Question 8 Find the slope of the line satisfying the given condilions. through \( (6,-6) \) and \( (2,-6) \)

Evalúa \( a+(-b) \), donde \( a=4 \) y \( b=2 \). \( \square \)

Find the relative extreme points of the function, if they exist. Then sketch a graph of the function. \[ \mathrm{G}(\mathrm{x})=\frac{-16}{\mathrm{x}^{2}+2} \]

1. \( 5 x\left(x^{2}-6 x+8\right) \) 2. \( -x^{2}\left(8 x^{3}-11 x+20\right) \) \( 7 x^{3}\left(3 x^{3}-x^{2}+16 x+10\right. \)

11) Discussion Topic: 1. A mass-spring system has a mass ( m ) of 0.5 kg and a stiffness \( (\mathrm{k}) \) of \( 100 \mathrm{~N} / \mathrm{m} \). Calculate the natural frequency ( \( \omega \mathrm{n}) \) of the system.

\( \left. \begin{array} { l } { \frac { 3 } { 4 } - \frac { 2 } { 5 } = \frac { ( 5 ) ( 3 ) } { ( 5 ) ( 4 ) } - \frac { ( 4 ) ( 2 ) } { ( 4 ) ( 5 ) } = \frac { 15 } { 20 } - \frac { 8 } { 20 } = \frac { } { 20 } } \\ { \frac { 1 } { 4 } + \frac { 1 } { 2 } = \frac { 1 } { 4 } + \frac { ( L ) ( 1 ) } { ( ) ( 2 ) } = \frac { 1 } { 4 } + \frac { 2 } { 4 } = - } \end{array} \right. \)
