Question

To solve |3x+2|<4, split the equation into


3x + 2 < 4 and 3x + 2 < -4

3x + 2 < 4 and 3x + 2 > - 4

3x - 2 < 4 and 3x - 2 > - 4

3x + 2 < - 4 and 3x + 2 > 4

Answer 1

Is it 3x + 2 < 4 and 3x + 2 < -4 ?
(The first choice)

Answer 2

need help

Answer 3

Yes

Answer 4

have answer choices

Answer 5

There up there with the question

Answer 6

They're

Answer 7

it's not the first choice. see how the inequality signs point the same way? the inequality signs should point in opposite directions.

Answer 8

do you see why?

Answer 9

Yes, I do

Answer 10

So then it'd be the second choice?

Answer 11

yes

Answer 12

an easy way to do this problem if you have a graphing calculator is to graph y=abs(3x-2)-4 (solve your equation for zero, then put y in instead of the zero)

Answer 13

Ok, I'll try that!

Answer 14

Could you help me with one more question?

Answer 15

sure

Answer 16

but I have a question for you afterward

Answer 17

Ok!

Answer 18

Which domain number causes this relation not to be a function?

R = { (-1, -1), (2, 0), (2, 1), (3, 1), (4, 4) }

-1

zero

Answer 19

how much do you already know about what is and is not a function?

Answer 20

a relation is not a function if it has two y-values for one x-value.

Answer 21

I thought it was 1?

Answer 22

domain is x-values
which x-value appears twice and has two different y-values?

Answer 24

yes

Answer 25

Ok, your question?
