If f(x) = ln(1 − 5x), then find f '(x).

The formula for the derivative of the ln function, with chain rule, is

(d/dx) ln u = (1/u)(du/dx).

Here, u = 1 - 5x, and du/dx = -5.

Then df/dx = [ 1  /  1-5x ]*(-5), or

df        -5

=

dx      1-5x

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
