Answer:
B 5x = 25
Step-by-step explanation:
Please mark brainliest ;)
Given y = xy + x^2 +1, first find y = f(x) = (x^2 + 1) / (1 - x). Then use the quotient rule for derivatives.
dy/dx = [( 1 - x)( 2x) - (x^2 + 1)(-1)] / (1 - x)^2. Substitute the value of x = -1 into the above derivative and get -1/2.
EDIT
Answer: x≤6
Explanation: the total number of hours (x) is less than or equal to 6 hours.
Because if you check my math below where I misread the question and gave a function... LOL
You will see that 7 hours would be too many.
So very sorry for the initial confusion!!
Answer: f(x)=12X-15
Step-by-step explanation:
X represents the number of hours.
F(1)= 12(1)-15 = $-3 or free. In real life I'm sure there'd be a requirement that you rent at least 2 hours to get the discount
