Use an inverse matrix to solve the system of equations, if possible. 2x + 3y = 2
x – 4y = -21

What is the distance between (–2 1/2,-3) and (1, –3)?

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
