Given cost function is
c(x) =
(20 ≤ x ≤ 400)
where x is the number of thousands of square feet
total revenue will be $0.2 million dollars per thousand square feet
Revenue is 0.2 millions per thousand square feet. we know x is the number of thousand of square feet
So R(x) = 0.2x
We know Profit = Revenue - Cost
P(x) = R(x) - C(x)


combine like terms

Profit function is

Answer:
12m-18-3m=2m+m-18
9m-18= 3m-18
9m-3m=18-18
6m=0
m=0/6=0
Step-by-step explanation:
You can figure the line for each pair of points, or you can try the points in the equation you have and see which are on the line.
First answer: x=1, y=-5×1 +4 = -1 . . . not 9. (1, 9) is not a point on the line
Second answer: x=2, y=-5×2 +4 = -6 . . . not -14. (2, 14) is not a point on the line
Third answer: (see the calculation for the first answer) . . . -1 ≠ 1. (1, 1) is not a point on the line
Fourth answer: (see the calculation for the second answer) We know that (2, -6) is on the given line. Checking (4, -16), we find it is as well.
The appropriate choice is the 4th answer:
... a line passing through the points (2, -6) and (4, -16)
Answer:
Step-by-step explanation:
3a^4 -2a^2 + 5 - 10 -(2a^4 +4a^2 + 5a -2)
as given.. i'm wondering if the 5 in the first group is really 5a.. hmmm
I'm guessing that it is... soooo distribute the minus sign
= 3a^4 - 2a^2 +5a -10 -2a^4 -4a^2 -5a +2
= a^4 -6a^2 -8 :) voila that's your answer
