Answer:
-0.5x² + 20x + 100
Step-by-step explanation:
Given:
R = 25x - 0.5x²
C = 100 + 5x
P = R - C
Where,
P = profits
R = Revenue
C = Cost
which expression represents her profit in dollars?
P = R - C
R = 25x - 0.5x²
C = 100 + 5x
= 25x - 0.5x² -(-100 + 5x )
= 25x - 0.5x² + 100 - 5x
= -0.5x² + 20x + 100
The expression which represents her profit in dollars is -0.5x² + 20x + 100
Answer:
75% off
Step-by-step explanation:
I would personally say use a calculator, but whatever your instructor says.
First, do $600 off. You could also do 75% off first, but you choose. If you subtract $600 from $868, you get $268.
Next, do 75% off. If you take 100% - 75%, you get 25%, or 1/4. Multiply $868 by 1/4 and you get $217, which is the better deal.
So, to conclude, $217 is less than $268, and therefore 75% off is the better deal.
It is 9 because you need to triple 3 so 3x3 is 9
Answer:
When -8 is x then y = -29
When -4 is x then y = -17
When 4 is x then y = 7
When 6 is x then y = 13
Step-by-step explanation:
You simply substitute the numbers on the x row for x in the equation, then you solve the problem. (3 x -8) - 5, ect.
