Use the Left and Right Riemann Sums with $100$ rectangles to estimate the $($signed$)$ area under the curve of $y=-9x+10$ on the interval $0,50.$ Write your answer using the sigma notation.

Left Riemann Sum $={\displaystyle \underset{i=0}{\overset{99}{}}}(,)$

Tries $3/99$ Previous Tries

Right Riemann Sum

Tries $\frac{0}{99}$
