Algebra II

1. equation where variables represent known values. formulas are a common example (v = lwh)
7. number considered in comparative relation to a whole. equation in which two ratios are set equal to each other (7/3 = x/27)
10. undoes operation of f. opposite in position. (2 + 3 = 5 5 - 3 = 2)
12. give share of something. gives the same answer as two numbers being added together. [(5+2) x 3 = 5x3 + 2x3]
13. finding which prime number to multiply together to make the original number. (24 = 2^3 x 3)
16. equation that follows rules. must be positive. (ax + by = c)
17. number made by dividing two intergers. a number that can be written as a fraction (0.125)

2. a whole number. not a fraction or decimal. (3)
3. to connect with something. the way three or more terms are grouped doesn't change the sum.[(a+b) + c = a + (b+c)]
4. value of a real number. no regard to sign |-8|=8
5. describes direction. describes steepness of a line. (rise/run)
6. proportion of something. not a whole number. (3/4)
7. equation of a straight line. a linear function based on two given coordinates. (y-y1)
8. a number that can't be written as a fraction. a repeating decimal. (π)
9. one part in every hundred. hundredth part of a quantity. (50%)
11. how many times one number contains another. how many times one number enters another. 8:4
14. a whole number that's not a fraction. a whole number that's not a decimal. (4)
15. equation that gives straight line on graph. must have either one or two real variables. (c = 2 x π x r)
