@e.mccormick can you help me on this one?
its c
c
thats eazy afff
O_O um... anyone care to explain their answer?
stop being a showoff it is fun to do stuff like that though
go ahead show off
First, I would find the equation of the line.
@caldwelllayna I want you to explain... cause your an amazing user and theres a mod that will ban u
and you dont deserve it .-.
thanks
@caldwelllayna can you help me on another?
First of all my apologies for not responding to you sooner I was helping my mom with something so you would check each answer and see which one would fit into your graph
that is at least how I do it :)
Actually, it would be D 5x - y greater than or equal to 1 -5x -5x (-y greater than or equal to -5x + 1)/-1 y less than or equal to 5x - 1
^ this kid is confusing me... first said A then now its D
A was a mistake
Hence the reason I deleted my comment
Hence I didn't see that you deleted it
anyone want to help on a second one or no?
ok I will try to help you but I am not an expert at math lol
which of the following inequalities matches the graph?
x < 2 y > 2 y < 2 x > 2
Is it B?
Since it looks like it doesn't have a negative or positive slope :/ idk
If y is > 2 then any y > 2 would be valid. Like this one: |dw:1433365384777:dw|
So it is B?
Is that point, on my pic, in the shaded area of your graph?
no
Then it can't be B.
Is it A? since it has a less than sign and your graph shows a negative point
That would mean any X less than 2 would be valid. On your graph, if you put any value with an x less than 2, is it in the shaded area?
Ah I see what your trying to say... so the answer is a point in the shaded area correct?
Well, the inequality you choose needs to be testable at any point. The point must be valid. There is anothe huge clue. The dashed line is vertical going through what?
What point in what axis does it go through?
i feel dumb so... is the point going through one of the answer choices?
Well, it is a big clue to it.
y axis
No, it never touches the y axis. It crosses the x axis.
Answer is D then thanks
Yah. Things great then x=2 are shaded, so x > 2.
