Freddy spent $56.07 on 4 pairs of jeans at the store. his cost included $4.15 sales tax. how much was each pair of pants?

a negative exponent is translated as follows:

so, we have

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
