Linear Inequalities
The solution
to algebraic inequalities consists of a range (or ranges) of numbers. The
solution to linear inequalities will be of the form x < a, x ≤ a, x > a,
or x ≥ a, where a is a number. The inequality x < a means all numbers smaller
than a but not including a; x ≤ a means all numbers smaller than a including a itself.
Similarly the inequality x > a means all numbers larger than a but not a itself,
and x ≥ a means all numbers larger than a including a itself.

Some
geometric problems involve changing one or more dimensions. In the following
problems, one or more dimensions are changed and you are given information about
how this change has affected the figure’s area. Next you will decide how the
two areas are related Then you will be able to reduce your problem from several
unknowns to just one.

Geometric Figures
Algebra
problems involving geometric figures are very common. In algebra, you normally
deal with rectangles, triangles, and circles. On occasion, you will be asked to
solve problems involving other shapes like right circular cylinders and right
circular cones. If you master solving the more common types of geometric
problems, you will find that the more exotic shapes are just as easy.

There are
some distance/rate problems for which there are three unknowns. You must reduce
the number of unknowns to one. The clues on how to do so are given in the
problem.

For distance
problems in which the bodies are moving away from each other or toward each
other at right angles (for example, one heading east, the other north), the
Pythagorean Theorem is used. This topic will be covered in the last chapter.
