- Consistent system
- A system of equations that have at least one solution.
- Constraints
- The inequalities in a ystem of equations whose graphs forms the boundaries of the graph of the system's solution
- Cramer's rule
- A method that uses determinants to solve a system of linear equations.
- Dependent system
- A system of equations that has an infinate number of solutions.
- Determinant
- A square array consisting of numbers or expressions enclosed between two parallel vertical bars.
- Element

1. A number or variable written within a determinant.
2. Each value in a matrix. - Elimination method
- Algebraic method that is used to find the solutions for variables.
- Inconsistant system
- A system of equations that have no solution.
- Independent system
- A system of equations that have exactly one solution.
- Linear programming
- A method for finding the maximum or minimum value of a function in two variables subject to given constraints on the variables.
- Octants
- Three mutually perpendictular planes separate space into eight regions.
- Ordered triple
- The solution of a system of equations in three variables.
- Second-order determinant
- A determinant that has two rows and two columns. Its value can be found by calculating the difference of the products of the two diangonals.
- Substitution method
- Algebraic method of where you substitute for a variable.
- System of equations
- A set of equations with the same variables.
- System of inequalities
- A set of inequalities with the same variables.
- Unbounded
- If a polygonial region is not formed by the constraints of a system of inequalities.
- solve a simpler problem
- Problem solving strategy in which simpler, similar, problem is solved to determine the concepts that can be used in solving a more complex problem.
