question 121

Multiple Choice

Write the system of equations associated with the augmented matrix. Do not solve.
- $$\left[ \begin{array} { r r | r } 9 & - 5 & - 6 \\- 7 & - 2 & - 5\end{array} \right]$$

• A) \(\left\{ \begin{array} { l } - 5 x + 9 y = - 6 \\ - 7 x - 2 y = - 5 \end{array} \right.\)
• B) \(\left\{ \begin{array} { c } 9 x - 5 y = - 6 \\ - 7 x - 2 y = - 5 \end{array} \right.\)
• C) \(\left\{ \begin{array} { l } 9 x - 5 y = 0 \\ - 7 x - 2 y = 0 \end{array} \right.\)
• D) \(\left\{ \begin{array} { c } 9 x - 5 y = - 6 \\ - 2 x - 7 y = - 5 \end{array} \right.\)
