Question

anyone up to help a clueless person with a geometry portfolio ??? please ???? attachment included

Answer 1

There's a lot here. Which ones are you referring to specifically?

Answer 2

1 and 2 about subsets for sure

Answer 3

A set is simply a collection of things. With math, those "things" are usually numbers, but sometimes variables could be involved.

A subset is a set that is contained within another set. For example

Let's say we had this set here: {1, 2, 3, 4, 5}

A subset could be {3, 4, 5} because 3, 4 and 5 are all in the set above. Another possible subset is {1, 3, 5} because every number in that smaller set is also in the bigger original set

making sense?

Answer 4

i thought it made sense but then i lost it so its not the middle numbers ?

Answer 5

what do you mean by "middle numbers" ?

Answer 6

sorry nope i read that wrong . i thought you just took three numbers from the set but no i was wrong

Answer 7

I just took numbers that are listed in the set {1, 2, 3, 4, 5}

any numbers will do (as long as they are from the set above)

Answer 8

it could be just 1 number, could be 2 numbers, 3 numbers, etc etc all the way up to all 5 numbers

Answer 9

problem #1 says

which is a subset of {..., -6, -4, -2, 0, 2, 4, 6, ...}

Answer 10

then it list possible answers

choice B is NOT a possible answer. Why not? Because -3 is NOT in the original set. The original set is listing even numbers.

So hopefully you see why {-3} is not a subset of {..., -6, -4, -2, 0, 2, 4, 6, ...}

Answer 11

well yes i see that its not in the first set but the other multi choice dont make sense

Answer 12

which one

Answer 13

A isnt it bc there isnt a 1 in the original set cant be C bc there is no 2.5 and D THERE IS ANO 8 IN THE ORIGINAL SET....RIGHT?

Answer 14

well there is no 8 in {..., -6, -4, -2, 0, 2, 4, 6, ...}

BUT

the dot dot dot tells us to continue the pattern forever. So we will keep adding 2 forever as we list numbers to the right. We can't list them all because they go off to infinity

Answer 15

I didn't know that ...

Answer 16

so even though 8 isn't explicitly written down or shown in {..., -6, -4, -2, 0, 2, 4, 6, ...}

it's actually in the set since we can easily write out more terms

{..., -6, -4, -2, 0, 2, 4, 6, 8, 10, 12, 14, ...}

Answer 17

yeah it's like it trails off...

Answer 18

That's how I see it anyway

Answer 19

so i see that its D bc the pattern continues

Answer 20

yes, it continues on forever

Answer 21

okay i get it thank you

Answer 22

no problem

Answer 23

now that you know about subsets, do you know how to answer #2 ?

Answer 24

yes it C right bc its all states

Answer 25

correct

Answer 26

woo :)

Answer 27

okay I can get the rest.. thank you very much for your help!!!!!!

Answer 28

you're welcome
