  1. 3. Two simple inequalities joined by the word OR.
  2. 5. A compound inequality joined by the word AND; solutions that satisfy both parts of the compound inequality are solutions to the conjunction.
  3. 10. The set of points on a number line, or on a plane, that represents the solution of an inequality.
  4. 12. A set that contains all the values for a variable that make the equation or inequality true.
  5. 13. The value of the variable that makes the equation or inequality a true sentence.
  6. 14. The set of all possible input values of a relation or function, or x-values, in ordered pairs.
  7. 15. An inequality that involves more than one operation.

  1. 1. The theorem stating that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.
  2. 2. The point on a number line where the graph of a linear inequality in one variable starts.
  3. 4. Two simple inequalities joined by the word AND or OR.
  4. 6. Shows the endpoints of a solution set. All the real numbers between these endpoints are in the interval.
  5. 7. A statement whose solution process ends in a false numerical statement; its solution set is the null set.
  6. 8. An equation with two or more variables.
  7. 9. An inequality that contains an absolute-value expression.
  8. 11. An algebraic, or variable, equation showing relationships among quantities.
