  1. Which is the factored form of x² + 5x + 6?

    Answer: (x + 2)(x + 3)

    2 and 3 multiply to 6 and add to 5, so the answer is (x + 2)(x + 3).

  2. What is the mean of the data set 3, 7, 8, 10, 17?

    Answer: 9

    The sum is 45, and 45 ÷ 5 = 9.

  3. If f(x) = 2x² − 3, what is f(−2)?

    Answer: 5

    (−2)² = 4, so f(−2) = 2(4) − 3 = 5.

  4. Which equation represents a line with slope −3 and y-intercept 4?

    Answer: y = −3x + 4

    Slope-intercept form is y = mx + b, so m = −3 and b = 4 give y = −3x + 4.

  5. Solve the inequality −2x > 8.

    Answer: x < −4

    Dividing both sides by −2 reverses the inequality sign, giving x < −4.

  6. A bag has 3 red, 5 blue, and 2 green marbles. What is the probability of randomly picking a blue marble?

    Answer: 1/2

    There are 5 blue marbles out of 10 total, so the probability is 5/10 = 1/2.

  7. A town's population is 500 and doubles every 3 years. What will the population be after 9 years?

    Answer: 4,000

    9 years is 3 doublings, so 500 × 2³ = 4,000.
