# What is the solution to \frac{x}{-7} \ge 9 written in set notation?

Jun 5, 2018

$x \in \left[- 63 , \infty\right)$

#### Explanation:

$\text{multiply both sides by } - 7$

$\cancel{- 7} \times \frac{x}{\cancel{- 7}} \ge - 7 \times 9$

$x \ge - 63$

$x \in \left[- 63 , \infty\right) \leftarrow \textcolor{b l u e}{\text{in interval notation}}$
