3a - 15 = 27
3a = 42
a = 14
Answer:

Step-by-step explanation:
According to the graph, the y int is at 100
so that is the starting point
Then at 1 it is at 50
is 2 so that means it is reduced by half
Just to make sure,
is also /2 so that means it is the slope
Since it is a decay, the slope has to be less than one so you get the reciprecol of 2 to get....

Answer:
1/5^9
