Answer:
$25.57
Step-by-step explanation:
First, you have to multiply $5.29 by 2 because she wants to spend $5.29 on 2 pairs of socks.
5.29 * 2 = $10.58
Then you want to add $10.58 and $14.99 together.
$10.58 + $14.99 = $25.57
Each ratio is

Y=mx+b
b represents your y-intercept
mx represents your slope
(a) since we are given that f(8) = 9, the inverse of 9 is simply 8. Therefore, f^-1(9) = 8.
(b) Again, f is the inverse of f^-1, therefore, you simply switch numbers, and you get that f(-3) = -7.
