A.
y + 3 ≥ –1

B.
y + 3 > –1

C.
y + 3 ≤ –1

D.
y + 3 < –1

Answer 1

What do you get when you solve the inequality for choice A?

Answer 2

i really dont know my teacher didn't show me anything.

Answer 3

to solve y + 3 ≥ –1, we need to isolate y

Answer 4

to do that, we undo the +3 by subtracting 3 from both sides

Answer 5

y + 3 ≥ –1

y + 3-3 ≥ –1-3

y + 0 ≥ –4

y ≥ –4

Answer 6

See how I did that?

Answer 7

oh ok

Answer 8

do i do that to every single one

Answer 9

yes, and then graph each solution you get

Answer 10

and compare those graphs to the one given

Answer 11

by 3

Answer 12

Answer 13

what do you mean "by 3"?

Answer 14

do i subtract by 3 on each answer?

Answer 15

yes, you subtract 3 from both sides for each inequality to get 'y' all by itself on one side

Answer 16

okay thanks :)

Answer 17

you're welcome

Answer 18

tell me what you get

Answer 19

i am so confused i got -4 on each one

Answer 20

either im doing them wrong or idk

Answer 21

good, the only difference is the inequality sign

Answer 22

A) is y ≥ –4 while B) is y > –4 for instance

Answer 23

oh so it would be B

Answer 24

are you sure?

Answer 25

y > -4 would have shading to the right of -4

there would be an open circle at -4

Answer 26

ohh i think i got it now

Answer 27

so what's the real answer?

Answer 28

A.....

Answer 29

no

Answer 30

when you solve for y in choice A, you get y ≥ –4

so you would shade to the right and you'd have a closed circle

Answer 31

> or ≥ means you shade to the right

the underline under the inequality sign means you have a closed circle

no underline means you have an open circle
