253 * 0.27= 68.31 (discounted price)
253-68.31 OR 253*0.73= 184.69 (sale price)
If any team is duplicated in the result (occurs more than once), do not include that result in the final data.
Answer:
a) r(x) = 28x
b) p(x) = -x^2 +30x +9
c) 15
Step-by-step explanation:
a) Let x represent the number of items sold. Each sale results in $28 of revenue, so the revenue function r(x) is ...
r(x) = 28x
__
b) p(x) = r(x) - c(x) = 28x -(x^2 -2x -9)
p(x) = -x^2 +30x +9
__
c) The axis of symmetry of ax^2 +bx +c is -b/(2a). Here, the axis of symmetry of the profit function is ...
x = -30/(2(-1)) = 15
15 is the quantity of sales that maximizes profit.

Answer:
The midpoint is (1,-13.5)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates of the endpoints and divide by 2
(7+-5) /2 = 2/2 =1
To find the y coordinate of the midpoint, add the y coordinates of the endpoints and divide by 2
(-12+-15) /2 = -27/2 =-13.5
The midpoint is (1,-13.5)
