Select an ordered pair from the choices below that is a solution to the following system of inequalities: 4x + y > -3 y − 2x < 4 A. (-1, 1) B. (0, 4) C. (-1, 5) D. (-2, 3)

OpenStudy (anonymous):

You can tell from looking at an ordered pair which value is the x value and which is the y, right?

OpenStudy (anonymous):

Uhm i dont know.. im horrible at math

OpenStudy (anonymous):

An ordered pair is written as (x, y) So the first value is x and the second value is y. Understand?

OpenStudy (anonymous):

ok yes..

OpenStudy (anonymous):

Cool, so look at your first choice and figure out what x and y are. Now plug those x and y values in and see if they make the inequalities true.

OpenStudy (anonymous):

A ?

OpenStudy (anonymous):

It would need to be true for both to be a solution. Let me show you a quick example. For the system x+2y >10 2x-y < -8 is the point (-1, 6) a solution? x = -1 and y =6. I'll check the first inequality and get -1 + 2(6) >10 -1 + 12 >10 11 > 10, so cool that's true. Now I'll check the second inequality and get 2(-1) - 6 <-8 -2 - 6 < -8 -8 < -8, which isn't true. -8 equals -8, it isn't less than itself. So the point is not a solution because it's only true for one of the inequalities.

C ?

Hey, yeah. You're gonna either need to show me your work or ask me specific questions. I don't hand out answers. Good luck!

OpenStudy (anonymous):

Hey, by the way, you may have copied this problem onto here incorrectly. One of those symbols is probably facing the wrong way or else is supposed to be like one of these: \[\le ,\ge\] Which would mean "is less than or equal to" or "Is greater than or equal to" respectively. I say that because as it is, this problem has no good answer.

i wrtryed writing them down on paper i dont feel like typing the whole problem i fiqured out its 3 in the morning and i have school in 3 hours im tired and stressed

OpenStudy (anonymous):

none of the above options are correct

OpenStudy (anonymous):

You either copied this problem down, or it is a poorly written problem. There is no correct choice.

OpenStudy (anonymous):

YA THRS NO CORRECT OPTION

OpenStudy (anonymous):

the first equation is supposed to be greather than or equal to 3. idk how to put the dash under the sign @sradha @SmoothMath

OpenStudy (anonymous):

It's okay. It's acceptable to type >= or <= instead.
