What is the value of x in the equation 3x-4y=65 when y=4?
Simple...plug n chug..
3x-4(4)=65
3x-16=65
Now, isolate the variable, x....
3x-16=65
+16 +16
3x=81
Now, divide,
x=27.
Thus, your answer.

Answer:
Yes, Rolle's theorem can be applied
There is only one value of c such that f'(c) = 0, and this is c = 1.5 (or 3/2 in fraction form)
Step-by-step explanation:
Yes, Rolle's theorem can be applied on this function because the function is continuous in the closed interval (it is a polynomial function) and differentiable in the open interval, and f(a) = f(b) given that:
Then there must be a c in the open interval for which f'(c) =0
In order to find "c", we derive the function and evaluate it at "c", making the derivative equal zero, to solve for c:
There is a unique answer for c, and that is c = 1.5
