Question

Given A = {a, b, c} and B={c, a}, which of the following is true?

Answer 1

... the following...? u need to post the rest of the Question dude hey?

Answer 2

Oh I got...but can you help me with this one
D = {x|x is a whole number}
E = {x|x is a perfect square between 1 and 9}
F = {x|x is an even number greater than or equal to 2 and less than 9}

D∩F is {4, 6}.

True
False
I so lost:/

Answer 3

sorry dude, no idea what xIx means or DnF...?

Answer 4

I understand...thanks though:)

Answer 5

if it helps... the perfect squares between 1 and 9 are 1, 4 and 9

Answer 6

Yes, it actually does!!! :D thank you for that

Answer 7

Oh no...still confuse but I will get it:)

Answer 8

D = {x or x is a whole number}
E = {x or x is a perfect square between 1 and 9}
F = {x or x is an even number greater than or equal to 2 and less than 9}

D∩F (intersection of D and F) is {4, 6}.

so D: x = whole number... pretty straightforward
E: x = 1 or 4 or 9
F: x = 2 or 4 or 6 or 8

D∩F (intersection of D and F) = ...?

Answer 9

so it's true??...

Answer 10

i never said that
that was just me decoding the symbols (maybe incorrectly?)
i still don't really understand the question as i'm not sure why D and F would intersect...?
ie they're not equations for lines

Answer 11

Okay...thanks anyway, I really appreciate the effect and no they are not it's talking about operations of unions and intersections of a set

Answer 12

all good, sorry dude, went here http://www.rapidtables.com/math/symbols/Basic_Math_Symbols.htm
and that's what i came up with

Answer 13

Okay:)
