Any ideas?

OpenStudy (anonymous):

B?

OpenStudy (skullpatrol):

Nope, try looking at where the graphs intersect.

OpenStudy (anonymous):

A? because they intersect at 7 right?

OpenStudy (skullpatrol):

Nope, what value of y will make y=5 a true statement?

OpenStudy (anonymous):

I'm really confused sorry

OpenStudy (skullpatrol):

No problemo, :-) just answer what does y have to be to make y=5 true?

OpenStudy (justin9529):

D

OpenStudy (skullpatrol):

Is 5=5 a true statement @destinistmyers ?

OpenStudy (anonymous):

yes

OpenStudy (skullpatrol):

Ok, so now you know that the solution MUST have a y value of 5, which answer choice has that?

OpenStudy (anonymous):

D?

OpenStudy (skullpatrol):

That is the correct answer :D

Thank you!
