Algebra practice question
Which of the following describes all values of x that satisfy −3x ≥ 12?
- A. x ≤ −4Correct
- B. x ≥ −4
- C. x ≤ 4
- D. x ≥ 4
Answer: A. x ≤ −4
Dividing by −3 reverses the inequality: x ≤ −4.
Why the other answers are wrong
- B. x ≥ −4
- This forgets to reverse the inequality.
- C. x ≤ 4
- This drops the negative sign.
- D. x ≥ 4
- This drops the sign and does not reverse.
