HELP ASAP PLEASE, APPARENTLY MY ANSWER IS WRONG

[-5,-13]

Step-by-step explanation:

To solve this, start by getting rid of the -1 by adding 1 to 8 now you're left with:

|x - 4| ≤ 9 now you will solve this like a regular absolute value inequality

Because the equation withing the absolute value signs can be negative, you will solve this equation twice, once with a negative answer, and the next time, with a positive answer. However, in order to get a negative answer the sign ≤ needs to be flipped. Now we can solve.

Equation 1:

x - 4 ≤ 9 add 4 to -4 so it cancels out, then add it to 9

x ≤ 13

Equation 2:

x - 4 ≥ -9 add 4 to -4 so it cancels out, then add it to -9

x ≥ -5

Both of these equations can be simplified and turned into one compound inequality:

-5 ≤ x ≤ 13

In interval notation, this would be written as:

[-5,13]
