Answer:

$f^{-1}(x)=25(x-2)^2$

Step-by-step explanation:

The inverse function can be found by solving ...

f(y) = x

(√y)/5 +2 = x

(√y)/5 = x -2 . . . . . subtract 2

√y = 5(x -2) . . . . . . multiply by 5

y = 25(x -2)² . . . . . square both sides

The inverse function is ...

$f^{-1}(x)=25(x-2)^2$

Find X. 2x + 15 = 20

lakkis [162]

Answer:

x = 5/2 or x = 2.5

Step-by-step explanation:

To solve for x, we will have to get the equation 2x + 15 = 20 into the form x = _. That will be our answer.

2x + 15 = 20

Subtract 15 from both sides to get rid of the +15 on the left side.

2x = 20 - 15

Simplify.

2x = 5

Divide both sides by 2 to get rid of the coefficient of 2 on the left side.\

x = 5/2 = 2.5

x = 5/2 or x = 2.5

I hope you find my answer helpful. :)
