Answer: Depends on the elephant ;)
Answer:
f(x+5)=3x+16
Step-by-step explanation:
lets name " x+5" T
so f(T)=3T+1
now use "x+5" replace T
now its f(x+5)=3(x+5)+1=3x+15+1=3x+16
5p-9=2p+12
+9 +9
5p= 2p+21
-2p -2p
3p/3=21/3
p=7
A reciprocal just flips the fraction
1. 
2.
3. Before it is flipped it is
but it turns into
