  1. Turn in Section 8 & 9 Take out spiral notebook

  2. Turn Quiz into INBOX Pick up 6-5 Study Guide Complete #1-9 on scratch paper. Do not write on worksheet until you receive further instructions.

  3. Absolute Value Day 1 Review

  4. Steps for Solving Abs. Value Equations • Isolate the absolute value. • Break into two equations. • Solve each equation. • Write solution set with two values. • Graph on number line.

  5. Invalid Equations The absolute value of a number or expression can never be negative. Example: abs(x – 1) = -2

  6. Absolute Value Day 2 Review

  7. Solving and Graphing Absolute Value Inequalities pg 160 • Isolate the absolute value. • Break into two inequalities. • Sign is the same on first inequality. • Reverse sign on the opposite case. • Graph on the number line. • > OR – shade out • < AND – shaded in between

  8. Solving and Graphing Absolute Value Inequalities • GreatOR than is an OR statement • Shade out • Less thAND is an AND statement • Shade in between

  9. Empty Set • Abs (x – 1) < -4 • Absolute value cannot be less than a negative number. • Empty set – no solution

  10. All real numbers • Abs (x + 5) > - 8 • Absolute value is ALWAYS greater than a negative number. • All real numbers.

  11. Additional Notes • +- notation: see white board • Set notation x < 5 AND x > 1 is {x: 1 < x < 5} m > -1 OR m < -7 is {m: m > -1 or m < -7}
