Answer:
<h2>(20,-10)</h2>
Step-by-step explanation:
<u><em>iI we substitute (20,-10) into the two inequalities ,we get</em></u> :
• 8×(20) + 6×(-10) = 100 and 100 > 24
• (-20) + 4×(-10) = -60 and -60 < -16
Then
(20,-10) falls into the solution of the system of inequalities :
8x + 6y > 24
-x + 4y < -16
I think it’s A it may be C but I’m pretty sure it’s A
