  1. Solve: x + 5 > 9

    Answer: x > 4

    Subtract 5 from both sides to get x > 4.

  2. When must you flip the inequality symbol while solving?

    Answer: When multiplying or dividing by a negative number

    Multiplying or dividing both sides by a negative number reverses the inequality direction.

  3. Solve: 3x ≤ 12

    Answer: x ≤ 4

    Divide both sides by 3 to get x ≤ 4.

  4. How is x > 3 shown on a number line?

    Answer: Open circle at 3, shading right

    x > 3 uses an open circle (3 not included) with shading to the right.

  5. Solve: -2x > 8

    Answer: x < -4

    Divide both sides by -2 and flip the inequality: x < -4.

  6. Which inequality represents 'at least 5'?

    Answer: x ≥ 5

    'At least 5' means 5 or more, which is x ≥ 5.
