The graph below shows the solution to which system of inequalities?

OpenStudy (anonymous):

OpenStudy (cwrw238):

y > x y < 1

OpenStudy (anonymous):

can i ask how did you get that answer.

OpenStudy (anonymous):

A. x 1 and y > x B. y < 1 and y x C. y 1 and y > x D. x < 1 and y x

OpenStudy (cwrw238):

the sloping line is y = x - the shading is above this line - so its > sign the horizontal line is y = 1 and shading below so <

OpenStudy (cwrw238):

sorry i should have guided you through this not just give you the answer

OpenStudy (cwrw238):

so it is y>x and y < 1

OpenStudy (anonymous):

OpenStudy (anonymous):

is it C?

OpenStudy (cwrw238):

i guess it must be but they seem to left < in y 1

OpenStudy (cwrw238):

left < out in y 1

OpenStudy (anonymous):

it wasn't C

OpenStudy (cwrw238):

oh - what was the answer the book gave then?

OpenStudy (anonymous):

it was B

OpenStudy (anonymous):

it's b

OpenStudy (anonymous):

when you have a dotted line it is saying that the solution cannot be on that line

OpenStudy (anonymous):

when you have a solid it mean >=

OpenStudy (anonymous):

dotted line: less than, greater than solid line: less than or equal, greater than or equal

OpenStudy (cwrw238):

right - i missed that!

OpenStudy (anonymous):

thanks for the help.

OpenStudy (cwrw238):

so it should be >= for y x right?

OpenStudy (cwrw238):
