7ms. walker's science class is doing an egg drop experiment from the balcony of their school. each egg is protected by a contraption that the students collectively designed. the height of the egg, in feet, after x seconds is given by the expression below. what do the zeros of the expression represent? a. the horizontal distance traveled by the egg b. the maximum height of the egg c. the time at which the egg reaches the ground d. the time at which the egg reaches its maximum height reset next

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.
