Answer:
The inverse is 
(x) = 
Step-by-step explanation:
(By the way, (x) is f negative one of x, like f(x), but inverse)
f(x) = 
- 4 is the same as y = - 4
y = - 4 start with the equation.
x = 
- 4 switch x and y.
x + 4 = add 4 to both sides.
= y square both sides.
(x) = change y to the inverse f(x) format.

The answer is B.
You will get 7.40 mean (original 4.44) with the 12th item and 4.99 (orginal 4.79).
The mean increase by about $3 while median only increased by 20 cents.
16) you are right
3x-4=2x+6
x=10
17)
1st segment = x
2nd segment = 2x
3d segment = 4x+3
equation x+2x+4x+3=38
7x = 38-3
7x=35
x=5
First segemnt = 5 inch
2nd segment 2x = 2*5 = 10 inch
3d segemnt 4x+3=4*5+3=23 inch
Answer:
