I am stuck on these problems:
A = [ 5 7 ] A^-1 = [ a b ]
[ 7 10] , then [ c d ] , c =
would c = -7?
and......
A = [ 5 7 ]
[ 0 10 ] [ [3 2 ]
and then AXB will have which of the following:
b = [ 1 0 3 ]
[ 2 1 0 ]
3 rows and 3 columns
2 rows and 3 columns
3 rows and 2 columns
2 rows and 2 columns
none listed
Now I think it is 2 rows and 2 colums, but I am not forsure.
