you design a new app for cell phones. your revenue for x downloads is given by f(x)=3x. your profit is $20 less than 90% of the revenue for x downloads create a function p to model the profit. find the profit for 90 downloads

The Break Even point is the point at which the cost=revenue   14,980+20x=30x 14,980=10x 1,498=x   a. 1,498 units must be sold to break even. At $20 per unit, the dollar amount will be $29,960   b. The profit function is P(x)=R(x)-C(x) So P(x)=30x-(14,980+20x) If you want to solve for this equation just enter the value of x we found for the break even point to get the answer.

Hoped I helped

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !

~just a girl in love with shawn mendes

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
