Solve these equations. What could x be? -16-x=0

x= -16

Step-by-step explanation:

-16 - (-16)=   -16 + 16 =0

x=-16 because -16-(-16)=0

14

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
