Cuál par ordenado es una solución de la ecuación? \( y=7 x-2 \) Escoge 1 respuesta: A) Solo \( (3,15) \) B Solo \( (-1,-10) \) C Tanto \( (3,15) \) como \( (-1,-10) \) D Ninguna

ermine the vilue (s) of \( x \) andy if \( y=\frac{10-x}{2 l} \)

\( \left. \begin{array} { l } { \lim _ { x \rightarrow 3 } \frac { x ^ { 2 } - 9 } { x ^ { 2 } - 5 x + 6 } } \\ { \lim _ { x \rightarrow 3 } \frac { \sqrt { x + 1 } - 2 } { x - 3 } } \\ { 2,2 / 8 } \\ { 3 _ { 2 } / 2 / 3 } \end{array} \right. \)

Use graphical methods to solve this linear programming problem. Minimize \( \quad \begin{aligned} z=4 x+7 y \\ \text { subject to: } \\ \begin{array}{rl}x-y & y \\ 3 x+2 y & \geq 18 \\ x \geq 0, y & \end{array}\end{aligned} \)

a) \( 12 / 18 \) al simpliticar por obtiene b) \( 15 / 20 \) al simplificar por obtiene c) \( 6 / 14 \) al simplificar por
