what you need to tell yourself is this:
what are even integers from 8 to 16 inclusive

- Ms-Brains

if I knew the even intergers I wouldn't be asking lol

well what are even integers

- anonymous

do you know what odd and even numbers are?

- Ms-Brains

Yes

- anonymous

good. so lets list all the integers from 8 to 16
8,9,10,11,12,13,14,15,16

- anonymous

which of these numbers are even

- Ms-Brains

8, 10, 12, 14, 16

- anonymous

hence we call this a set of even integers from 8 to 16.

- Ms-Brains

So A is the answer?

- anonymous

yep!

- Ms-Brains

Thanks so much! :)

do you know how to Simplify [-1/4]

- anonymous

what do you mean?

- Ms-Brains

Which value of m makes this statement true?
80 - 2m <= 8 +3m
A.4
B.7
C.12
D.15

- anonymous

just re-arrange if it were an equal sign
80 <= 8+5m
72 <=5m
so you say to yourself, what number must m be so that 5*m must be larger than 72

- Ms-Brains

512
or
515
Both of them are larger...

- anonymous

you have options for m
A.4
B.7
C.12
D.15

- anonymous

5*4=20
5*7=35
5*12=60
5*15=75

- anonymous

so when m=15, the inequality satisfies

- Ms-Brains

Ohhh, That's how you solve that.. Thanks dude!

- Ms-Brains

Which property is demonstrated?
5+8+15 = 5+15+8?

intersection is the same point so imaginations that you doing a graphs and you try to met at 1 point of 2 line :v

- anonymous

yep good.
the intersection A ∩ B of two sets A and B is the set that contains all elements of A that also belong to B (or equivalently, all elements of B that also belong to A), but no other elements.

- Ms-Brains
