3/8x+1/3y=17/24 X+7y=8

guajiro [1.7K]

Multiplying the first equation and multiplying it by -8/3 (to get rid of the x), we get -8y/9+7y= -64+8=-56. Therefore, -56/(-8/9+7)=y and 8- 7(-56/(-8/9+7))=x by plugging it into the second equation

Answer:

Average rate of change is - 1/6 or -0.166…

Step-by-step explanation:

${ \tt{f(x) = \frac{1}{x - 5} }}$

f(-1):

${ \tt{f( - 1) = \frac{1}{( - 1 - 5)} }} \\ = { \tt{ - \frac{1}{6} }}$

f(3):

${ \tt{f(3) = \frac{1}{3 - 5} }} \\ = { \tt{ - \frac{1}{2} }}$

Average rate of change:

$= { \bf{ \frac{f(3) - f(-1)}{2} }}$

${ \tt{ = \frac{ - \frac{1}{2} - ( - \frac{1}{6} ) }{ 2 } }} \\ \\ = { \tt{ - \frac{1}{6} }}$
