Carolyn was asked to solve the following system of equations. Her work is shown. Problem: 3x – 2y = 7 y = x + 2 Carolyn's Work: Step 1 3x – 2(x + 2) = 7 Step 2 3x – 2x + 4 = 7 Step 3 x + 4 = 7 Step 4 x = 3 Step 5 Step 6 y = x + 2 y = 3 + 2 y = 5 (3,5) What error did Carolyn make? Identify her mistake and explain the error.

The graph below shows the price of different numbers of mats at a store: a graph is shown. the values on the x axis are 0, 2, 4, 6, 8, 10. the values on the y axis are 0, 21, 42, 63, 84, and 105. points are shown on ordered pairs 0, 0 and 2, 21 and 4, 42 and 6, 63 and 8, 84. these points are connected by a line. the label on the x axis is number of mats. the title on the y axis is price in dollars. which equation can be used to determine p, the cost of b mats?
