integral from 0 to 9 of 9-x

Solution

\int_{0}^{9} 9 - x d x

Solution

\frac{81}{2}

+1

Decimal

40.5

Solution steps

\int_{0}^{9} 9 - x 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}^{9} 9 d x - \int_{0}^{9} x d x

\int_{0}^{9} 9 d x = 81

\int_{0}^{9} x d x = \frac{81}{2}

= 81 - \frac{81}{2}

Simplify

81 - \frac{81}{2} : \frac{81}{2}

= \frac{81}{2}
