Which of the following inequalities is an algebric expression for the shaded part of the number line?
FIGURE DESCRIPTION: Shaded part is the part on number line from -5 to 3 inclusive
(A) |X| LESS THAN OR EQUAL TO 3
(B) |X| LESS THAN OR EQUAL TO 5
(C) |X-2| LESS THAN OR EQUAL TO 3
(D) |X-1| LESS THAN OR EQUAL TO 3
(E) |X+1| LESS THAN OR EQUAL TO 4
SOURCE OG-12 (#130)
What is asked exactly here?

---------- -5 ----------------- x -------------- 3 -----------------
The question is asking which inequality expresses the region
-5<= x <= 3
|x+1| <= 4
x+1 <= 4 and -x-1 <= 4
x<=3 and x >= -5
-5<= x <= 3
E

Oh!!
So we just need to remove absolute sign and find two values of x that defines endpoints of shaded line.
Never faced this kind of question before, was confused by language
Thanks
