The require set (CUD)' and C'nD is {q, r, x, y} and Ø.
<h3>Set theory</h3>
Sets are elements arranged in a specific pattern or way. Given the expression below;
U= {f, k, q, r, s, x, y }
C={f, s,y}
D = {f,x)
CUD is the union of two sets and given as:
C U D = {f, s, y, k}
(CUD)' = {q, r, x, y}
For the set C'nD
C' = {k, q, r,x}
C' n D = Ø.
Hence the require set (CUD)' and C'nD is {q, r, x, y} and Ø.

Mexico could be a nation with no memory and in this way unused all the time. Conventions are strengths of nature, and history is simply a story for excitement, for one cannot learn from it The same histories of debasement, the same stories of achievement, the story of the ones who accomplish enormity somewhere else proliferates.
Z - (-9) is the same as z + 9. Subtracting a negative is the same as adding.
Therefore
17 = z - (-9)
is the same as
17 = z + 9
To get 'z' all by itself, we need to subtract 9 from both sides. We subtract 9 from both sides to undo the "plus 9" occurring to the 'z' on the right side.
17 = z + 9
17-9 = z + 9=9 ... subtracting 9 from both sides
8 = z
z = 8
So the answer is z = 8
---------------------------
Check:
17 = z - (-9)
17 = 8 - (-9) ... replace z with 8
17 = 8 + 9
17 = 17
Answer checks out
Answer:
b and E and c
Step-by-step explanation:
- A is false because some elements have the same image like 2.3 and 2.2 , 2.5 ...
- B is true because the image of an integer remains the same using the greatest integer function. So C is true
- E is true
