Begin by multiplying everything by 3 to get rid of the fraction. That gives us 
. The rule is when you divide by a negative, the direction of the sign changes, so we will end up with 
. Because there is a line under the inequality sign, the circle is closed. So your choices are the second, fourth, and sixth.
Answer:
Subsets of the given set = 32
Proper subset of the given set = 31
Step-by-step explanation:
Given set is {18, 8, 14, 9, 6} having 5 elements.
We know number of subsets of a set having n elements are represented by
where n is the number of elements in the set.
Therefore, subsets of the given set =
= 32
Since original set itself is a subset of its own, is not a proper subset.
Therefore, proper subset of a set =
=
= 32 - 1
= 31
