I need help ...!! Select an ordered pair from the choices below that is a solution to the following system of inequalities: 3x – 4y > 7 y < 2x + 3 a. (3, -3) b. No solution c. (-4, -1) d. (6, 3)
Dear Jakk, Substitute the given answers into both inequalities. A solution would make both inequalities true.
For example, using the answer to (a): 3(3) - 4(-3)>7 9+12>7, so this point works in the first inequality. Now try it in the secone inequality.
so it would be like 3 < 2(-3) + 3 3<-6+3 right ?
Nope. For answer (a) x = 3 and y=-3. You substituted incorrectly.
-3<2(3)+3 -3<6+3 like this ?
Great! Looks like you found your solution. Answer (a) makes both inequalities true. I'm signing off. Good luck with your math assignment.
