Question

Solve the inequalities -150x ≥ − 2,400 and -336 ≥ − 21y.
x<

y >

Answer 1

x ≤ 16

y ≥ 16

Explanation:

-150x ≥ − 2,400

`\Longrightarrow -(1)/(150) * \left( -150\right) x \leq -(1)/(150) * \left( -2400\right)`

`\Longrightarrow x\ \leq (-2400)/(-150)`

`\Longrightarrow x\ \leq 16`

===============

-336 ≥ − 21y

`\Longrightarrow -(1)/(21) * \left( -336\right) \leq -(1)/(21) * \left( -21\right)y`

`\Longrightarrow 16\geq y`

`\Longrightarrow y\geq 16`
