The answer would be 20 because if you multiply the entire equation by five you would get 5n+n=120. Then if you solve that smaller equation it gives you 20.
Given:




To find:
The odd function.
Solution:
If f(-x) = -f(x), then the function is odd.
If f(-x) = f(x), then the function is even.
Option A: 
Substitute x = -x



≠ - f(x)
It is not odd function.
Option B: 
Substitute x = -x

(Since
)
≠ - f(x)
It is not odd function.
Option C: 
Substitute x = -x



≠ - f(x)
It is not odd function.
Option D: 
Substitute x = -x


It is odd function.
Therefore, f(x) = -x is an odd function.
Answer:YOUR ANSWER IS C

Answer:

Step-by-step explanation:
it's simple my dear friend.
first, she runs 3 miles per week.
so in

b is 3. the initial value.
increasement by 20% means she runs 1.2 times than before.

then a=1.2
so we have now:

and we got it!
