If f(x)=2x/7+4, which of the following is the inverse of f(x)?

f(x) = 2x/(7 + 4)

Replace f(x) with y

y = 2x/(7 + 4)

Switch x and y

x = 2y/(7 + 4)

Solve for y

Simplify first

x = 2y/11

* 11

11x = 2y

/2

5.5x = y

Turn y into f^-1(x)

f^-1(x) = 5.5x

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
