Ever just do other people’s hw instead of your own? i’m so done.

Sorry guys but as you have a small brain

How can you tell when x and y are not directly proportional?

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
