Systems Quiz - Solving Systems by any method

Solve systems of equations: graphing, tables, matrices & word problems!

1. Solve the following system by graphing.y = 2x + 4y = -3x - 6 2. For each table write an equation in slope-intercept form. Then solve the system. Hint… use STAT Editto get your y = equations. Remember to give me the solution to the system in addition to the equations. 3. Mrs. Ballero has two equations graphed on her calculator. She wants to find the solution, but hates messing with her window. She looked at her table to find the solution. What did she put on her answer key?Using the table above, what is the solution? 4. Solve the following system using a Matrix. 5. Solve the following systems of equations by Graphing. 6. Solve the following using any method. 7. Solve the following system using any method. 8. Tickets to the football game cost $1.50 for students and $4.00 for adults. A total of 250 people attended the game. The total revenue from the box office was $500. Use s for the number of students and a for the number of adults that attended the game.Which answer shows the correct system of equations for this situation?A. 1.50s + 4a = 250 s + a = 500B. s + a = 250 4s + 1.50a = 500C. s + a = 250 1.50s + 4a = 500D. 4s + 1.50a = 250 s + a = 500 A B C D 9. Solve the system of equations below by using a Matrix.x + y = 9002.5x + 5y = 3000 10. A store sells bags of pecans for $3.00, bags of walnuts for $3.50, and bags of almonds for $4.00. One day, 15 bags of nuts were sold, and $53 was earned for the sales. Two more bags of walnuts were sold than pecans. Use the following system of equations below to solve the word problem. Solve using Matrices. Make sure that you pay close attention to the last equation in the system... is it ready for a Matrix yet?
