Dakota's Scribe Post for Friday(3/28/08)

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

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.

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
