Question 10 of 10
Which of the following is(are) the solution(s) to . |x+8|= 1?

Answer 1

The solutions are x = -7 and x = -9

Explanation:

All absolute values are non-negative numbers, so x + 8 will always be greater than 0. This means that |x + 8| = 1 can be represented as x + 8 = 1 AND x + 8 = -1.

x + 8 = 1 ⇒ x = -7

x + 8 = -1 ⇒ x = -9

So the solutions are x equals -7 or -9.
