Solve the equation 6(z + 8.5) = 123

z = 12

Step-by-step explanation:

6z + 51 = 123

6z = 123 - 51

6z = 72

z = 12

Hope that helps!

step-by-step explanation:

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
