  12. E E E B E D B E C A Answers Algebra Practice Test 5

  13. ¡ A. ¡ B. ¡ C. ¡ D. -3 ¡ E. 3 1. What is the value of when x = -5?

  14. 1. What is the value of when x = -5? Substitution, watch the signs Spend enough time on simple problems to insure that you have it correct. Answer E

  15. ¡ A. ¡ B. ¡ C. ¡ D. ¡ E. 2. Simplify

  16. 2. Simplify Answer E Now find a common denominator.

  17. 3. In the figure below what is the distance between point A and B? ¡ A. 11 ¡ B. 10 ¡ C. ¡ D. 9 ¡ E.

  18. 3. In the figure below what is the distance between point A and B? Use the Pythagorean Theorem. 4 7 Answer E

  19. 4. In the standard coordinate plane what is the distance between (-5, 2) and (1, -6)? Use the distance formula. ¡ A. 9 ¡ B. 10 ¡ C. ¡ D. 14 ¡ E.

  20. 4. In the standard coordinate plane what is the distance between (-5, 2) and (1, -6)? 6 If you do not like the distance formula you can use the Pythagorean Theorem. 8 10

  21. ¡ A. -18 ¡ B. ¡ C. 9 ¡ D. ¡ E. 5. 27 -2/3 = ?

  22. 6. The parabola below is a graph of which equation? ¡ A. y = (x - 2)2 + 4 ¡ B. y = (x + 2)2 + 4 ¡ C. y = -(x - 2)2 + 4 ¡ D. y = -(x + 2)2 + 4 ¡ E. y = x2 + 4x + 8 (-2, 4) (-4, 0) (0, 0)

  23. 6. The parabola below is a graph of which equation? Because the parabola points down we know that the x2 term will be negative. (Negative Frown Face) ¡ C. y = -(x - 2)2 + 4 ¡ D. y = -(x + 2)2 + 4 Plug (-2, 4) into choice C y = -(x - 2)2 + 4 4 = -(-2 - 2)2 + 4 4 = -(-4)2 + 4 4 = -16 + 4 4 = -12 False Plug (-2, 4) into choice D y = -(x + 2)2 + 4 4 = -(-2 + 2)2 + 4 4 = -(0)2 + 4 4 = -0 + 4 4 = 4 True (-4, 0) (0, 0)
