  1. Section 5.3 “Solving Eq. And Ineq. w/ Absolute Value”

  2. The absolute value of a number x, _______, is the ____________________________________. Distance from zero on the # line Ex. ____ & _____

  3. NO SOLUTION An absolute value can never equal a negative number

  4. These examples show that the number inside the absolute value bars can either be positive or negative. We will use this concept to solve equations containing absolute expressions.

  5. Now lets consider inequalities An “or” problem An “and” problem

  6. Have to get the absolute value by itself first

  7. The homework (on a separate sheet of paper) is Hmwk: 1.7 Practice C in the packet 1-6, 13-21
