3/29 Adv. Alg/Trig Bell Ringer Graph and write the solution set for |x – 3| < 6
3/29 News and Notes • Perfection: 4th • ACT Prep Tomorrow! • Missing Quizzes: • 2nd: Jazmyn • 4th: Raven, Victor, Arielle, Kyle 2 DAYS LEFT!!!!!
This week’s plan • Mon: Absolute Value Inequalities (AND) • Today: Absolute Value Inequalities (OR) • Wed: Review Day • Thurs: Quiz • Fri: Day off!
Example #1 2 min: Discuss what this inequality is asking for in words: The set of numbers that are greater than 4 units from zero.
Example #1 What are a couple examples of numbers that are greater than 4 units from zero? Ex: 5, 6, 7, 8…, -5, -6, -7, -8…
Example #1 You must SWITCH the sign when putting in negative form OR -4 4
Let’s Summarize then do 1 more • Key #1: Positive and Negative Forms • Key #2: The sign on the negative form must be switched! • Key #3: When greater than, we need OR • Key #4: Graph and solution set are the values OUTSIDE!
Example #2 You must SWITCH the sign when putting in negative form OR
Check your answer • Plug a number back in to make sure it works!
Independent Practice • You must check your answers on every single question!
Exit Ticket • Which of the following is the correct solution set for |x – 5| > 7 • A. X > -2 OR x < 12 • B. 2 > x OR x < 12 • C. -2 < x < 12 • D. 12 < x OR x < 17
