**Matrix Linear Combination Exercise** In this exercise, you are asked to express matrix \( B \) as a linear combination of matrices \( A_1 \) and \( A_2 \), if possible. If it is not possible, you should enter "DNE" (Does Not Exist) in all blanks. Given matrices: \[ B = \begin{bmatrix} 2 & 7 \\ 4 & 5 \end{bmatrix}, \quad A_1 = \begin{bmatrix} 1 & 2 \\ -1 & 1 \end{bmatrix}, \quad A_2 = \begin{bmatrix} 0 & 1 \\ 2 & 1 \end{bmatrix} \] Task: Write \( B \) as a combination of \( A_1 \) and \( A_2 \): \[ \begin{bmatrix} 2 & 7 \\ 4 & 5 \end{bmatrix} = (\text{blank}) \begin{bmatrix} 1 & 2 \\ -1 & 1 \end{bmatrix} + (\text{blank}) \begin{bmatrix} 0 & 1 \\ 2 & 1 \end{bmatrix} \] If you need additional help, please click the "Read It" button.
