Answer:
x = 5 when y = 12
Step-by-step explanation:
If y is inversely proportional to x, we can say that x1 : x2 = y2 : y1
The order of y2 and y1 respectively are interchanged as y is inversely proportional to x
Now let us simply substitute our known values, and solve for x2;
x1 : x2 = y2 : y1
20 : x2 = 12 : 3
20/x2 = 12/3
12(x2) = 3(20)
12(x2) = 60
x2 = 60/12 = 5

Step-by-step explanation:
Answer with Step-by-step explanation:
We have to prove that
is true for all sets A and B
Let 
Then 
or 
and 
or 
Hence,
Conversely ,Let
Then x belongs to A and x does not belongs to B then
x belongs to A- B
Or x belongs to A and x belongs to B then x belongs to 
Hence, 
Therefore,
Answer:
D
