Review of Inequalities Less than/ Greater than Less than or equal to/ Greater than or equal to Represented with an open circle on a number line. Does not include the value Represented with a closed circle on a number line. Includes the value.

Solving Absolute Value Inequalities “LESS THAN” 1. Rewrite with a (-) sign on the left. Use another “less than” sign. 2. Solve for x on all three sides at once! 3. Graph your answer on a number line. X is “in between” the two numbers

Solving Absolute Value Inequalities “GREAT OR THAN” Like oars on a boat! KEEP first equation the same CHANGE to a negative FLIP the inequality OR

Ex : Isolate the absolute value first! Put -3 on the other side, draw a less than sign Solve X is “in between” the two numbers

Ex:2 Isolate the absolute value first! Great OR than: 2 equations! OR Like oars on a boat!

When things get weird… When will an absolute value be BIGGER than a negative number? When will an abs value be SMALLER than a negative number? When will an abs value EQUAL a negative number? Every time! Never!
