Warm-Up - methods of graphing lines in the form ax + by = c
Try viewing MathTV for a refresher on how to graph lines of this form... On the left side of the screen press Algebra, then Linear Equations in Two Variables (straight lines) then choose the following problems:
For an example of the slope-intercept method - choose problem #4 - Betsy as the tutor
For an example of the intercepts method - choose #7 - Preston (English) or David (Spanish)
Launch/Explore
Problems #1-2 on page 68 - be sure to READ all the information before and between problems
Summary
Explain #1a and #2e to Ms. Totman
Homework - finish HW#12 from Friday, if necessary. Otherwise, no homework
Wednesday, 2/22
I apologize for the lateness of this post. I've been experiencing a combination of computer struggles and after-school meetings and have been unable to keep up as well as I'd like.
Continuing on with our exploration of "linear programming", we began writing inequalities (for our constraints) and equations (for our objective function) and using the graph to find the feasible points and those most worth our effort (along the border of the feasible region).
Explore: p. 70 #3
Homework #13: p. 71 #4
Thursday, 2/23
Continue to work in groups on linear programming problems.
Today - Paizan's Pizza Problem (you can download by clicking on the link)
HW#14: p. 80 #1a-e (that's abcde)
Friday, 2/24
Wrap up Paizan's Pizza Problem -
1.) the maximum or minimum objective function will occur at the corners of the feasible region. Be sure to use these when searching for your best solution!
2.) Don't trust your graph when looking for the corners... use a graphing calculator OR algebraic reasoning to find the intersection points!
Proficiency Check - Just Graphing
Make sure all homework #12-14 is complete and turned in by Monday.
