Algebra practice question
On a number line, a graph shows an open circle at 3 with shading to the right. Which inequality is graphed?
- A. x > 3Correct
- B. x ≥ 3
- C. x < 3
- D. x ≤ 3
Answer: A. x > 3
An open circle excludes 3; shading right means larger values.
Why the other answers are wrong
- B. x ≥ 3
- A closed circle would be needed to include 3.
- C. x < 3
- Shading would be to the left.
- D. x ≤ 3
- Wrong direction and wrong circle.
