Question 4 Select the solution to the following system of equations: \( \begin{array}{l}3 x+2 y=0 \\ -x-y=1\end{array} \) \( \begin{array}{l}x=-3 \\ y=2 \\ x=-2 \\ y=3\end{array} \) \( \begin{array}{l}x=3 \\ y=-2\end{array} \) \( \begin{array}{l}x=2 \\ y=-3\end{array} \)

Example Solve the equation \( 2 x^{2}+4 x-10=0 \) with error precision 0.05

\begin{tabular}{l} Evaluate the expression when \( c=8 \) and \( d=4 \). \\ \( \qquad \frac{48}{c}+d \) \\ \( \square \square \) \\ \hline\( \square \) \\ \hline\end{tabular}

Simplify. \( 6 v+3 v \)

Utiliza logaritmos para resolver: \( 5^{x} = 125 \).

(8) If \( L^{2} \) and \( L \) are the two roots of the equation : \( x^{2}+a x+8=0 \), then \( a=\ldots \ldots \ldots \) \( \begin{array}{llll}\text { (a) }-6 & \text { (b) } 6 & \text { (c) } 4 & \text { (d) } 8\end{array} \)
