Question

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

y >

Answer 1

Answer:

x ≤ 16

y ≥ 16

Step-by-step explanation:

-150x ≥ − 2,400 

$\Longrightarrow -\frac{1}{150} \times \left( -150\right) x \leq -\frac{1}{150} \times \left( -2400\right)$

$\Longrightarrow x\ \leq \frac{-2400}{-150}$

$\Longrightarrow x\ \leq 16$

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

-336 ≥ − 21y

$\Longrightarrow -\frac{1}{21} \times \left( -336\right) \leq -\frac{1}{21} \times \left( -21\right)y$

$\Longrightarrow 16\geq y$

$\Longrightarrow y\geq 16$
