Solving One-Step Inequalities and Graphing Solutions

The video tutorial explains how solving inequalities differs from solving equations, emphasizing the need to flip the inequality sign when multiplying or dividing by a negative number. It covers the steps to solve one-step inequalities using inverse operations and demonstrates graphing solution sets. The tutorial includes eight example problems, illustrating the process of solving and graphing inequalities.

What is the main difference between solving inequalities and solving equations?

• You need to add a constant to both sides.

• You need to flip the inequality sign when multiplying or dividing by a negative number.

• You need to multiply both sides by a positive number.

• You need to subtract a constant from both sides.

When solving the inequality x/3 ≥ -5, why is the inequality sign not flipped?

• Because the inequality sign is already correct.

• Because the number being divided is negative.

• Because the number being multiplied is positive.

• Because the variable is on the left side.
