please help

[flew62999]

need help with another problem

l 2 - x/4 l - 3 greater than or equal to 1

the first part in absolute value...

and can anyone tell me how to write symbols?

 

[ElleHCimaras]

Well, I can at least help with the symbols part...

To do absolute value...look right above your enter key there should be a key that looks like \ . It should also be to the right of the ] key. Use the shift key along with the \ key and you should get |absolute value|

You didn't include instructions, but I would guess that you're supposed to solve the inequality, which I will guess is as follows:

. . . .|2 - (x/4)| - 3 > 1

To solve any "greater than" absolute-value inequality, you split it into two. For instance:

. . . .|x + 3| > 4

. . . .x + 3 > 4 or x + 3 < -4

. . . .x > 1 or x < -7

Follow this procedure with your exercise.

I multiplied each side by 4 to get rid of the fraction to get

8 - 4x - 12 >= 4
-4x >= 8
x >= -2

is this correct?

First, you need to follow the instructions (provided earlier) for this type of inequality. You should not be getting only one inequality as the solution for this type of exercise. Second, you need to recall the rule for flipping the inequality sign whenever you multiply or divide through by a negative.
