bigger
Step-by-step explanation:
Answer:
h(x) = 1/4 x - 2
Step-by-step explanation:
f(x) = 4x + 8
y = 4x + 8
x = 4y + 8
4y = x - 8
y = 1/4 x - 2
h(x) = 1/4 x - 2
First, you have to make the denominators the same.
5 1/3 is now 5 4/12
4 3/4 is now 4 9/12
5 4/12
- 4 9/12
4 16/12
- 4 9/12
7/12
Hope this helps!
