Best ResponseYou've already chosen the best response.0how do u write the interval notation using the union sign

Best ResponseYou've already chosen the best response.0Hmm, those don't look quite right. Here is what I would recomment for the first relationship.\[\large\rm 2y+5\lt 5y1\]Subtracting 2y from each side,\[\large\rm 5\lt 3y1\]Adding 1,\[\large\rm 6\lt 3y\]Divide 3 gives us,\[\large\rm 2\lt y\]

Best ResponseYou've already chosen the best response.0Again, to do it in text, you'll have to google it :) lol In the equation tool, it's the command \cup

Best ResponseYou've already chosen the best response.0no i mean write it in interval notation

Best ResponseYou've already chosen the best response.0Well we're not quite there yet :O Both of your y values look incorrect. The other y interval I think is \(\large\rm y\lt 3\) That's what I'm coming up with at least, hmm

Best ResponseYou've already chosen the best response.0No, neither number is correct :( One sec..

Best ResponseYou've already chosen the best response.0Ya in the first one, it was supposed to be 6, not 6. So that should change it to \(\large\rm y\gt 2\) In the second one, your 6 turned into a 8 halfway through. So fixing that should give you \(\large\rm y\lt 3\)

Best ResponseYou've already chosen the best response.0now finally how do u do the union thingy

zepdrix

Best ResponseYou've already chosen the best response.0\(\large\rm y\lt3 ~OR~ y\gt2\) The word OR means union, as you said :)\[\large\rm y\lt3 ~\cup~ y\gt2\]Let's write the y<3 as an interval.

shreenithaa

Best ResponseYou've already chosen the best response.0so the u is replaced for or?

zepdrix

Best ResponseYou've already chosen the best response.0Yes :) The union symbol and the word OR mean the same thing

Best ResponseYou've already chosen the best response.0i only need the union sign

Best ResponseYou've already chosen the best response.0\(\large\rm y\lt3\) can be written as \(\Large\rm \left(\infty,3\right)\) 3 is the largest value this interval can have. and every number below that should be included in the interval. Does that make sense? :o

zepdrix

Best ResponseYou've already chosen the best response.0oh you don't need the intervals? :D

shreenithaa

Best ResponseYou've already chosen the best response.0nope the intervals have to be as the union sign or something like that

shreenithaa

Best ResponseYou've already chosen the best response.0these are disjunctions so yeah

Best ResponseYou've already chosen the best response.0If we're using the Union symbol, we usually write the inequalities as intervals. So for our problem,\[\large\rm y\lt3 ~OR~ y\gt2\]We would write it as\[\large\rm (\infty,3)\cup(2,\infty)\]
