  1. 1. 3.  Determining Equivalence.notebook February 06, 2013 Determining Equivalence 1
  2. 2. 3.  Determining Equivalence.notebook February 06, 2013 Goal: Determine if two or more expressions are equivalent. 2
  3. 3. 3.  Determining Equivalence.notebook February 06, 2013 Happy Wednesday! Todays warm­up is Mental Math #1­5. When you are finished, please take out your homework and a red pen. Solve each equation or inequality for the variable: 1) 2x + 2 > 4 2) 2(x + 2) ­ 3x > ­ 2 3) 5(x ­ 3) + 4 = 4) ­ 3(c+4) ­ 2 > 7 5) ­ 9 = 8 + [ 3 ­ (2x + 4)] ­ 6x 3

  14. 14. 3.  Determining Equivalence.notebook February 06, 2013 Key Question: Is plugging in one value to both expressions good enough to determine equivalency? Lets try 2x + 1 and x + 2. Evaluate for x = 1. Are the expressions equivalent? 14
  15. 15. 3.  Determining Equivalence.notebook February 06, 2013 Key Question: Is plugging in one value to both expressions good enough to determine equivalency? Lets try 2x + 1 and x + 2 again. This time evaluate for x = 3. Are the expressions equivalent? 15
  16. 16. 3.  Determining Equivalence.notebook February 06, 2013 Key Question: Is plugging in one value to both expressions good enough to determine equivalency? This time well use y = 4(x + 2) ­ 4 and y = 4(x + 1). Evaluate for x = 1 and x = 2 Are the expressions equivalent? Do you need at least two values to produce the same answer to confirm that expressions are equivalent? 16
  17. 17. 3.  Determining Equivalence.notebook February 06, 2013 Why are two values for x y = 4(x + 2) ­ 4 good enough to determine equivalent expressions? y = 4(x + 1) 17
