A)

b)

\bf h'(x)=\stackrel{quotient~rule}{\cfrac{f'(x)(x-6)~~-~~f(x)\cdot 1}{(x-6)^2}}\quad &#10;\begin{cases}&#10;x=5\\&#10;f(5)=5\\&#10;f'(5)=5&#10;\end{cases}&#10;\\\\\\&#10;h'(5)=\cfrac{f'(5)(5-6)~~-~~f(5)\cdot 1}{(5-6)^2}&#10;\\\\\\&#10;h'(5)=\cfrac{5(-1)-5}{(-1)^2}\implies h'(5)=-10\\\\&#10;-------------------------------\\\\

\bf h(5)=\cfrac{f(5)}{5-6}\implies h(5)=\cfrac{5}{-1}\implies h(5)=-5&#10;\\\\\\&#10;\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\quad &#10;\begin{cases}&#10;x=5\\&#10;y=-5\\&#10;\stackrel{m}{-10}&#10;\end{cases}\implies y-(-5)=-10(x-5)&#10;\\\\\\&#10;y+5=-10x+50\implies y=-10x+45

Need help with this one
Anon25 [30]

ANSWER

y =  \frac{10}{3} x - 18

EXPLANATION

The given line has slope

m_{1} =  - 0.3

The line that is perpendicular to this line has a slope that is the negative reciprocal of -0.3

m_2 =  \frac{ - 1}{ - 0.3}

m_2 =  \frac{10}{ 3}

If the line e passes through (3,-8), then the equation is given by,

y -  - 8 =  \frac{10}{3} (x - 3)

y =  \frac{10}{3} x - 10 - 8

y =  \frac{10}{3} x - 18
