Question | Answer |
System of Linear Equations
p.329 | a set of two or more linear equations containing two or more variables |
Solution of a System of Linear Equations
p.329 | an ordered pair that satisfies each equation in the system - the place where the graphs of the equations intersect |
Solving a system by Substitution
p.336 | a method other than graphing that reduces a system to one equation that has only one variable so that you can solve for that variable's value |
Solving a system by Elimination
p.343 | a method other than graphing that reduces a system to one equation that has only one variable by eliminating one of the variables through adding or subtracting the two equations |
Consistent Systems
p.350 | systems that have at least one solution |
Inconsistent Systems
p. 350 | systems that are parallel and therefore have no solution |
Independent Systems
p.351 | a consistent system that has exactly one solution - it's graph appears as two intersecting lines |
Dependent Systems
p.351 | a consistent system that has infinitely many solutions - it's graph places each line on top of the other (coincident), and appears as only one line |
Linear Inequality
p.364 | similar to a linear equation, but the equal sign is replaced with an inequality symbol |
Solution of a Linear Inequality
p.364 | any ordered pair that makes the inequality true |
System of Linear Inequalities
p.371 | a set of two or more linear inequalities containing two or more variables |
Solutions of a System of Linear Inequalities
p.371 | all or the ordered pairs that all of the linear inequalities in the system |
