-3 ≤x<5
x ≥-3 or x<5
x ≥-3 and x>5
x≤-3 and x>5

Answer 1

Open circles mean that the value is not included in your inequality, closed circles mean the value is included.

Answer 2

Therefore the values on your number line can go up to 5, but will never reach 5, and can go down to 3, and will include 3.

Answer 3

Which inequality do you think represents what I just said? :)

Answer 4

x≤-3 and x>5 ? @Jhannybean

Answer 5

d?

Answer 6

not quite.

Answer 7

The values are not going beyond 5, they are going up to 5, meaning 5 is a maximum value.

Answer 8

you can eliminate d, that can't be one of your choices.

Answer 9

also c.

Answer 10

would it be B

Answer 11

Or means there is a space in between the numbers where x can one set of values or the other.

Answer 12

A. says x is less than 5 and is greater than or equal to -3.

Answer 13

ok yeh :)

Answer 14

So what do you think it is? :)

Answer 15

ok wait its either A or B right ?

Answer 16

Mmhmm.

Answer 17

ok b

Answer 18

idk tho

Answer 19

Not quite, remember, the answer "x" lies in between both values, it does not jump from one set to another set. this type of inequality is called a conjunction, and typically connects two sets of values by the word "and"

Answer 20

jeez ok so its A

Answer 21

The other values you have are a disjunction, typically represented by the word "or"

Answer 22

Yes, A. lol

Answer 23

ughhg i picked that one at first but then i went with D instead ughh

Answer 24
