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.

Select the correct answer. which exponential function has an x-intercept? oa. (x) - 100x-5-1 ob. (x) = 3x4+2 oc. kx) = 7x-1 + 1 od. 1(x) =-3x+1 - 3
