What is the intersection of the three sets: A = {0, 2, 3, 6, 8}, B = {2, 3, 6, 8, 9}, and C = {1, 2, 4, 8, 9}? A. {2, 8, 9} B. {

Answer:
{2,8}
Step-by-step explanation:
This is the same thing as asking what element (in this case what number) is in all 3 sets.
0 isn't in all 3 sets because it isn't in B.
2 is in all 3 sets
3 isn't because it isn't in C
4 isn't in A.
6 isn't in C.
8 is in all 3 sets.
9 isn't in A
So the elements that are in the 3 sets are {2,8}.
The slope is 1/2.
You can figure it out using the rise over run method
Answer:8 and 4. Explanation: Let the 2 numbers be x and y with x > y. ⇒x+y=12→(1)←sum of 2 numbers. ⇒x−y=4→(2)← difference of numbers.

Answer:
x = 8
Step-by-step explanation:
Since the triangle is equiangular then the 3 angles are congruent and of measure 60°.
Equate any of the 3 angles to 60 and solve for x, that is
7x + 4 = 60 ( subtract 4 from both sides )
7x = 56 ( divide both sides by 7 )
x = 8
