Inverse Variation
An equation of the form `y = k/x` where `k` is a constant, expresses inverse variation. Just like in direct variation, find the constant of variation, `k`, then use that to see what other variations can be derived from that constant.

Problem Solving Strategy: Use Venn Diagrams
We can use a Venn diagram to illustrate data. A rectangle is used to represent all the data and a circle inside the rectangle is used to represent one group of data. Data that is common to more than one group is represented by the region where interesting circles overlap. Think of the Master Card symbol!

The Real Number System
Rational numbers: Can be expressed as ratios or fractions. With decimal numbers, the part after the decimal either repeats in a pattern or truncates (stops).
Irrational numbers: Cannot be expressed as ratios or fractions. With decimal numbers, the part after the decimal continues WITH NO PATTERN forever. The best example is π.
Both rational and irrational numbers are of the set REAL numbers.
Rational numbers can be (from Chapter 5-1):
- Whole numbers (0, 1, 2, 3 …)
- Integers (-3, -2, -1, -, 0, 1, 2 …)
- Natural numbers (1, 2, 3 …)
And here is a link that gives a few more hints.
There is one more set of numbers outside the REAL numbers. That you learn in Algebra II and that set of numbers is the IMAGINARY set! Wow, imaginary numbers!
