Answer:
B. f -1(x) = x + 2 / 5
Step-by-step explanation:
To find the inverse of a function we need to interchange x and y an solve for y.
Since 
, then
Add 2 to both sides
Divide both sides by 5
We can conclude that the correct answer is B. f -1(x) = x + 2 / 5
Answer:
31
Step-by-step explanation:
although we cannot see the whole graph, I assume it would be 31 because
2010-1979 is 31
and the x values are years after 1979
I believe you would solve for X like: 3x-10=2x-10.

The area of a square is calculated suing the formula x^2, where x is a side length of the square. This is just like length times width because a square has equal side lengths.
Take the left side and add the two lengths together because they form one side length of the square. A side length of the square is x + 4.
To find the area using the side length x + 4, you would square the side length. Your answer is (x + 4)^2.
