Answer: 2 ≤ x < 5.
- A 2 ≤ x < 5
- B only x < 5
- C only x ≥ 2
- D 2 < x ≤ 5
Correct answer: A. 2 ≤ x < 5
Explanation: Dividing every part by 2 gives 2 ≤ x < 5.
One-variable inequalities use open (excluded) or closed (included) circles on a number line; two-variable inequalities use a dashed (strict) or solid (non-strict) boundary line, with the solution being the entire shaded half-plane on one side of it.
Concept context
Solving linear inequalities in one and two variables algebraically and graphically, and representing solutions on a number line or as a region in a plane.
