8th Grade Topic 1 Question

• Why can absolute value equations have more than
  one solution or no solution?

4
8th Grade Topic 1 Answer

• The expression inside the absolute value symbols
  can be either positive or negative. This would
  give you more than one answer.
• If the problem has no solution it is because it
  has a negative answer. Absolute value is NEVER
  equal to a negative value, so the problem does
  not have a solution.

8th Grade Topic 5 Answer

• An expression doesnt have a given value.
  Example 3x - 8
• An equation has a given value shown with an equal
  sign.
• Example 3x - 8 -5
• An inequality has a range of answers. Example
  3x - 8 lt 5, x lt4, so any number less than 4 would
  be a correct answer to the inequality.
