Answer: 1 < x < 5.
- A 1 < x < 5
- B x > 5
- C x < 1
- D no solution
Correct answer: A. 1 < x < 5
Explanation: The values satisfying both conditions lie between 1 and 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.
