Susie makes jewelry to sell at the flea market. she knows her profit function is p(x)=−2x2+20x−17 and her cost function is c(x)=17+10x, where x is the number of items produced. calculate her revenue function.

Profit = Revenue less Costs. Thus, Revenue = Profit(x) + Costs(x).

Here,

Profit(x) = P(x) = -2x^2 + 20x - 17, and Costs(x) = 17 + 10x. Thus,

Revenue(x) = R(x) = -2x^2 + 20x - 17 + 17 + 10x

R(x) = -2x^2 + 30x (answer)

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
