  1. Chapter 7 – Algebra CP BAAM!

  2. RULES1. Decide which team goes first.2. Appoint a scorekeeper. 3. Teams answer correctly and earn money. If a team is correct, they can continue until max. 3 times or until they get BAAM!4. If a team hits BAAM! they go bankrupt!5. The team with the most money at the end is the winner. BAAM!

  4. What is the axis of symmetry and vertex? y=-2x2-3x+10 x=-3/4 (-3/4, 89/8) $100

  5. BAAM! Say ‘goodbye’ to your money!

  6. Irrational or rational? irrational $10

  7. BAAM! You are broke!

  8. Solve the equation. 6 (x2 - 2) = 12 2, -2 $600

  9. Solve the equation. 9 (w2 + 1) = 9 W = 9 $300

  10. BAAM! Where’s your money gone?

  11. BAAM! Unlucky!

  12. What is the axis of symmetry? y = x2 + 6x - 2 x = - 3 $100

  13. BAAM! Oh dear!

  14. True or false? If it is false, write a true statement. X2 – 10 = 3, there is 1 solution. False, there are 2 solutions. $10

  15. Graph using a table. y = -x2 + 1 Opens down, vertex at (0,1)

  16. Graph using a table y = x2 - 4 Opens up, vertex at (0, -4) $600

  17. BAAM! Oops!

  18. The area of a circle is given by the formula A=πr2. Find the radius of a circle with area 16 in2 to the nearest inch. 2.3 in

  19. Use the quadratic formula to solve 2x2 – 7x = -3 3, 0.5

  20. Rational or irrational? rational $10

  21. Write a quadratic equation that has no solution. Discriminant must be negative.

  22. Solve the equation x2 = -5x - 6 x = -2, -3

  23. Graph y < x2

  24. Find the axis of symmetry and vertex. y = 2x2 – 6x x = 3/2 (3/2, -5/2)

  25. Simplify +13 $100

  26. Which two integers is between? -8 and -7 $700

  27. BAAM! You lost everything!

  28. Solve x2 – 63 = 81 x = 12, -12

  29. Great Job!
