The coordinates of A, B, and in the diagram are A{p.4). 86,1), and 49,q). Which equation correctly relates p and g?
Hint: Since AB is perpendicular to BC, the slope of AB x the slope of BC = -1
A p+q=7
B. P-9=7
OC. 9-p=7

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.
