Which of the following is(are) the solution(s) to |x-1|- 8?
O A. x=-7,9
O B. x=7
O C. =7,-9
O D. x=9
SUBMIT

Solutions are -7 and 9

Step-by-step explanation:

⇒ |x-1| - 8 = 0

⇒ ± (x - 1) - 8 = 0

⇒ x - 1 - 8 = 0 and -x + 1 - 8 = 0

⇒ x - 9 = 0 and -x - 7 = 0

⇒ x = 9 and x = -7

square root of 36/6 = 2.449489743
