Today in class we learned about multiplying matrixes. When multiplying you must mutiply first and then add to get the correct answer. For example for problem #! you would multiply 4*20(cars) and 6*25(trucks) and then add them together to get the total number of (w)wheels= 230


Notes:
1. Matrix Multiplication

BE [20 25] * c⎡4 2 1⎤ = BE [230 65 95]

Today, we reviewed LS-46 from yesterday. Then, we moved on to a new unit and were introduced to matrices. We completed LS-54 and 55, where we learned what matrices are and how they can be used. Other than that, we didn't do anything else today.

Algebra 2 notes for LS 36

1.

Point G

Y= 14-2x - Seats

Y= 6- 4/6x - Wheels

Point D

Y=6-4/6x - wheels

Y= 5-1/3x- gas tank

2.

profit= 1x+2y

3.

x+2y=Profit

x+2y=11

2y=11-x

y= 11/2- x/2

4.

3x+2y=profit

2y=p-3x

y=p/2-3/2x

Classwork for 7-Mar-08

Today in class we went over again how to complete the square and how to put equations into graphing form. The classwork reviewed increasing and decreasing values in LS-1. In the problems LS2-5 the classwork explained and demonstrated absolute value and how it is different than the positive or negative value of a number.

March 11, 2008 today in class essentially we went over a few problems from homework that Mr. Rochester thought were tough problems we also went over problems that my classmates suggested were a little challenging. Here are the class notes below.
