ZONK! Algebra 1 Midterm Review

ZONK! directions 1) Each team will take turns choosing a button that will lead to questions with 200, 400, 600, 800, 1000 points, ZONK!, or a Double ZONK! 2) If a question is drawn, your team must correctly solve the problem to earn points. 3) Drawing a ZONK! means that your team loses the turn and does not earn any points, Double ZONK! means that your team will lose points. 4) When all cards are drawn, the team with the most points wins. HAVE FUN!

400 points The graph shows the height of an object after it is launched into the air. Identify and describe any lines of symmetry. a. x = 3; It takes the object 3 seconds to return to the ground after it is launched. b. x = 1. 5; It takes 1. 5 seconds for the object to reach its maximum height and another 1. 5 seconds to return to the ground. c. y = 36; The object reaches a maximum height of 36 feet. d. There is no vertical line symmetry.
