Answer: It reverses: -x < -5.
- A It stays the same: -x > -5
- B It reverses: -x < -5
- C It becomes an equation
- D It becomes undefined
Correct answer: B. It reverses: -x < -5
Explanation: Multiplying or dividing both sides of an inequality by a negative number reverses the inequality sign.
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.
