  1. 3. is an equation with no solution.
  2. 5. are either a single number or variable, or numbers and variables multiplied together and they are separated by + or − signs.
  3. 8. 2 terms, For example, 2x+1
  4. 12. is a portion on a number line or what is between two points or values.
  5. 14. is a statement that two ratios are equal. Example (a/b)=(c/d).
  6. 15. 3 terms, For example, 2x+y+1
  7. 17. can have constants, variables, and exponents, but never division by a variable.
  8. 18. is an angle that measures 180.
  9. 19. 1 term, For example, 2
  10. 20. is an equation in which variables are used to describe a relationship.
  11. 21. angles are an angle that measures 90.
  12. 23. is an equation that is true for some values of the variable and false for others.
  13. 24. that have exactly the same solution sets. For example, 2x=10 → x=5
  14. 25. is statements relating algebraic expressions using < or > or ≤ or ≥, ≠

  1. 1. a special notation that uses parentheses ( ) and/or brackets [ ] to describe an interval on a number line.
  2. 2. are two integers that differ by 1.
  3. 4. angles are two angles whose measure has a sum of 90.
  4. 6. is the set of all solutions of an equation. { }
  5. 7. are two angles whose measure has a sum of 180.
  6. 9. is an equation that is true for all values of the variable.
  7. 10. Polynomial It is customary to write the terms of a polynomial in the order of descending powers of the variable.
  8. 11. is any number divided by 0 because dividing by zero is undefined.
  9. 13. is a comparison of two quantities using a quotient (a/b) or (a:b) or (a to b)
  10. 16. Solution Set = empty set = ∅ empty set, "{ }," or ∅ or "phi"
  11. 22. are angles formed by intersecting lines and they have the same measures.
