explain how to graph the equation on a coordinate plane: y = 3x - 5
lations below are also functions?
To graph an equation on the co-ordinate plane we plot points that satisfy the given equation .
The graph of a linear equation is two variables gives a straight line on the co-ordinate plane.
To graph a straight line on the co-ordinate plane we take three points or solution of the equation on the line and join them.To calculate the solutions(points) of the line we take some values of x and calculate the corresponding values of y.Then we make a table of the points and graph the equation of the line by joining the points.the given equation is y=3x-5
at x=0 ,y=3×0-5 or y=-5
at x=2 , y=(3×2)-5 or y=1
at x=-1,y=(3×-1)-5 or y=-8
Now we make the table to get the desired points.
x y point

Factor out the greatest common factor.
4x³+16x² +8x
The greatest common factor for 4x³+16x² +8x is 4x(x2- 4x - 2).
This solution focuses on simplification:
4x(x2-4x-2)
(4(x3)-24x2)-8x
(22x3-24x2) -8x
Take similar factors aside:
4x3-16x2-8= 4x(x2-4x-2)
Factoring x2 - 4x - 2
x2 is the initial term, and it has a coefficient of 1.
The coefficient of the intermediate term, which would be -4x, is 4.
"The constant," the final term, is -2.
Multiply the constant by the coefficient of the first term. 1 -2 = -2
The second step is to find two -2 factors whose sum is equal to the -4 coefficient of the middle word.
-2 + 1 = -1
-1 + 2 = 1
No two of these factors can be discovered!!
Trinomial cannot be factored.
Hence, The greatest common factor is 4x(x2- 4x - 2).

Calculate the magnitude of the repulsive force between a +500μC charge and a +100μC charge which are 5 m apart. [k=9×109 Nm2C-1]
The magnitude of the repulsive force between a +500μC charge and a +100μC charge which are 5 m apart is 2N.
The repulsive force between two charges = (k q₁ q₂)/r²
q₁ q₂ are the charges
r is distance between the charges
k= 9×10⁹ Nm²C²
F= (500μC) (+100μC)9×10⁹/25
= 2N
A movement between two charges that are same or comparable is referred to as repulsion. The tension between two electrons (negative charge). Two charges of a different sort are drawn toward one another by the force of attraction, which is defined as "a force between two charges that are distinct or different."
At a distance, magnetism is an attractive or repulsive force. The repulsive force gives rise to a metric that measures how a system's gravitational mass changes. According to the force-based approach, the forces that attract and repel other atoms come from their subatomic arrangement and control how they behave.

O 70 square units
O 120 square units
The area of the given figure is 70 square units, that is, option 3.
The area of a rectangle = length × breadth
Here, we need to find the area of the shaded region.
To do this, we will subtract the area of the smaller rectangle from the larger one.
The area of the larger rectangle = 8 × 15
= 120 square units
Now, the we have one side of the smaller rectangle which is 5, the other side will be (15 - 4 - 1) = 10 units.
The area of the smaller rectangle = 10 × 5

Thus, the area of the shaded region = 120 - 50

Use the slope formula to find the slope
The slope of line: 1. m= 6 , 2. m= -6 , 3. m= 2.5, 4. m= .5
The slope of the line :
In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.
The net change in the y-coordinate is represented by Δy and the net change in the x-coordinate is represented by Δx.
Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,
m = change in y/change in x = Δy/Δx
Where “m” is the slope of a line.
Tan θ = Δy/Δx can also represent the slope of the line
So, tan θ to be the slope of a line.
Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The letter ‘ m’ usually represents the slope.
If P(x1,y1) and Q(x2,y2) are the two points on a straight line, then the slope formula is given by:
Slope,
m = Change in y-coordinates/Change in x-coordinates
m = (y2 – y1)/(x2 – x1)
Therefore, based on the above formula, we can easily calculate the slope of a line between two points.
In other terms, the slope of a line between two points is also said to be the rise of the line from one point to another (along the y-axis) over the run (along the x-axis). Therefore,
Slope, m = Rise/Run
1.
(-1,-1) & (0,5)
m = (y2 – y1)/(x2 – x1)
m = (5 – (-1)) /(0– (-1))
m = (5 +1)/(0 +1)
m = (6)/(1)
m = 6
2.
(3,5) & (4,-1)
m = (-1 – 5)/(4 – 3)
m = (-6)/(1)
m = -6
3.
(2,1) & (4,6)
m = (6 – 1)/(4 – 2)
m = (5)/(2)
m = 2.5
4.
(-5,-2) & (3,2)
m = (2 – (-2))/(3 – (-5))
m = (2 +2/(3 +5)
m = (4)/(8)
m = (2/(4)
m = (1)/(2)
m = 0.5

A passenger in an airplane at an altitude of 10 kilometers sees two towns directly to the east of the plane. The angles of depression to the towns are 24° and 53° (see figure). How far (in km) apart are the towns? (Round your answer to one decimal place.)
Using relations in a right triangle, it is found that the distance between the towns is of 15 km.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.For the first town, we have that:
The internal angle of the triangle 90 - 53 = 37º.The opposite side to the angle is the horizontal position xA.The adjacent side to the angle is of 10 km.Hence:
tan(37º) = xA/10
xA = 10 x tan(37º).
xA = 7.5 km.
For the second town, we have that:
The internal angle of the triangle 90 - 24 = 66º.The opposite side to the angle is the horizontal position xB.The adjacent side to the angle is of 10 km.Hence:
tan(66º) = xB/10
xB = 10 x tan(66º).
xB = 22.5 km.
Hence the distance is:
22.5 km - 7.5 km = 15 km.

a) James have to invest 5,248 dollar and 89 cent to earn $7,592 amount of interest in 16 years .
b) Principal amount of money , which is to be invested is 4158 dollar and 46 cent .
This is a problem from simple interest system. We have to use the given formula, I = p.r.t to solve this problem.
a) James wants to have earned $7,592 amount of interest in 16 years. So, here the time period is 16 years and the interest rate is 9.04% and we have to find the principal amount.
I = p. 16. ( 9.04% )
Amount of interest = $ 7592
Time period = 16 years
rate of interest = 9.04 %
7592 = p . 16 . ( 904/10000 )
p = 75920000/ 16 . 904
or , p = $5,248.89 ≈ $5249
James have to invest $5,248.89 to earn $7,592 amount of interest in 16 years .
b) We have to use the given formula to find the value of p or the principal amount of money .
Rate of interest = 8.63% or .0863
time period = 24 years
Interest = $8613

For the rational function f(x)=2−x4x+6, find the point on the graph at the function value f(x)=1.
The point on the graph at the function value f(x)=1 is x = -4/5
How to find the point on the graph at the function value f(x)=1?The equation of the function is given as:
f(x) = 2 - x4x + 6
Rewrite the rational function, properly as follows:
f(x) = 2 - x/4x + 6
When f(x) = 1, we have:

You can just solve for x which goes as follows:
6 * 1/6 = 6 * 16 - Multiply both sides by 6.
x = 96
Answer:
x=96
Step-by-step explanation:
To figure out the weight of the person on the moon we would need to take their weight and divide by 6. we don't know the weight so it's x. We know the final weight so the x divided by 6 should be 16.
