integral from-7 to 9 of (x/2+9)

Solution

\int_{- 7}^{9} (\frac{x}{2} + 9) d x

Solution

152

Solution steps

\int_{- 7}^{9} \frac{x}{2} + 9 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_{- 7}^{9} \frac{x}{2} d x + \int_{- 7}^{9} 9 d x

\int_{- 7}^{9} \frac{x}{2} d x = 8

\int_{- 7}^{9} 9 d x = 144

= 8 + 144

Simplify

= 152
