Question

Which of the values satisfy the following inequality

|x-7.5| ≤ 17

select all that apply.

a. x = 27

b. x = -9

c. x = -10

d. x = 20

Answer 1

So first look at the symbol. It must be less than or equal to 17.

By elimination A is 20.5 which is wrong

B is -16.5 by abs =16.5

C is -17.5 by abs = 17.5

D is 12.5

So B and D are possible solutions..
