16. Joe has 5 sports cards. He bought 3 packs with
the same number of cards in each pack. If he
now has 35 cards in all, how many were in each
pack? Write an equation, and show how to solve
it algebraically. Verify your answer by substituting
it in your equation or by using algebra tiles.

In the past, professional baseball was played at the astrodome in houston, texas. the astrodome has a maximum height of 63.4 m. the height of a baseball t seconds after it is hit straight up in the air with a velocity of 45 ft/s is given by h = -9.8t2 + 45t + 1. will a baseball hit straight up with this velocity hit the roof of the astrodome? use the discriminant to explain your answer.

Find the zero function by factoring (try to show work) h(x)=-x^2-6x-9
