Asoftball player hits the ball. the height of the ball h (in feet) at any time t seconds after the hit will be represented by the quadratic function h(t)=42t‒6t2. use what you have learned about the zeros of a quadratic function to determine which of the following statements is true. a. the ball will reach the ground in 3.5 seconds. b. the ball will get to its highest point in 7 seconds. c. the ball will stay in the air for a total of 7 seconds. d. the highest the ball will go is about 7 feet.

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.
