Function to inverse function f(x) =2x/3-17

ZanzabumX [31]

Answer:

Inverse function is $f^{-1}(x)=\frac{3}{2}x+\frac{51}{2}$ .

Step-by-step explanation:

Given function is $f\left(x\right)=\frac{2}{3}x-17$ .

Now we need to find the inverse of the given function.

Step 1: replace f(x) with y

$y=\frac{2}{3}x-17$

Step 2: switch x and y

$x=\frac{2}{3}y-17$

Step 3: solve for y

$x=\frac{2}{3}y-17$

$x+17=\frac{2}{3}y$

$\frac{3}{2}(x+17)=y$

$\frac{3}{2}x+\frac{51}{2}=y$

Hence required inverse function is $f^{-1}(x)=\frac{3}{2}x+\frac{51}{2}$ .

What is the image of point (2,4) under<br> the<br> translation T-6,1?

maria [59]

I’ve never done this before but..
(2,4)
we translate x down -6 which would be -4.
we translate y up 1 which would be 5.
so i’m thinking the answer would be (-4,5)

Willis bought a gallon of paint. He painted a wall that is 9 feet high and 10 feet wide. Then

ankoles [38]

The andwer would be 136 beause you would have to multiply 9 and 10 to get its area in square feet, then you would have to add the answer to that problem(90) to 46 square feet, and your answer would be 136

I don’t have time for a specific answer right now but basically it would be in the same spot except flipped so it’s on the right now.
