Derivative using direct definition of derivative 2-x/2+x

Daniel [21]

Let f(x) = (2 - x)/(2 + x). By definition of the derivative,

$\displaystyle f'(x)=\lim_{h\to0}\frac{f(x+h)-f(x)}h$

$\displaystyle f'(x)=\lim_{h\to0}\frac{\frac{2-(x+h)}{2+(x+h)}-\frac{2-x}{2+x}}h$

$\displaystyle f'(x)=\lim_{h\to0}\frac{\frac{(2-x-h)(2+x)-(2-x)(2+x+h)}{(2+x+h)(2+x)}}h$

$\displaystyle f'(x)=\lim_{h\to0}\frac{-4h}{h(2+x+h)(2+x)}$

$\displaystyle f'(x)=-4\lim_{h\to0}\frac1{(2+x+h)(2+x)}=\boxed{-\frac4{(2+x)^2}}$

-10n+50=-7(4n+8)-2 no solution many solution

ziro4ka [17]

Answer:

n=-6

Step-by-step explanation:

distribute -7 into (4n+8)

-10n+50=-28n-56-2

combine like terms

-10n+50=-28n-58

add -28n on both sides

-10n+28n+50=-58

combine like terms again

18n+50=-58

subtract 50 on both sides

18n=-108

divide both sides by 18

$\frac{18x}{18} =\frac{-108}{18}$

x=-6
