  2. 1. What are the solutions to the quadratic equation

  3. 2. If for all x and y, , then

  4. 3. For all

  5. 4. What is the value of the expression when

  6. 5. If then

  7. 6. For all

  8. 7. Simplify

  9. 8. Simplify

  10. 9. If the ratio of 4 to b is 5 to 7 then b = ?

  11. 10. Which equation best describes this graph?

  12. C A B A B D B B B C Answers Algebra Practice Test 8

  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
