Answer 7

The Chain Rule
dy/dx = dy/du *du/dx

let u= (1-2x)

then use the rule above....

Answer 8

i got 1/(1-2x)^2 thank you(:

Answer 9

thats right, right?

Answer 10

Not sure where you got your exponent from...

Answer 11

doesn't look right to me - haven't done th esum - but ther is prolly a 2* something in there from du/dx

Answer 12

^Indeed there will be a "times" 2 because you need to take the derivative of the inside function as well

Answer 13

\[\frac{d}{du} \ln u = \frac{1}{u}\]
\[\frac{d}{dx} (1-2x) = -2\]

Answer 14

ohh so it would be 1-2x sorry!

Answer 15

1/1-2*

Answer 16

1/1-2x* lol my bad

Answer 17

slow down - do the process methodically

Answer 18

@dumbcow has given you nearly all you need

Answer 19

\[\frac{dy}{dx} = \frac{1}{u}* (-2) = \frac{-2}{1-2x}\]
