Across
- 3. -labeled I,II,III< and IV as shown
- 5. property -which can be used to find the product of a number and a sum or difference.
- 8. term -has a number part but no variable part such as 8 in the expression above.
- 11. inverse -the opposite of a is its additive inverse
- 12. numbers -is the set of all rational and irrational numbers as illustrated in the venn diagram below.
- 13. number -ia a number a/b where a and b are integers and =0
- 15. inverse -zero does not have a multiplicative inverse because there is no number such that o a = 1
- 18. square -as shown in example 1 the square root of a perfect square is an integers.
- 19. absolute value -for example 4 and -4 are opposite because they are both 4 units from 0 but are on opposite sides of 0.
- 20. -the number or expression inside a radical symbol is the radicand.
- 21. of change -compare a change in one quantity to change in another quantity
Down
- 1. identity -the identity property states that the product of a number a and 1 is a
- 2. square -an irrational number of two integers
- 4. statement -has a hypothesis and a conclusion.
- 6. -two lines in the same plane are parallel if they do not intersect
- 7. identity -the inverse property states that the sum of a number a and its opposite is 0
- 9. -of a nonvertical line is the ratio of the vertical change
- 10. coefficient -the number part of a term with a variable part is called coefficient of the term
- 14. terms -are terms that have the same variable part such as -x and 2x in the expression above.
- 16. -are numbers -3,-2,-1,1,2,3.
- 17. expressions -the equation 3(x+2)=3(X)+3(2).
