Given statement is "You download 12 new songs to your MP3 player. then you delete 5 old songs."
We have to write each amount as an integer.
Download 12 new songs means you are adding number to your MP3 player so we will use + sign for 12
So the amount in integer form will be +12
Ddelete 5 old songs means you are subtracting number from your MP3 player so we will use - sign for 5
So the amount in integer form will be -5
combining both expressions we can write final statement as:
+12-5
Which can be simplified to +7.
So for the first 8, we need to find the value. The way I would find the value would be to find it's place value. So I know that the 8 is in the millionths period. So the value of the eight would be in the millionths. So I think it would be 8,000,000. So that would be the answer. The 8's value is 8,000,000 because of it being in the millionths period.
Hope that helped! :D
Given:
The graph of an invertible function 
<em> </em>is given.
To find:
The value of 
.
Solution:
We know that, if the graph of an invertible function passes through the point (a,b), then the inverse function 
passes through the point (b,a).
From the given graph it is clear that the graph of the function passes through the points 
.
So, the inverse function must be passes through the point 
.
Therefore, the value of inverse function is 
at 
. So, the value of is .
