The answer is 2x-5 (I hope that's what you meant)
Answer:
The answer is C.
Step-by-step explanation:
In order to find x, you have to multiply both sides by 40 :



The sum can be rewritten as y=4x, where y=f(x).
Now, we can rewrite the equation a x=y/4
Therefore, inv(f(x))=x/4
Answer: V=7.605π
Step-by-step explanation:
The cylinder formula is V=πr^2h
Substitute the values.
V=π(1.3)^2(4.5)
V=π(1.69)(4.5)
V=7.605π
Hope this helps!
