Laurie is designing a type of candy dispenser for use at grocery stores. When pressure is applied to a lever by the customer, candy will fall into a container. As pressure on the lever increases, so will the amount of candy that is dispensed. For each pound per square inch of pressure placed on the lever, the amount of candy dispensed will triple. Which of the following does this situation represent? A. a relation only
B. a function only
C. neither a relation nor a function
D. both a relation and a function

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.
