For each of the following, use the rules of matrix algebra to show that the relationship is true. Don’t replace the matrices by matrices with actual numbers nor generic matrices in which you use dot products to perform the multiplication. You should be able to show these using the representation of a matrix by a single letter, which is one of the strengths of the matrix representation of the relationships between values.

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b
