  1. Literal Equations Coordinate Algebra Standard: A.CED.4

  2. Essential Question: • How do I rearrange formulas to highlight a quantity of interest?

  3. Vocabulary • A literal equation is an equation that contains two or more variables.

  4. Info: • Formulas are examples of literal equations: • Volume of a cube: V = s3 • Area of a circle: A = Πr2 • Area of a rectangular solid: A = lw

  5. Solving… • You will be given a formula and asked to solve for a specific variable. • You will need to use inverse operations to isolate that variable.

  6. Example 1 • A = lw; for l • lw is joined by what operation? • Multiplication • What’s the inverse? • Division • Divide both sides by?? • w… • A/w = l

  7. Example 2 • A = ½bh; for b • Clear the fraction first by taking the reciprocal and multiplying. • 2A = bh • Divide by h • 2A/h = b

  8. Example 3 • V = lwh; for h • Divide by BOTH lw at the same time. • V/lw = h

  9. Example 4 • y = 3x – 2; for x • Add 2 • Divide by 3 • 1/3y + 2/3 = x

  10. Homework: • Worksheet • Due tomorrow
