Answer:
A subset is when all of the elements in the subset are in the actual set. A proper subset is a subset which the actual set has at least on more element than the proper subset.
Step-by-step explanation:
For example, Set A, {1,2,3} is a subset of B {1,2,3}. But Set C, {1,2} is a proper subset of B. Set {5,8} is a subset of {2,5,8}.
Answer:
x ≥ 10 or x ≤ -8
Step-by-step explanation:
2|x - 1| - 3 ≥ 15
Add 3 to both sides;
2|x - 1| ≥ 18
Divide both sides by 2
|x - 1| ≥ 9 or |x - 1| ≤ -9
x - 1 ≥ 9 or x - 1 ≤ -9
Add 1 to both sides;
x ≥ 10 or x ≤ -8
