  13. 1. What are the solutions to the quadratic equation Factor. You need two numbers that will multiply to 36 and add to -15. + 37 20 15 13 12 Now use the zero factor property. Answer C

  14. 2. If for all x and y, , then Solve for b. Add b to both sides. Answer A

  15. 3. For all Factor. Cancel. Answer B

  16. 4. What is the value of the expression when Substitute and simplify. Answer A

  17. 5. If then Radical Equation First isolate the radical. Subtract 4 from both sides. Square both sides to get rid of the radical. Subtract 5 from both sides. Divide by 5. Answer B

  18. 6. For all Find the square root of x9. Each pair of (xx) inside represents one x outside. Choice D is the only answer that matches this result.

  19. When raising a power to a power multiply the exponents. 7. Simplify Answer B

  20. Simplify the radicals. 8. Simplify The common denominator is 3 Answer B

  21. 9. If the ratio of 4 to b is 5 to 7 then b = ? Write the proportion as two equal fractions. Cross multiply. Divide by 5. Answer B

  22. 10. Which equation best describes this graph? The y-intercept of the graph is (0, 3). This eliminates choices A and E. The point (0, 3) works in B, C, and D.

  23. 10. Which equation best describes this graph? Try the point (-1, 4) in B. This eliminates choice B. Try the point (-1, 4) in D. This eliminates choice D.

  24. 10. Which equation best describes this graph? Try the point (-1, 4) in C. Answer C
