Answer: x ≤ 2.
- A x ≤ 2
- B x ≥ 2
- C x < 0
- D x > 2
Correct answer: A. x ≤ 2
Explanation: Adding 2 to both sides gives x ≤ 2.
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.
