Holden is trying to determine the velocity of his race car. He went 20 meters east, turned around, and went 40 meters
west. He turned the car one more time and went 35 meters east. His car was 15 meters from the starting line. This took 5
seconds
What is the car's velocity?
3 m/s west
3 m/s east
19 m/s west
19 m/s east

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.
