Should you save it, invest it, or enjoy it? Learn how inequalities can help you make your decision!
So an inequality is just an equation with a less than or greater than symbol. But what is the difference between 1 and 2 variable inequalities? What does have a greater than or equal to symbol change? When do you use a number line instead of a coordinate plane? Get those answers here! In this lesson, we'll explore the conditions of compound inequalities and learn how to express them using set notation and interval notation.
Test you knowledge afterward with a short quiz. If you're already pretty familiar with what inequalities are and just looking for a place to practice your skills, this is the place.
This lesson covers topics like 1-variable, 2-variable, compound, and systems of inequalities. Taking two skills and combining them to make a more complicated problem is a classic tactic in mathematics.

The Inequalities chapter of this Precalculus Homework Help course helps students complete their inequalities homework and earn better grades. This homework help . Overview While equations are statements that two quantities are equal, inequalities state that quantities are not equal. One side of the expression might be greater than the other side, or one side of the expression may be less.
Systems of linear inequalities can be solved graphically, by using substitution, or by using elimination. The graphics show the intersection of solutions.
