1. Tuesday, May 11th Bell Ringer: Use the calculator to solve this system of equations by graphing

2. Bell Ringer Answer Let’s use the graphing calculator

3. Systems Test Tomorrow 10 questions –Solving by graphing using the calculator –Solve by substituion –Solve by linear combinations –Solve by any method you want –Solve word problems

4. Review Session Today After school in my room Candy will be provided!!!!!!!!

5. Example #1 A landscaping company placed two orders with a nursery. The first order was for 13 bushes and 4 trees, and totaled $487. The second order was for 6 bushes and 2 trees, and totaled $232. The bills do not list the per-item price. What were the costs of one bush and of one tree?

6. What are the variables? A landscaping company placed two orders with a nursery. The first order was for 13 bushes and 4 trees, and totaled $487. The second order was for 6 bushes and 2 trees, and totaled $232. The bills do not list the per-item price. What were the costs of one bush and of one tree? b= Price of one busht= Price of one tree

7. Lets write the first equation A landscaping company placed two orders with a nursery. The first order was for 13 bushes and 4 trees, and totaled $487. The second order was for 6 bushes and 2 trees, and totaled $232. The bills do not list the per-item price. What were the costs of one bush and of one tree?

11. Let’s Look at our system Now, How can we solve this? Graphing Substitution Linear Combinations

12. Graphing It is best to use graphing when one variable is solved for in both equations…. So should we use graphing….? NO

13. Substitution It is best to use Substitution when one equation already has a variable solved for…. So should we use substitution….? NO

14. Substitution It is best to use Linear combinations when we can make a magic pair…. So should we use linear combinations….? YES!!!!!!

15. Now lets solve Do you can we make a magic pair?

16. Example #2 Equation #1 Equation #2

17. Example #2

21. So our solution is So bushes cost $23 and trees cost $47

22. Rest of Class Complete as much of the review sheet as possible Test Tomorrow Review session today after school – my room 234, candy will be provided
