### Example Question #1 : Solving Inequalities

Give the solution set of the inequality

**Possible Answers:**

**Correct answer:**

Two numbers of like sign have a positive quotient.

Therefore, has as its solution set the set of points at which and are both positive or both negative.

To find this set of points, we identify the zeroes of both expressions.

Since is nonzero we have to exclude ; is excluded anyway since it would bring about a denominator of zero. We choose one test point on each of the three intervals and determine where the inequality is correct.

Choose :

- True.

Choose :

- False.

Choose :

- True.

The solution set is

### Example Question #2 : Solving Inequalities

Solve for x.

**Possible Answers:**

**Correct answer:**

Solving inequalities is very similar to solving an equation. We must start by isolating x by moving the terms farthest from it to the other side of the inequality. In this case, add 7 to each side.

Now, divide both sides by 2.

### Example Question #3 : Solving Inequalities

Solve for x.

**Possible Answers:**

**Correct answer:**

Solving inequalities is very similar to solving an equation. We must start by isolating x by moving the terms farthest from it to the other side of the inequality. In this case, subtract 2from each side.

Now, divide both sides by 2.

### Example Question #4 : Solving Inequalities

Solve the following inequality:

**Possible Answers:**

**Correct answer:**

To solve for an inequality, you solve like you would for a single variable expression and get by itself.

First, subtract from both sides to get,

.

Then divide both sides by and your final answer will be,

.

### Example Question #5 : Solving Inequalities

Solve the inequality:

**Possible Answers:**

**Correct answer:**

Simplify the left side.

The inequality becomes:

Divide by two on both sides.

The answer is:

### Example Question #6 : Solving Inequalities

Solve the inequality:

**Possible Answers:**

**Correct answer:**

Subtract on both sides.

Add 3 on both sides.

Divide by 7 on both sides.

The answer is:
