3. Graphing Inequalities

You use a number line to graph an inequality i one variable. Similarly, you use a coordinate plane to graph a linear inequality in two variables (including cases where one of the variables has a coefficient of 0, such as … Continue reading

2. Compound and Absolute Value Equations and Inequalities; And/Or Statements

Compound Inequalities When you have a compound inequality, you must treat it like separate inequalities to ensure you treat everyone equally. For example, the equation: -1<-2x+7<9  has two separate inequalities so when we move numbers across the inequalities we must … Continue reading

1. Applying the Properties of Inequality

You can apply the properties of inequality to solve inequalities. These properties are also true for inequalities involving ≤ and ≥. It is important to note that these properties are very similar to the properties of equality. The only difference is when … Continue reading
