Answer:
A) x = m - n - p
Step-by-step explanation:
m - x = n + p
subtract m from both sides
m - x (- m) = n + p (- m)
m cancels out on the left and stays on the right
- x = n + p - m
divide by -1 because this is the constant in front of x
visualize as -1*x if it helps (anything multiplied by 1 is that number)
(- x / -1) = (n / -1) + (p/ -1) - (m/ -1)
the positives become negative and the negatives become positive
x = -n - p + m or x = m - n - p

No: g(x) of not the inverse function of f(x)
Given data
f(x) = -4 ( -2x + 9 )^3 - 8
g(x) = - cube root ( -5x + 6 ) + 2
How to find the inverse function of f(x)f(x) = -4 ( -2x + 9 )^3 - 8
dividing through by - 4 gives
= ( -4 ( -2x + 9 )^3 ) / -4 - ( 8 / -4)
= ( -2x + 9 )^3 - ( -2 )
= ( -2x + 9 )^3 + 2
finding the cube root

= cube root ( ( -2x + 9 )^3 + 2 )
= ( -2x + 9 ) + cube root ( 2 )
( -2x + 9 ) + cube root ( 2 ) ≠ g(x) = - cube root ( -5x + 6 ) + 2

Find the following given the function f(x)=
Answer:
The function f defined by the formula f(x) = 2x +1 can be expressed as: f(4) = 9; f(-5) = - 9, f(0) = 1,
The function of a function defines and explains the relationship between two different variables. From the given information, we are meant to replace x with the following given options and solve for the value of x.
f(4) = 2(4) + 1
f(4) = 8 + 1
f(4) = 9
f(-5) = 2(-5) + 1
f(-5) = -10 + 1
f(-5) = - 9
f(0) = 2(0) + 1
f(0) = 0 + 1
f(0) = 1
Step-by-step explanation:
Basically first you have to check what the f(x) fits into what category.
The picture shows different equations based on what the f(x) is.
In this case, f(x) is 7. So first check is 7 greater than 5, YES. But check with the next one too. Is 7 less than or equal to 5, NOPE

Suppose that a company has just purchased a new computer for $2400. The company chooses to
depreciate using the straight-line method for 3 years.
(a) Write a linear function that expresses the book value of the computer as a function of its age.
V(x)
The linear function is V(x) = 800x + 2400.
Given,
The cost of computer when purchased (the initial book value), V = 2400 (x = 0)
Company chooses to depreciate for 3 years using straight line method.
The book value after 3 years = 0 (x = 3)
We have to write a linear function that expresses the book value of the computer as a function of its age V(x).
Here, the value is depreciating over 3 years.
That is 2400 in 3 years = 2400/3 = 800
That is depreciating $800 in a year.
Now we can write the equation as:
V(x) = 800x + 2400

The line passing through the origin and parallel to the line passing through the points (8, 3) and (10, 8).
The equation of a line passing through the origin and parallel to the line passing through the points (8, 3) and (10, 8) is 2y - 5x = 0.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
Let's suppose the equation of that line as the slope-intercept form is
y = mx + c
Where m is the slope while c is the y-intercept.
Now this line is parallel to a line that passes through points (8, 3) and
(10, 8) thus meaning the slope of both lines must be the same.
So,
Slope associated with points (8, 3) and (10, 8) ⇒
m = difference in y's coordinate / difference in x's coordinate
m = (8 - 3)/(10 - 3)
m = 5/7
So our equation will be y = (5/7)x + c
Since it is passing through the origin or (0,0) so it will satisfy the coordinate.
Therefore,
0 = (5/7)0 + c ⇒ c = 0
It means y = (5/7)x ⇒ 7y - 5x = 0 will be the equation.
Hence "The equation of a line passing through the origin and parallel to the line passing through the points (8, 3) and (10, 8) is 2y - 5x = 0".

A. (-5,1)
B.(5,-3)
C.(5,1)
D.(-5,-3)
===========================================================
Explanation:
The preimage (-6,-2) shifts to the image point (-4,-4)
Focus on the x coordinates. The jump from -6 to -4 is an increase of 2. So we have x become x+2
Now focus on the y coordinates. The jump from -2 to -4 is -2, so y becomes y-2
The translation rule we use is [tex](\text{x},\text{y})\to (\text{x}+2,\text{y}-2)[/tex] which shifts the point 2 units to the right and 2 units down.
-----------------
Let's apply this rule to the point (3,-1)

Dividing both sides by 18, we have:

Mean weight = 2.7 grams
Standard deviation = 0.1 gram.
Fitness center
Mean weight = 100.2 pounds
Standard deviation = 0.1 pound
In the above parameters, we can see that the fitness center has a larger mean weight than the last shipment, while they both have the same standard deviation
This means that the standard deviation of the fitness center is larger than the standard deviation of the last shipment
