derivative of

f (x) = 5 x + 7

\frac{5}{2 5 x + 7}

Solution steps

\frac{d}{d x} (5 x + 7)

Apply the chain rule:

\frac{1}{2 5 x + 7} \frac{d}{d x} (5 x + 7)

= \frac{1}{2 5 x + 7} \frac{d}{d x} (5 x + 7)

\frac{d}{d x} (5 x + 7) = 5

= \frac{1}{2 5 x + 7} \cdot 5

Simplify

\frac{1}{2 5 x + 7} \cdot 5 : \frac{5}{2 5 x + 7}

= \frac{5}{2 5 x + 7}
