If f(x) = 4x² -3 and g(x) = x+1, find (f - g)(x)
Answers
The value of (f - g)(x) = 4x² - x - 4.
Function - A function is a relationship or expression involving one or more variables. It has a set of input and outputs. Each input has only one output. The function is the description of how the inputs relate to the output.
We have been given that -
f(x) = 4x² - 3
g(x) = x + 1
Find out (f - g)(x) = ?
(f - g)(x) = 4x² - 3 - (x + 1)
(f - g)(x) = 4x² - 3 - x - 1
Output of
(f - g)(x) = 4x² - x - 4
Hence , for the given function f(x) = 4x² - 3 and g(x) = x + 1 the relationship of (f - g)(x) is 4x² - x - 4.

Unknown Numbers
Consider the following problem.
One number is 3 less than 6 times a second number.
Their sum is 46. Find the numbers
If × represents the second number, which equation is
correct for solving this problem?
Answers
Step-by-step explanation:
y is the second number. This means we can define it as the following equations where x is the second number:
y=6x-3
y+x=46
we have a system of equations, let's move all x to the right side
y=6x-3
y=46-x
this means that 6x-3=46-x
6x+x=46+3
7x=49
x=7
now that we know x we can calculate the y through one of the equations above:
y=39
Use the inverse of the coefficient matrix to solve the system of equations.
x+2y+3z = 11
2x+3y+4z = -10
−x−4y−8z = −66
Answers
Answer:
(x, y, z) = (-62, 50, -9)
Step-by-step explanation:
You want the solution to this system of equations using the inverse of the coefficient matrix.
x+2y+3z = 11
2x+3y+4z = -10
−x−4y−8z = −66
Inverse matrixThe inverse of the coefficient matrix is the transpose of the cofactor matrix, divided by the determinant. There are some shortcuts that can be used to make the computation easier. Easiest is letting a calculator find the matrix inverse. (See the first attachment.)
SolutionThe solution to the set of equations is the product of the inverse matrix and the constant vector on the right of the equal signs. That, too, can be found using a calculator. (See the second attachment.)
The solution is (x, y, z) = (-62, 50, -9).

How to find angles formed by parallel lines?Parallel lines are those lines that are equidistant from each other and never meet.
Parallel lines cut by a transversal, forms different angle relationship like alternate angles, corresponding angles, etc.
The line a and m are parallel lines.
The parallel lines are cut by a transversal y.
The angles formed are 1, 2, 3, 4, 5, 6, 7, 127 degrees etc.
This angles are related by alternate rule or corresponding rule.
Therefore,
∠3 is an alternate angle to 127 degrees.
Hence, alternate angles are congruent.

Assuming that the line segments CE and FH are parallel, then:Angle W
Here we have Opposite Angles by Vertex, so
W = 14
According to the attached figure, the angle W is also corresponding, so in the triangle CEG one of the angles will be 14°
Angle Z
The sum of the interior angles of a triangle is 180°, so for triangle CEG:
Z + W + 78 = 180
Z + 14 + 78 = 180
Z = 88
Angle X
Z and 4X are complementary angles, then
Z + 4X = 180
88 + 4X = 180

Can you use absolute value when subtracting two negatives?
- 2 1/2 - (-1 2/3)
or does it only work when one number is negative?
Answers
Yes, it is possible to use absolute value when subtracting two negatives and as such it does not only work when one number is negative.
How to Interpret Absolute Values?
When adding two negative numbers, add the absolute value of the numbers and keep the negative sign.
For example -1 + -2 = - (||-1| + |-2||), which is -(1 + 2) or -3
The absolute value when subtracting two negatives is -2¹/₂ - (-1²/₃) is possible because when subtracting, we will change the subtraction to addition and change the sign of the number being taken away.
Thus, we can conclude that it is possible to use absolute value when subtracting two negatives.

The solution for the equation 7x-4 = -18 is x = -2
The equation given is, 7x - 4 = -18.
We will try to solve this equation using elimination method in the following steps.
7x-4= -18
⇒ 7x-4+4 = -18+4
⇒7x = -14
⇒7x/7 = -14/7
⇒x = -2 is the solution for the given equation.
In the first step, we added 4 on both sides to eliminate -4 on the left side.
In the next step, we divided the both sides by 7 to eliminate the 7 on the left side. Finally, we got the solution as x = -2.

There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.let x be the salary of individual with bachelor degree
Then the average salary of individual with Masters degree is:
(2x-40000)
the combined of two salaries is 130000:
x+(2x-40000)=130000
3x-40000=130000
3x=130000+40000
x=170000/3
x = 56,666.66
x= 56,666.6 dollars ( the average salary of bachelor degree)
the average salary of Masters degree = 2x - 40000

What do we mean by speed?The definition of speed is The rate at which an object's position changes in any direction. Speed is defined as the ratio of distance traveled to time spent traveling. Because it has only one direction and no magnitude, speed is a scalar quantity.So, let's assume that y70m/s is the terminal velocity.
As 1 meter = 3.3 feetThen, 70 meters = 70 × 3.3 = 231 ft/secParachutist will fall at what rate in 2 seconds: 462 ft/secTherefore, the rate of feet per second is 231 ft/sec and parachutists will fall 462 ft in 2 seconds.
