The total profit P of manufacturing x hundred DVD's is given by the equation below. P = 600 + 1,500x − 100x2
Find x if the total profit is $5,600.

x = -7.5

Step-by-step explanation:

P = 600 + 1,500x − 100x^2

P = − 100x^2 + 1,500x + 600

x = -b/2a

1500/ (2 x -100)

x = -7.5

the first one, all those points on the line just make a strait line.

it would open into a square depending on the type of envelope i’m not sure about the second part
