Answer:
f(h(x)) = x
h(f(x)) = x
Step-by-step explanation:
f(x) = 8x-7
h(x) = x+7/8
We need to find f(h(x)) and h(f(x))
Finding f(h(x))
Putting value of h(x) into f(x) i.e
f(h(x)) = 8(x+7/8)-7
f(h(x)) = x+7-7
f(h(x)) = x
Now finding h(f(x))
h(f(x)) = (8x-7)+7/8
h(f(x)) = 8x-7+7/8
h(f(x)) = 8x/8
h(f(x)) = x
Answer: x = 15
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3*x-5-(40)=0
