solve y-2x=8 2y+2x=40
Is this all one question?
if y-2x=8 is a seperate question it would be y = 2x + 8
@undeadknight26 Can you help me?
The domain of the following relation: R: {(3, -2), (1, 2), (-1, -4), (-1, 2)} is {-1, 1, 3} {-1, -1, 1, 3} {-4, -2, 2, 2} {-4, -2, 2}
-1 1 3. first one...remember the domain is the x and when you are listening them you do not double list.
The range of the following relation: R: {(3, -2), (1, 2), (-1, -4), (-1, 2)} is {-1, 1, 3} {-1, -1, 1, 3} {-4, -2, 2, 2} {-4, -2, 2}
How about this one? @undeadknight26
YOu try this one i said that to domain is the first letter than what is the range?
x is the first letter
yes as i said before the x and the domain is the same.
Is it the second one?
please start up another question if you have more questions or email me.
it just says solve using subsitution method y-2x=8 2y+2x=40
then they are separate questions.
so how do i solve it
You are solving for y right?
yes
0037109 i cannot email to you because it is not a valid username...please start your own question.
So we can put it into: y = 2x + 8 /2 /2 y = (x + 8) i believe this is how you answer it.
Are we still solving for y for the second one?
yes
well then i am assuming: 2y = 2x - 40 /2 /2 2y = x - 20 /2 /2 y = x - 10? let me double check.
No apparently the answer is y = 20 -x
I have no idea how to do that srry lol...unless 2y = 2x - 40 /2 /2 /2 y = x - 20...
I hope i helped.
