5. Let $A \in M_{n \times n}(\mathbb{F})$ be an invertible matrix, and let $u \in \mathbb{F}^n$ be a column vector. For each $1 \le i \le n$ let $A_i(u)$ be the matrix obtained from $A$ by replacing the $i$th column of $A$ with $u$. Also, let $x_i = \text{det } A_i(u) / \text{det } A$, and let $x \in \mathbb{F}^n$ be the column vector $x = \begin{bmatrix} x_1 \ \vdots \ x_n \end{bmatrix}$. Show that $Ax = u$.

2. For circuits in Figs. 2 and 3: (a) Write an expression for the output voltage, $V_o$, in terms of the resistor symbols and the input voltage symbols. (b) Evaluate the specific output voltage, $V_o$, for the given value of resistors and input voltages. (c) Determine the input resistance seen by voltage source $V_1$. (d) Determine the input resistance seen by voltage source $V_2$. $R1 = R2 = R3 = R4 = R5 = 10 k\Omega$ $V_1 = V_3 = +5 Vdc$ $V_2 = +15 Vdc$
