Chapter 3 - Solving Inequalities - 3-3 Solving Inequalities Using Multiplication or Division - Lesson Check: 2

Answer

B

Work Step by Step

We need to get the variable alone. In order to cancel out division, we use multiplication, so we multiply both sides of the equation by -3. However, because we multiply by a negative, we must flip the inequality sign. Thus, we obtain that $ x \gt 3$. This means that the graph should be shaded for all values above 3, making B the correct answer.
