. The vertical line can only touch the line on the graph once, anything more than once will fail it as a function. So like circles will fail the vertical line test, and therefore, is not a function. You also have to go through the whole graph, left to right, with the vertical line test.
For data tables, look out for x values. In one table, the same x value cannot happen more than once. If you see two same x values, it is not a function, if not, it is. So as you see in the third one, there are duplicates of -100, -25, and -4. Whereas in others, there are no duplicate x values.
