To determine if the matrix \( A = \begin{pmatrix} -3 & 3 & 4 \\ -5 & -5 & 8 \\ -1 & -4 & 2 \end{pmatrix} \) is invertible, we need to check its determinant. A matrix is invertible if and only if its determinant is non-zero.

Let me calculate the determinant of this \(3 \times 3\) matrix.

\[
\text{det}(A) = \begin{vmatrix} -3 & 3 & 4 \\ -5 & -5 & 8 \\ -1 & -4 & 2 \end{vmatrix}
\]

I'll compute this step-by-step.The determinant of the matrix \( A \) is approximately \(-1.33 \times 10^{-14}\), which is extremely close to zero. Therefore, the matrix \( A \) is **not invertible**.

Despite the "Yes" being selected in the image, the correct answer is "No" since the determinant is essentially zero.

Here are some related questions:
1. What happens when a matrix has a determinant of zero?
2. How can we compute the inverse of a matrix if it is invertible?
3. What is the geometric interpretation of a matrix's determinant?
4. How do matrix operations affect the determinant?
5. What role does the determinant play in systems of linear equations?

**Tip:** If a matrix's determinant is zero, it means the matrix maps some vectors to the zero vector, implying the transformation is not invertible.

Is the matrix A = ((-3, 3, 4), (-5, -5, 8), (-1, -4, 2)) invertible?

Determine if the matrix A = ((-3, 3, 4), (-5, -5, 8), (-1, -4, 2)) is invertible by calculating its determinant. Understand key concepts in linear algebra, including matrix inversion and determinant properties. Suitable for undergraduate students.
