Question
**Finding the Inverse of a Matrix**

**Problem Statement:**
Find the inverse of the matrix.
\[ \begin{bmatrix} 5 & 5 \\ -6 & -5 \end{bmatrix} \]

**Instructions:**
Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice.

**Options:**
- **Option A:**
\[ \left( \begin{bmatrix} 5 & 5 \\ -6 & -5 \end{bmatrix} \right)^{-1} = \begin{bmatrix}
\quad \boxed{} & \quad \boxed{} \\[6pt]
\quad \boxed{} & \quad \boxed{}
\end{bmatrix} \]
(Simplify your answers.)

- **Option B:**
The matrix is not invertible.

**Explanation:**
To declare the matrix invertible, calculate its determinant. If the determinant is non-zero, the matrix is invertible, and we can proceed to find its inverse. If the determinant is zero, the matrix is not invertible.

**Graph/Diagram Analysis:**
The given matrix is \[ \begin{bmatrix} 5 & 5 \\ -6 & -5 \end{bmatrix} \]. Options provided include selecting whether the matrix is invertible and if so, computing the values of its inverse entries. To solve for the inverse when the determinant is non-zero, use the formula for the inverse of a 2x2 matrix:
\[ \text{If } A = \begin{bmatrix} a & b \\ c & d \end{bmatrix}, \text{ then } A^{-1} = \frac{1}{ad - bc} \begin{bmatrix} d & -b \\ -c & a \end{bmatrix}.\] The determinants, intermediate steps, and verification should be calculated to finalize the correct answer.

**Further Discussion:**
Consider working through the determinant calculation and necessary algebraic steps to verify the correct choice between options A or B. Ensure to simplify answers in option A for correct entries if the matrix is indeed invertible.
