Question

-2u-9 is greater than or equal to -19

Answer 1

First, let’s rewrite the equation:

`\sf{-2u - 9 \geq -19}`

Next, we add 9 to both sides to isolate the coefficient:

`\sf{-2u - 9 + 9 \geq -19 + 9}`

`\sf{-2u \geq -10}`

Finally, we divide both sides by the coefficient (-2) and switch signs:

`\sf{u \leq 5}`

`\bf{Thus, u \leq 5.}`
