  1. Solve the inequality: 2x - 5 > 9

    Answer: x > 7

    Add 5 to both sides to get 2x > 14, then divide by 2 to get x > 7.

  2. What is the y-intercept of the line y = -3x + 6?

    Answer: 6

    In y = mx + b form, b is the y-intercept, which is 6 here.

  3. Simplify: (2x^3)(3x^2)

    Answer: 6x^5

    Multiply coefficients (2 x 3 = 6) and add exponents (3 + 2 = 5) to get 6x^5.

  4. Which expression represents the area of a rectangle with length (x + 4) and width (x - 2)?

    Answer: x^2 + 2x - 8

    Multiply (x + 4)(x - 2) using FOIL: x^2 - 2x + 4x - 8 = x^2 + 2x - 8.

  5. What is the solution to the equation x^2 - 5x + 6 = 0?

    Answer: x = 2 or x = 3

    Factoring gives (x - 2)(x - 3) = 0, so x = 2 or x = 3.

  6. A cell phone plan costs $20 plus $0.10 per text message. Which equation models the total cost, C, for t text messages?

    Answer: C = 20 + 0.10t

    The fixed cost of $20 plus a variable cost of $0.10 per text gives C = 20 + 0.10t.
