Question
Answer
Two or more equations with the same variables.   Systems of Equations  
🗑
A system with at least one solution.   Consistant  
🗑
A system that has no solutions. (i.e. Parallel lines.)   Inconsistant  
🗑
A system with exactly one solution.   Independent  
🗑
A system with an infinite number of solutions. (i.e. When each equation in the system makes the same line.)   Dependent  
🗑
The method of solving a system in which one equation is solved for one variable in terms of the other.   Substitution Method  
🗑
The method of solving a system by eliminating one variable in the system by adding or subtracting the equation.   Elimination Method  
🗑
Two or more inequalities with the same variables.   System of Inequalities  
🗑
Conditions given to variables, often expressed as linear inequalities.   Constraints  
🗑
The intersection of the graphs in a system of constraints.   Feasible Region  
🗑
A regions is bounded when the graph of a system of constraints is a polygonal region.   Bounded  
🗑
The maximum or minimum value that a linear function has for the points in a feasible region.   Vertices  
🗑
A system of inequalities that forms a region that is open.   Unbounded  
🗑
The process of finding the maximum or minimum values of a function for a region defined by inequalities.   Linear Programming  
🗑
1. The coordinates of a point in space. 2. The solution of a system of equations in three variables (x, y, and z.)   Ordered Triple  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
