Question

Can someone help me with this equation? Equation in comment.

Answer 1

\[ |4x + 3| \le 19 \]

Answer 2

Solve the absolute value inequality

Answer 3

4x + 3 ≤ 19
- 3 -3
4x ≤ 16

Answer 4

That's the first step yes.

4x + 3 >=-19

Is the second step

Answer 5

-head tilt-

4x + 3 ≤ -19?
-3 - 3
4x ≤ -22

Answer 6

Not less than or equal -19. greater than or equal to -19

Answer 7

I don't get it. :c Am I right or wrong?

Answer 8

Wrong.

|x|<=b

is similar to

-b<=x<=b

where b is a non negative real number

Answer 9

whut o3o

Answer 10

\[-19 \le 4x + 3 \le 19\]

Answer 11

Isn't mine right? It's going to equal 5.5 either way.

Answer 12

You're saying it's less than or equal to -5.5
I say it's \[-5.5 \le x \le 4\]

huge difference

Answer 13

I honestly don't even know what it is saying. -nodnod-

Answer 14

Another example:
Do you know the difference between x>5 and x<5

Answer 15

Yes.

Answer 16

Learn these two rules and try to understand them:

if a and b are non negative real numbers, then:

|x| > b

then

x<-b OR x>b



|x| < a

Then

-a < x < a

Answer 17

But. The only answers i'm allowed to choose from are these. :I

Answer 18

x less than or greater to -5.5 or x greater than or equal to 5.5

x greater than or equal to -5.5 or x less than or greater to 4

x less than or greater to -5.5 or x greater than or equal to 4

x less than or greater to -5.5 and x greater than or equal to 4

Answer 19

Are you sure you typed the initial problem correctly?

Answer 20

Solve the absolute value inequality: |4x + 3| \[\ge\] 19

Answer 21

...

Okay. So then it's

4x + 3 >= 19

or

4x + 3 <= -19

Answer 22

4x + 3 >= 19
- 3 -3
4x >= 16
x >= 4

Answer 23

4x + 3 <= -19
-3 -3
4x <= -22

Answer 24

x = -5.5

Now am I right?

Answer 25

Correct phrasing:

x less than or equal to -5.5 OR x greater than or equal to 4

Answer 26

Let's try this one! >:D


Solve the absolute value inequality: |2x - 3| < 5

Answer 27

|2x - 3| < 5
+3 +3
2x < 8
x < 4

Answer 28

50%

Answer 29

|2x - 3| < -5
+3 +3
2x < -2
2x > 2
x > 1

Answer 30

nope. you didn't read what I said. I can't help you if you won't listen to me

Answer 31

What did I do wrong?

Answer 32

|x| < a

-a < x < a

where a is not negative

Answer 33

I don't get it.

Answer 34

using numbers instead of letters:

|x| < 5

Then

-5 < x < 5

Answer 35

But I already told you the answers are only ANDS OR ORS.

Answer 36

-5 < x < 5 means x larger than -5 AND x smaller than 5

I suggest you go read the terminology

Answer 37

They don't teach us that because it isn't basic.

Answer 38

Slaaibak, I came to the same conclusion:
