![The image displays three matrix multiplication problems, represented as follows:
1. **First Equation:**
\[
\begin{bmatrix}
-2 & -6 & 5 \\
-4 & -1 & 1 \\
1 & -8 & 7
\end{bmatrix}
\begin{bmatrix}
4 \\
7 \\
-5
\end{bmatrix}
=
\begin{bmatrix}
\\
\\
\\
\end{bmatrix}
\]
2. **Second Equation:**
\[
\begin{bmatrix}
-2 & -6 & 5 \\
-4 & -1 & 1 \\
1 & -8 & 7
\end{bmatrix}
\begin{bmatrix}
-8 \\
-1 \\
-3
\end{bmatrix}
=
\begin{bmatrix}

3. **Third Equation:**
\[
\begin{bmatrix}
-2 & -6 & 5 \\
-4 & -1 & 1 \\
1 & -8 & 7

Each problem shows a matrix multiplication that needs to be completed. The first two equations involve multiplying a 3x3 matrix by a 3x1 vector, and the third equation involves multiplying a 3x3 matrix by a 3x2 matrix, resulting in a 3x2 matrix. The resulting matrices are left blank, indicating spaces where the solution to the matrix multiplication should be placed.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcf673b33-84d3-4207-a3d8-77b439e8ab65%2Ff25d4c31-93e2-496e-9f9b-77acf3ea7c74%2Fj1cmgjf_processed.png&w=3840&q=75)
