  1. Which of the following is NOT a linear equation?

    Answer: y = x² + 4

    y = x² + 4 is a quadratic equation because it contains x raised to the second power.

  2. Simplify: 3x + 2y - x + 5y

    Answer: 2x + 7y

    Combine like terms: (3x - x) + (2y + 5y) = 2x + 7y.

  3. If f(x) = 3x - 2, what is f(4)?

    Answer: 10

    Substitute x = 4: f(4) = 3(4) - 2 = 12 - 2 = 10.

  4. What is the y-intercept of the line y = 5x - 8?

    Answer: -8

    In slope-intercept form y = mx + b, the y-intercept b equals -8.

  5. Solve: 2(x - 3) = 10

    Answer: 8

    Divide both sides by 2: x - 3 = 5, then add 3: x = 8.

  6. Which inequality represents 'a number n is at least 15'?

    Answer: n ≥ 15

    'At least 15' means n is 15 or more, which is written as n ≥ 15.

  7. A taxi charges a flat fee of $3 plus $2 per mile. Which equation represents the total cost C for m miles?

    Answer: C = 2m + 3

    The flat fee is $3 (starting value) and $2 per mile gives C = 2m + 3.
