Linear Systems Vocab
Section 3.1-3.5
| Question | Answer |
|---|---|
| System of Equations | Two or more equations with the same variables. |
| Consistent Solution | A system of equations that has at least one solution. |
| Inconsistent Solution | A system of equations has no solution. |
| Independent | A consistent system is independent if it has exactly one solution |
| Dependent | A consistent system that has an infinite number of solutions. |
| Substitution Method | An algebraic method where one equation is solved for one variable in terms of the other. Then, this expression is substituted for the variable in the other equation. |
| Elimination Method | Another algebraic method, where you eliminate one of the variables by adding or subtracting the equations. When you add two true equations, the result is a new equation that is also true. |
| System of Inequalities | A set of inequalities with the same variables. |
| Constraints | Conditions given to variables, often expressed as linear inequalities. |
| Feasible Region | The intersection of the graphs in a system of constraints. |
| Bounded | A region is bounded when the graph of system of constraints is a polygonal region. |
| Verticies | The maximum or minimum value that a linear function has for the points in a feasible region. |
| Unbounded | A system of inequalities that forms a region that is open. |
| Linear Programming | The process of finding the maximum or minimum values of a function for a region defined by inequalities. |
| Ordered Triple | The coordinates of a point in space The solution of a system of equations in three variables x,y,and z |
| Octants | The eight regions of three-dimensional space. |
