Question

(\frac{4}{5} geq -10u)

Explanation:

Step1: Divide both sides by -10 (reverse inequality)

When dividing an inequality by a negative number, the inequality sign flips. So we divide both sides of $\frac{4}{5} \geq -10u$ by -10:
$\frac{\frac{4}{5}}{-10} \leq u$

Step2: Simplify the left - hand side

Simplify $\frac{\frac{4}{5}}{-10}=\frac{4}{5}\times(-\frac{1}{10}) = -\frac{4}{50}=-\frac{2}{25}$

Answer:

$u\geq-\frac{2}{25}$
