6) Identify the point(s) of intersection of each pair of functions. a. = 3x + 15 y = 3 3x y − b. = 3x 8 y x2 − − = 2 y 7) Solve each quadratic equation. a. 6 = 0 b. 5x2 8 = 12x x2 x − − – c. 8x 20 = 0 d. 2y2 5y = 12 x2 − – − 8) Micah was given $200 for his birthday. Each week he spends $15 on comic books. In how many weeks will his birthday money be gone? Create multiple representations (table, graph, and equation) for the relationship between the weeks birthday and how much money he has left. How since Micah’s does each representation show the solution to the problem?
