  1. Section 2-4 Absolute Values in open Sentences DO NOW: Take out your homework from last night, your notes, a calculator, and pencil. Objective: To solve open sentences involving absolute value

  2. Review from section 2-2 Problem Solution The problem asks for the maximum number of shares of each stock Let a= number of shares of stock A, Then a+100= number of shares of stock B. 18.5a+24.75(a+100)>22 a+(a+100 Solve • The Perez family has 100 more shares of stock B than of stock A. The current price per share of stock A is $18.50 and stock B is $24.75. At most how many shares of each do they have if the average price per share is greater than $22?

  3. Review Problem Solve • The Perez family has 100 more shares of stock B than of stock A. The current price per share of stock A is $18.50 and stock B is $24.75. At most how many shares of each do they have if the average price per share is greater than $22?

  4. 2-4 Absolute Value in Open Sentences • Sentence • |x|= Distance between x and 0 equals 1 • |x| >1 Distance between x and 0 is greater than 1 |x|<1 Distance between x and 0 is less than 1 • Graph Equivalent Sentence X=-1 or x=1 X<-1 or x>1 -1 <x<1

  5. SOLVE: |3x-2|=8 3x-2= -8 3x-2=8 3x-2=8 • 3x-2= -8 OR Find the Solution Set

  6. |3-2t|<5 • Solve: |3-2t|<5 • Solution: |3-2t|<5 is equivalent to this conjunction • -5<3-2t<5

  7. Solve |2z-1|+3> • And graph it’s solution set

  8. Use this time to start in on your homework • Page 75, section A 9,10,17 • Section B 19, 20 • Section C 33 Did we reach out objective: To solve open sentences involving absolute value
