Ms-Brains
  • Ms-Brains

well what are even integers
anonymous
  • anonymous
do you know what odd and even numbers are?
Ms-Brains
  • Ms-Brains
Yes
anonymous
  • anonymous
good. so lets list all the integers from 8 to 16 8,9,10,11,12,13,14,15,16
anonymous
  • anonymous
which of these numbers are even
Ms-Brains
  • Ms-Brains
8, 10, 12, 14, 16
anonymous
  • anonymous
hence we call this a set of even integers from 8 to 16.

Which value of m makes this statement true? 80 - 2m <= 8 +3m A.4 B.7 C.12 D.15
anonymous
  • 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
  • Ms-Brains
512 or 515 Both of them are larger...
anonymous
  • anonymous
you have options for m A.4 B.7 C.12 D.15
anonymous
  • anonymous
5*4=20 5*7=35 5*12=60 5*15=75
anonymous
  • anonymous
so when m=15, the inequality satisfies
Ms-Brains
  • Ms-Brains
Ohhh, That's how you solve that.. Thanks dude!

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
  • 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.
