  2. Solve the equation for x: • x = 7 • x = 5 • x = 7 & x = -5 • x = 7 & x = 5 [Default] [MC Any] [MC All]

  3. Find the value(s) of r that would make the equation true. • r = 7 & r = -7 • r = 7 • r = 49 • r = 98 [Default] [MC Any] [MC All]

  4. Find a value of n so that the following equation has solutions at x = 8 & x = -8 • 64 • 0

  5. One solution to the equation below is j = 4. What is the other number which would make the equation true? • -10 • 0

  6. Given: n > 0Conclusion: the following equation will have 1 solution. • True • False

  7. The formula for the height of an object above the ground, dropped at a height of 100 meters, can be given by the function shown below. H is the height above the ground and t is in time. How long will it take for an object to fall to the ground if dropped from a height of 100 meters? (put zero in for H) • 2.5 • 0

  8. Which of the following are solutions of the equation (t + 6)(2t – 9) = 0 ? • t = 5 & t = 0.2 • t = -6 • t = 4.5 • t = -6 & t = 4.5 [Default] [MC Any] [MC All]

  9. Solve the equation for x: • x = 5.5 • x = 1.5 & x = -7 • x = 5.5 & x = 7 • x = -7 [Default] [MC Any] [MC All]

  10. Determine the values of the variable, t, that makes the equation true. One value is 6, what is the other value? • 2 • 0
