Quizplus · Accepted Answer

The set $A = \{ 7,8,9 \}$ is exactly the same as the set $B = \{ x \mid 7 \leq x \leq 9 , x \in N \}$ because $B$ is defined as all natural numbers $x$ such that $7 \leq x \leq 9$, which are precisely 7, 8, and 9. Therefore, $A$ is a subset of $B$ ($A \subseteq B$), and since they are equal, neither is a proper subset of the other.
