We are given f(x) = 5x
and we are to find inverse of f(x).
Step 1:
Replace f(x) by y.
So,
y = 5x
Step 2:
Isolate x
So,
x = y/5
Step 3:
Replace x by f'(y)
So,
f'(y) = y/5
Step 4:
Replace all occurrences of y by x.
So,
f'(x) = x/5
Therefore, the inverse of f(x) = 5x is f'(x) = x/5
Answer:
x=12
Step-by-step explanation:
2x-4=x+8
2x-x=4+8
1x=12
12/1=12
12=x
-5.4 - (2.1 + 1.8)=-9.3
So I would say A. Thanks for asking your question today and have a good day on Brainly.com! :)
