I'm not 100% sure what you're asking, but i think it wants:

50,000 + 25,000 = 75,000 - so B is the answer

to do it you basically just round the number to the nearest 1000 and add

If A c B and A N B= • then which of the following can be concluded about the sets A and B!

Sergio [31]

Step-by-step explanation:

Set A is a subset of set B if all the elements of A are also the elements of Set B.. (common element)

The above set have 0 common elements so.. if there is no common element and are subsets then it means that there arent any elements in both the sets

so, the answer for the question would be "both the Sets A and B are the empty sets"

If F (7) 22, Then F(f-1(22))

jeka57 [31]

Answer:

$\boxed{\boxed{f(f^{-1}(22))=22}}$

Step-by-step explanation:

$\text{If we have}\ f(x)\ \text{and}\ f^{-1}(x),\ \text{then}\\\\\text{if}\ f(a)=b,\ \text{then}\ f^{-1}(b)=a.\\\\\text{Therefore, if}\ f(7)=22,\ \text{then}\ f^{-1}(22)=7.\\\\f(\underbrace{f^{-1}(22)}_{=7})=f(7)=22$
