determine whether the product is defined or undefined is defined give the dimensions of the product matrices 1 1 -4 5 6 0 9 1 -7

Answer 1

To determine if the product of matrices is defined, we need to check if the number of columns in the first matrix is equal to the number of rows in the second matrix.

Given the first matrix:
1 1
-4 5
6 0
9 1
-7

To determine the dimensions of the first matrix, we count the number of rows and columns:
- There are 5 rows in the first matrix.
- There are 2 columns in the first matrix.

Given the second matrix:
?

We don't have the second matrix's values to determine its dimension. Thus, we cannot determine if the product of the matrices is defined.
