Inequality Systems
Inequality systems are a set of inequalities that are combined together to form a system of equations. These inequalities can be linear or nonlinear, and they can involve one or more variables. Solving inequality systems can be used to find the values of the variables that satisfy all of the inequalities in the system.
There are two main methods for solving inequality systems: the graphical method and the algebraic method. The graphical method involves graphing the inequalities and finding the region that satisfies all of them. The algebraic method involves using algebraic techniques to solve the inequalities.
Solving Inequality Systems Graphically
The graphical method for solving inequality systems is a visual approach that involves graphing the inequalities and finding the region that satisfies all of them. To graph an inequality, first rewrite it in slope-intercept form (y = mx + b).
Then, plot the boundary line of the inequality, which is the line that separates the solutions from the non-solutions. The boundary line will be dashed if the inequality is not an equality, and solid if it is an equality.
Once the boundary line is plotted, shade the region that satisfies the inequality. The region that is shaded will be the solution region. The solution region is the set of all points that satisfy the inequality.
Solving Inequality Systems Algebraically
The algebraic method for solving inequality systems is a symbolic approach that involves using algebraic techniques to solve the inequalities. There are three main algebraic methods for solving inequality systems: substitution, elimination, and using properties of inequalities.
The substitution method involves substituting one inequality into another and solving for the variable. The elimination method involves adding or subtracting the inequalities to eliminate one of the variables. The properties of inequalities method involves using the properties of inequalities to simplify the system and solve for the variables.

FAQ Compilation: Systems Of Inequalities Quiz Part 1
What are inequality systems?
Inequality systems are sets of two or more inequalities that must be solved simultaneously. These inequalities can be linear or nonlinear, and they can involve one or more variables.
How do I solve inequality systems graphically?
To solve inequality systems graphically, you can graph each inequality and shade the region that satisfies the inequality. The solution to the system is the region that satisfies all of the inequalities.
How do I solve inequality systems algebraically?
To solve inequality systems algebraically, you can use a variety of methods, including substitution, elimination, and the multiplication property of inequality. The goal is to isolate the variable on one side of the inequality and solve for its range of values.
