Multiplication and Division Inequalities

Question 4 • SC-Mathematics 6

Solve the inequality 171 > -6x, and graph the solution. What does the graph look like?

Answer
A
an open circle at –28.5 and an arrow pointing right
B
an open circle at –28.5 and an arrow pointing left
C
an open circle at 28.5 and an arrow pointing right
D
an open circle at 28.5 and an arrow pointing left

Explanation

Divide both sides of 171 > -6x by -6. Because you divide by a negative number, reverse the inequality sign: -28.5 < x, or x > -28.5. The graph has an open circle at -28.5 and an arrow pointing right, so the correct choice is an open circle at –28.5 and an arrow pointing right.
