Answer:

$\boxed{\begin{bmatrix} 3 & - 1 \\ - 3 & 4\end{bmatrix} = 12 - 3 = \boxed{9} }\\ \\ \boxed{\begin{bmatrix} -12 & - 1 \\ 12 & 5\end{bmatrix} = - 60- ( - 12) = \boxed{ - 48}} \\ \\ \boxed{\begin{bmatrix} 0& - 1 \\ 17 & 4\end{bmatrix} = 0 -( - 17 )= \boxed{17}} \\ \\\boxed{ \begin{bmatrix} 8& - 1 \\ - 4 & - 1\end{bmatrix} = - 8 - 4 = \boxed{ - 12} }\\ \\ \boxed{\begin{bmatrix} 2 & - 1 \\ 2 & - 1\end{bmatrix} = - 2 - ( - 2) = \boxed{0}} \\ \\ \boxed{ \begin{bmatrix} 1 & 0\\ 0 &1\end{bmatrix} = 1 - 0 = \boxed{1}}$

Step-by-step explanation:

$the \: determinant \: of \: a \: matrix : A \to\\If \: A =\begin{bmatrix} x & y \\ a & b \end{bmatrix} \: then : \\ its \: determinant \: is \: givn \: by \to \\ |A| = (b \times x) - (a \times y) \\ \boxed{|A| = bx - ax}$
