Best ResponseYou've already chosen the best response.2Do you have to graph the two to solve for n? Or what further instructions do you have?

Best ResponseYou've already chosen the best response.2Good! That makes it easier. Let's start with the first equation. "2n ≥ 4" Start by trying to isolate n. Do you know how to do that?

Best ResponseYou've already chosen the best response.0i actually already solved them. n ≤ 4 or n < 4. I just don't understand why the back of the book says the answer is only n<4

Best ResponseYou've already chosen the best response.2The first equation has an error. See if you can spot it.

Best ResponseYou've already chosen the best response.2And don't overthink it. You got the more complicated part correct, but missed a...simpler part.

Best ResponseYou've already chosen the best response.0Oh, i typed the equation incorrectly. it's suppose to be 2n≥8 or n+3<7.

Best ResponseYou've already chosen the best response.2Don't apologize, it was actually my mistake. Now, is this one of the problems that the book gives the answer to so you can solve for it and see if you got it right?

Best ResponseYou've already chosen the best response.2That's odd, and I'll explain why. My thought process would be to accept n ≤ 4 as correct, as it already includes all that "n < 4" would contain, plus the addition of the answer also possibly being 4. Now, to check my answer, I'm going to ask some others of their opinion on this.

Best ResponseYou've already chosen the best response.12n ≥ 8 or n+3<7 n < = 4 or n < 4 dw:1440981200481:dw n<4 contains n<= 4 so to avoid redundancy ... the solution set is simply all values less then 4

Best ResponseYou've already chosen the best response.1if you were going to pick all the points in the number line that form a solution ... you would define it as all points less then 4 and be done with the explanation.

Best ResponseYou've already chosen the best response.1in set notation ... i dont think you know set notation if D is contained within A, then the union of A with D, is just A ... since D is already a part of A to start with.
