{x | x R, x < -2}
{x | x R, x > -2}
{x | x R, x ≤ -2}
{x | x R, x ≥ -2}

Answer 1

{x | x R, x < -2} this one i think

Answer 2

thank you

Answer 3

I think it's this one {x | x R, x ≤ -2}

Does the line (x) start at -2? I'm having a hard time of seeing it.

Answer 4

yes

Answer 5

i need help with this one too please

If a graph of a set has an open circle on 1/2 and an arrow pointing to the right, then which of the following numbers is in the set?


3/8
1/2
5/6

Answer 6

i still say its this one {x | x R, x < -2} cos the circle is open not closed

Answer 7

Well then I think it would be x ≤ -2 as in less and equal to -2

I've no idea what the circle means so I'm guessing you know more about this random :P

Answer 8

If a graph of a set has an open circle on 1/2 and an arrow pointing to the right, then which of the following numbers is in the set?


3/8
1/2
5/6

Answer 9

5/6 i think

Answer 10

Which of the following sets would have a graph that is a closed circle on -4 and an arrow to the left?


{x | x R, x < -4}
{x | x R, x ≤ -4}
{x | x R, x > -4}
{x | x R, x ≥ -4}

Answer 11

{x | x R, x ≤ -4} this one

Answer 12

when ever it says closed circle its always gunna be ≤ sign or this one ≥

Answer 13

How many subsets does the set {1, 2, 3} have?


6
7
8

Answer 14

ok thanks so much this stuff just dosnt make sense to me
