Which of the following ordered pairs is included in the solution set of the system, y < 2 - 2x and y > 2x -3? A. (0, 0) B. (3, 4) C. (4, 0) D. No Solution

OpenStudy (anonymous):

I think it's A. Am I right

OpenStudy (kinggeorge):

yes again.

OpenStudy (anonymous):

thnk u.. I have one more. :)

OpenStudy (kinggeorge):

sure thing.

http://roads.advancedacademics.com/contentserver/content/roadssection/277506/questions/6hw4/6hw4graph_q6.bmp Which one of the following is a solution for the system graphed? A. (-4, 2) B. (3, 2) C. (0, 0) D. No solution

OpenStudy (anonymous):

I think it's D.

OpenStudy (kinggeorge):

Which area of the graph is a solution?

OpenStudy (anonymous):

thts the thing. From wat I know: |dw:1328244215729:dw| On a graph means tht it's no solution

OpenStudy (kinggeorge):

I'm asking since one of the points is in the blue region, one in the white, and one in the red. Intuitively, my instinct would be to say (0, 0) is correct since it's in the white region, but without further context, I don't know for sure.

OpenStudy (anonymous):

Okay now on this graph these two lines represent the no solution. So I would say it doesn't matter what those other shades are all I see it s no solution graph.

OpenStudy (kinggeorge):

It seems to me as if the white region is the area which has a solution unless I'm misunderstanding the problem. In that case (0, 0) or C should be correct. If the point must actually be on one of the lines, then it would be no solution.

OpenStudy (anonymous):

But what region is the (0,0) in?....the no solution area.

OpenStudy (kinggeorge):

So the white area is the no solution area?

OpenStudy (anonymous):

yes it is because it doesn't have any color.

OpenStudy (anonymous):

the coordinates are suppose to be in the color area.

OpenStudy (kinggeorge):

in that case, both (-4, 2) and (3, 2) should be solutions since they lie in the colored regions

OpenStudy (kinggeorge):

(-4, 2) in the blue region, and (3, 2) in the red.

OpenStudy (anonymous):

okay well idk how to explain it but I got the answer right bcuz i got 100% on tht assignment. so thnk u very much
