What do u add to 5/7/8 to make 8

The coordinates of a, b, and c in the diagram are a(p,4), b(6,1), and c(9,q). which equation correctly relates p and q? hint: since is perpendicular to , the slope of × the slope of = -1. a. p - q = 7 b. q - p = 7 c. -q - p = 7 d. p + q = 7

How many solutions does the nonlinear system of equations graphed below have?

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?
