OpenStudy (acxbox22):

which compound inequality do you think it represents?

OpenStudy (anonymous):

its either a or b

OpenStudy (anonymous):

because they are connected together

OpenStudy (babynini):

Perfect! So when the black dots are filled in, it means that the numbers are included. Does a or b represent that 10 and 50 are included?

OpenStudy (acxbox22):

okay so the graph says that everything greater than 10 and inculding 10 all the way to 50 inclusive so which inequality matches that statement? and yes it is either A or B

OpenStudy (anonymous):

well B and D are included

OpenStudy (anonymous):

is it A ?

OpenStudy (babynini):

It would be A if the dots weren't filled in, like this.|dw:1430958892823:dw|

OpenStudy (acxbox22):

A is not included

OpenStudy (acxbox22):

OpenStudy (anonymous):
