Answer:

x=30

Step-by-step explanation:

The two angles are supplementary.  They add to 180

4x+20 + 40 =180

Combine like terms

4x+60 =180

Subtract 60 from each side

4x+60-60 = 180-60

4x = 120

Divide each side by 4

4x/4 = 120/4

x = 30

Given f(x) = the quantity of x plus 7, divided by 5, solve for f−1(3)
Debora [2.8K]
<span>f(x) = the quantity of x plus 7, divided by 5f(x)= \frac{x+7}{5}


</span>

To get the inverse of any function f(x) [ just make sure that it passes the horizontal line test] follow the steps:

- Solve for x, i.e separate x in one side and the other terms in the other side, included f(x).

- Swap x and f(x).

- The result is the inverse of the original function f^{-1}(x)



So that:

5*f(x)=x+7\\~\\~\\5f(x)-7=x\\~\\~\\Swap~now\\~\\~\\f^{-1}(x)=5x-7



and for the value of 3:

f^{-1}(3)=5(3)-7=15-7=8


I hope that helps!
