Question

confused....Which of the following represents the solution of x - 8 < -2 in set notation?

Answer 1

{x| x < 6}
{x < 6}
{x| x < -10}
{x < -10}
which one please explain

Answer 2

Soooo if we add 8 to both sides of the inequality, it tells us that x < 6 right? :o But we need that in set notation hmmmm.

So we know it's one of the first 2.

Answer 3

i can only be on the internet till 930 so could you please speed it up

Answer 4

That little vertical bar is very important, it means "such that".
I'll try to break it down so it makes some sense.
{ <-- the beginning of the set bracket, we can read this as "the set of points..."
x
| <-- tells us that certain restrictions are going to be placed on the points, "such that"
x<6 <-- the restriction on our set of points.
}

"The set of all points, x, such that, x is be less than 6."
It's the first one :) The second one doesn't make sense for set notation :D
Hope that helps!

Answer 5

yes thank you!
