Anthony has a lunch account in the school cafeteria. The balance, g(x), in his account at the beginning of the month can be represented by the function g(x) = -2.50x +32, where x is the number of meals purchased. 1. How much money was in Anthony's account at the beginning of the month? 2. What is the slope of the graph of this function? 3. What does the slope represent in the context of the problem? 4. Find g(x) when x =11. What does this pair of values mean in the context of the problem?

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
