My answer is D Choose the point which is a solution to the system of inequalities: y _<_ -2x + 3 y < 1/2 x - 4 (2 points) Answer (4, -6) (-4, 6) (4, 6) (-4, -6)

Parth (parthkohli):

How do you think it is D?

OpenStudy (anonymous):

I meant c****

OpenStudy (anonymous):

Sorry, typo

Parth (parthkohli):

How do you think it is C?

OpenStudy (anonymous):

I think in order to balance it, they both have to be positive

Parth (parthkohli):

Do they satisfy both inequalities?

OpenStudy (anonymous):

yes @ParthKohli

Parth (parthkohli):

\[6 \le -2(4) + 3\]\[6<{1\over 2}(4) -4\]Do you think both inequalities are satisfied?

OpenStudy (anonymous):

no

Parth (parthkohli):

Then what do you think is the answer?

OpenStudy (anonymous):

I thought B all along, but now I have to settle on A

Parth (parthkohli):

Do you think that the inequalities are satisfied?

OpenStudy (anonymous):

yes

Parth (parthkohli):

How so? Can you show your work?

OpenStudy (anonymous):

y _<_ -2x + 3 y < 1/2 x - 4 the first has a negative 2, so you want to make both sides even -2 plus 4 would get you your -6 (4, -6)

Parth (parthkohli):

You got it :)

Parth (parthkohli):

Yes - it was A =)

OpenStudy (anonymous):

thank god:)

OpenStudy (anonymous):

Parth (parthkohli):
