Step-by-step explanation:

2. 8n= -2

n= -1/4

4. -8s= 32

s= -4

6. 1/7b= -7

b= -49

215.92 dollars is the answer

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
