use the fact that matrices A and B are row-equivalent.
![The image presents two matrices labeled \( A \) and \( B \), outlined as follows:
### Matrix \( A \) (4x5 matrix):
\[
A = \begin{bmatrix}
-2 & -5 & 8 & 0 & -17 \\
1 & 3 & -5 & 1 & 5 \\
3 & 11 & -19 & 7 & 1 \\
1 & 7 & -13 & 5 & -3 \\
\end{bmatrix}
\]
### Matrix \( B \) (4x5 matrix):
\[
B = \begin{bmatrix}
1 & 0 & 1 & 0 & 1 \\
0 & 1 & -2 & 0 & 3 \\
0 & 0 & 0 & 1 & -5 \\
0 & 0 & 0 & 0 & 0 \\
\end{bmatrix}
\]
These matrices are each 4 rows by 5 columns in dimensions.
- In matrix \( A \), each element is an integer, with a mix of positive and negative values, indicating diverse dataset values.
- Matrix \( B \) has a more structured form with many zeros, appearing to highlight specific columns or rows for certain operations, possibly useful in identity transformations or filtering specific vector spaces.
These matrices might be utilized in various mathematical contexts like linear algebra operations, matrix multiplication, or systems of equations.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa19a6abe-3b19-4c4d-aaff-322af5c5797a%2F1c8f7730-81a5-40a5-bbe5-db941b67f034%2Fzkwnkaf_processed.png&w=3840&q=75)
