What is the unit rate of 2.5 miles in 11.5 minutes

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

Simplify. (-2)^-3 a. -8 b. -1/8 c. 1/8 d. 8

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2
