Unit 2 Systems and equations

1. Explain what the solution to a system of equations is and give examples of one solution, no

solution, and infinite solutions. (include the equations and the graph and an explanation of why it is one, none, or infinite) Classify these as consistent, inconsistent, dependent, or independent.

2. Show an example of how to solve systems of equations by graphing and write the steps in words.

3. Show an example of how to solve by elimination and write the steps in words.

4. Show an example of how to solve by substitution and write the steps in words.

5. Give the key presses to find the solution to a system on the calculator. (Be specific and go step by step)

6. Show how to graph a system of inequalities and explain what the solution set it. Your entry should include the inequalities, graph, and the explanation of the solution.

7. Give an example of maximizing a linear programming problem. Show the problem, how to work it, and all parts of the solution.
