Question

Solve |x + 8| ≤ 5.


x ≤ –13 or x ≥ –3??

Answer 1

\[|f(x)| \le 5\]
=>
\[-5 < f(x)<5 \]

Answer 2

^ luis is correct :)

Answer 3

\[-5 \le f(x) \le 5 = > -5 \le x+8 \le 5 => -13 \le x \le -3\]

Answer 4

|x + 8| ≤ 5
-5 ≤x + 8 ≤ 5
-5 -8 ≤ x ≤ 5 -8
=> -13 ≤ x ≤ -3

Answer 5

@ChinaGurl ---> This is an AND problem and not an OR problem.

x ≥ -13 AND x≤ - 3 which can be written as above: -13 ≤ x ≤ -3
