Answer:
x = 3, y = 8
Step-by-step explanation:
by substitution
4x + (x+5) = 20
5x + 5 = 20
x = 3
y = x + 5 = 3 + 5 = 8
5-(-8)= 5+8=13
13-13=0
3-3=0
No it is 15\ five so the correct answers is number 2 if it was five divided by fifteen it would be 0.3 which is wrong so jus to clarify the answer is the second one.
130 If you multiply that’s what it would give you so I’m not sure what those answers are

Answer:
g(f(x)) = x . . . so the functions are inverses
Step-by-step explanation:
Two functions f and g are inverses of each other if ...
g(f(x)) = x or f(g(x)) = x
We are asked to evaluate g(f(x)). That will be x if the functions are inverses.
g(f(x)) = g((x+1)/2) = 2((x +1)/2) -1 = (x +1) -1
g(f(x)) = x . . . . the functions are inverses
