What is 3/20 in the lowest simplest form

Sketch one cycle if the cosine function y=2cos2theta

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.

Y=21.95x+10 y=22.45x solve by substitution
