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!

HURRY! What value of m completed the two-way table?
vlabodo [156]
<h3>Answer:  13</h3>

=========================================================

Explanation:

We're told that there are 50 people in each grade that are surveyed. So that means 50 eighth graders were surveyed.

Add up the values along the bottom row. Set the sum equal to 50 and solve for m

m+8+29 = 50

m+37 = 50

m = 50-37

m = 13

Then note how 13+8+29 = 50 along the bottom row. Also, for the top row we have 17+15+18 = 50 as well.
