#### Answer

4

#### Work Step by Step

To find the missing term in the first equation, transform the second equation so that the left side is -8u.
$u\geq-0.5\longrightarrow$ multiply both sides by -8; reverse the inequality
$u\times-8\leq-0.5\times-8\longrightarrow$ multiply
$-8u\leq4$
The missing term on the right side of the first equation is 4.
