Quick Quiz #1

Quick Quiz 1. It is worth 5 points. 2. It is timed. 10 minutes 3. You must show your work! 4. You can use your formula sheet from your folder.

Learning Target: I can solve an inequality. 8/20/12Solving Inequalities Page #

Flashback – Solve each equation. 1.2 x – ( x + 7) = ( x + 6) – 15 = 4( x + 3) + x – 5

Flashback – Solve each equation. 1.2 x – ( x + 7) = 28

Flashback – Solve each equation. 2. 3( x + 6) – 15 = 4( x + 3) + x – 5

An inequality contains an inequality symbol. >,, or < You can do the same thing to both sides of an inequality like you did when solving an equation. EXCEPT when you multiply or divide both sides of an inequality by a negative, the inequality symbol is reversed.

3. Solve the inequality and graph the solution on a number line. 2 x – 5 > -29

The last solution of x > -12 can also be written in interval notation. ( , -12)

4.Solve the inequality. Graph the solution on a number line AND write the answer in interval notation. 4( x – 3) + 5 < 2 x + 59

Guided Practice – Solve the inequality, graph the solution set, and write the solution in interval notation. 5. 7(2 x – 4) – ( x + 3) = 8

6. Solve the Inequality. Graph the solution on a number line and write the solution in interval notation. 4 x – (6 x + 18) > -48

Guided Practice – Solve the inequality, graph the solution set, and write the solution in interval notation x – 2(3 x + 7) < 24

Compound Inequalities occur when there are two inequalities solved together. Sometimes it will look like or 2 x < 24.

9. Solve. Graph the solution set and write the solution in interval notation. -7 < 2 x + 1 < 15

10. Solve. Graph the solution set. 4 x + 1> -15 or 2 x < 24

Exit Slip Solve each inequality. Graph the solution set. Write the solution in interval notation.
