Given A = {x | x < 1}, B = {x | x ≥ 5}, and C = {x | x = 5}, match the following items. 1. B ∩ C {x | x < 1 or x = 5}
2.B C {x | x ≥ 5}
3.A C {x | x < 1 or x ≥ 5}
4.A ∩ B {x | x = 5}
5.A B Ø

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

it would open into a square depending on the type of envelope i’m not sure about the second part
