Answer:
D. empty set
Step-by-step explanation:
Each of the operations X-Y and Y-X removes elements that are common to X and Y. The resulting two sets have no elements in common, so their intersection is the empty set.
_____
X -Y = {2, 5, 6}
Y -X = {3, 7, 8}
{2, 5, 6} ∩ {3, 7, 8} = { }
<span>Nate’s method works because multiplication and division are the inverse of each other. This means that when you divide 15 (the dividend) by 5 (the divisor) and get 3 (the quotient), the quotient and the divisor multiplied together are factors of the dividend, which becomes a product.</span>
The answer is d because there is a red underline by your teacher usually that means its the answer
