Answer:
12x + 164
Step-by-step explanation:
3x + 103 + 9x + 61
rewrite it
3x + 9x + 103 + 61
add 3x and 9x
12x + 103 + 61
add 103 and 61
12x + 164

Step-by-step explanation:
Answer:
Step-by-step explanation:
Ginny determines that the population is decreasing at an average rate of 3% per year.
So, this is an exponential decay case
Formula :
where a is the amount after n years
a is the initial amount
r is the rate of depreciate
n is the number of years
Now we are given that When she began her study, the frog population was estimated at 1,200.
So, a=1200
r = 3% = 0.03
n =x
Substitute the values in the formula:
Hence function represents the frog population after x years is
g - 4h =1
-2g - 3h+ 8j= 5
