help. just need someone to check. fan and medal

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

47 im stuck, but is 48 right? and maybe help with 49 if u can see the question.

OpenStudy (anonymous):

47 is the first one

OpenStudy (anonymous):

i think

OpenStudy (anonymous):

The first one is A

OpenStudy (anonymous):

The second one is...

OpenStudy (anonymous):

The answer is A, because if you square 5, (so, 2x-7 >= 25), then add 7 to both sides, you get 2x >= 32. Now you need to find a number which will result in 2x always being 32 or greater

OpenStudy (anonymous):

So do 32/2, which is 16 and your answer is x >= 16

OpenStudy (anonymous):

is 48 right

OpenStudy (anonymous):

The second one is correct, because linear equations are (correct me if I'm wrong) always consisting of direct variation

OpenStudy (anonymous):

ok nevermind I was going to help but it looks like @xep is just going to keep telling you the answer before I could, so...

OpenStudy (anonymous):

and can u see 49? bc im confussed on that one too.

OpenStudy (anonymous):

I haven't done variation in forever, so I'm not sure. Might help to show the answers too
