Question

Check my answer..

Answer 1

Solve the absolute value inequality.

{4x+4/2} <4

{} absolute value

I got x> -3 and x<1

(-infinity sign, -3) u (1,infinity sign)

Answer 2

Thats not right.. The 2 is under 4x+2 not just 2

Answer 3

Okay I didn't get that... I will do it again.

Answer 4

I need another one checked..

Use graph to find the set.
(-infinity sign,-2) n {-5,4)

I have (-infinity sign,4) but I feel like its wrong.

Answer 5

\[\large \frac{ 4x + 4 }{ 2 } < 4 => 2x + 2 < 4\]
\[\large 2x + 2 -2 = 4-2 \]
\[\large 2x = 2 \]
\[\large x = 1\]

Answer 6

Sorry
x < 1

Answer 7

It has to have two answers...

Answer 8

I don't know the second one.. sorry .

Answer 9

Uh okay..

Answer 10

@IrishBoy123

Answer 11

is it this?
\[\large \left |\frac{ 4x + 4 }{ 2 } \right|< 4\]

Answer 12

Yes

Answer 13

*I got x> -3 and x<1*

you're right then

Answer 14

Okay thank you.. What about the other one??

Answer 15

you mean this?
Use graph to find the set.
(-infinity sign,-2) n {-5,4)

Answer 16

Yes

Answer 17

the actual notation matters a lot with this stuff so i am going to have to guess that the first set includes everything from \(\infty\) to -2, and the second contains everything from -5 to 4

and you have to find the intersection which would be from -5 to -2

you do need to be careful with notation though, eg are these real numbers, integers etc?

Answer 18

I thought it might be that (- 5,-2) but my other example did it different..

(-infinity sign,-3) u [-6,1]
Answer--- (-infinity sign,1)

Answer 19

Is this because one problem has the u and the other has n ??

Answer 20

Thank you..
