Question

(a) $A^{-1} = \begin{bmatrix} 2 \\ 3 \end{bmatrix}$ (b) $(7A)^{-1} = \begin{bmatrix} -3 \\ -2 \end{bmatrix}$ (c) $(5A)^{-1} = \begin{bmatrix} -3 \\ 5 \end{bmatrix}$ (d) $(I_2 + 2A)^{-1} = \begin{bmatrix} -1 \\ 4 \end{bmatrix}$

          (a) $A^{-1} = \begin{bmatrix} 2 \\ 3 \end{bmatrix}$ (b) $(7A)^{-1} = \begin{bmatrix} -3 \\ -2 \end{bmatrix}$ (c) $(5A)^{-1} = \begin{bmatrix} -3 \\ 5 \end{bmatrix}$ (d) $(I_2 + 2A)^{-1} = \begin{bmatrix} -1 \\ 4 \end{bmatrix}$

(a) A^-1 =
< b m a t r i x > (b) (7A)^-1 =
< b m a t r i x > (c) (5A)^-1 =
< b m a t r i x > (d) (I2 + 2A)^-1 =
< b m a t r i x >
