Comparing Matrices

[saxplaya]

Hi guys!!

im currently taking algebra II and i kind of need help on this problem...


Compare the quantity in Column A with the quantity in Column B.

A .......... B
[7 ..... 7]... [1/4 ..6]
[-1.. 1/2]... [-50 ..12]

are they equal?
same?
or
cannot be determined from this info?

tks,
tim

Looks to me - you have two 2x2 matrices (A & B) instead of two column vector.

      |7     7  |
A =   |         |
      |-1   0.5 |

and

      |0.25  6  |
B =   |         |
      |-50   12 |

for two matrices to be equal, each corresponding term must be equal, i.e.

iff

\(\displaystyle [A] \, = \, \)

then

\(\displaystyle a_{ij} \, =\, b_{ij}\)
