integral of-0.4x+20

Solution

\int - 0.4 x + 20 d x

Solution

- 0.2 x^{2} + 20 x + C

Solution steps

\int - 0.4 x + 20 d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= - \int 0.4 x d x + \int 20 d x

\int 0.4 x d x = 0.2 x^{2}

\int 20 d x = 20 x

= - 0.2 x^{2} + 20 x

Add a constant to the solution

= - 0.2 x^{2} + 20 x + C
