Answer:
Step-by-step explanation:
8/v=6/v-3
8*(v-3)=6v
8v-8*3=6v
8v-24=6v
+24     +24
8v=6v+24
-6v      -6v
2v=24
v=24/2
v=12  miles /hour
v2=12-3=9 miles /hour ( your friend)

Answer:
Growth when: b>1.
Decay when: 0<b<1.
Step-by-step explanation:
Any function in the form  , where a > 0, b > 0 and b not equal to 1 is called an exponential function with base b.
 , where a > 0, b > 0 and b not equal to 1 is called an exponential function with base b.
if 0 < b < 1.  It is an example of an exponential decay.
The general shape of an exponential with b > 1 is an example of exponential growth.
Hence,
An exponential function is expressed in the form  The relation represents a growth when  b >1 and a decay when 0<b<1.
 The relation represents a growth when  b >1 and a decay when 0<b<1.
