1. Bell Ringer: 8/17/15  Solve the following equation:

2. 1-3 and 1-4 Solving Multi- Step Equations Learning Target : I can solve linear equation, with absolute value and apply to the real world.

3. Recall: Multi-Step Equations: Steps to solving:  Use Distributive property to get rid of parentheses  Combine like terms on each side of equals sign  “Move” variables to left of equals sign by adding or subtracting  “Move” constants to right of equals sign by adding or subtracting  Get variable by itself by either dividing or taking the root.

4. Examples:

5. Solving Equations with Absolute Value  What is the definition of absolute value?  In order to solve equations with absolute value, you must isolate the expression with absolute value first. Then you apply the definition of absolute value to solve the equation.  Challenge ?: At most, how many solutions are in an absolute value equation?

6. Examples:

10. Sec 1-5: Inequalities Learning Target : I can solve simple inequalities and apply them to real world situations.

11. Inequalities: These are solved in the same way as equations, however, if you multiply or divide by a negative value, the inequality symbol reverses.

12. Inequalities:  Words:  Greater than  Less than  Greater than or equal to  Less than or equal to  Symbols:  >  <  ≥  ≤

13. Inequalities:  Words:  Greater than  Less than  Greater than or equal to  Less than or equal to  On the number line:  >, open circle, shade right  <, open circle, shade left  ≥, closed circle, shade right  ≤, closed circle, shade left

18. Sec 1-6: Compound Inequalities Learning Target : I can solve compound inequalities, including those with absolute value and apply them to real world situations.

19. Compound Inequalities:  Defined as two inequalities joined by the word “and” or the word “or.” In order to solve a compound inequality you must solve each part of the inequality.  Generally, “and” compound inequalities have the algebraic expression in between two values with < or ≤ ; “or” statements use one of each inequality symbol.
