Answer:
x = 2y
x - 8 = y + 6
replace x by 2y in the second equation
2y - 8 = y + 6
y - 8 = 6
y = 14
x = 2*14 = 28

Answer:
23040 bats
Step-by-step explanation:
Let N(t) be the number of bats at time
We know that exponential function

According to question

Where t (in years)
Substitute t=2 and N(2)=180

Substitute t=5 and N(5)=1440

Equation (1) divided by equation (2)

By using the property
Substitute the values of b in equation (1)
Substitute t=9
Hence, after 9 years the expected bats in the colony=23040 bats
Answer:
x = 3
Step-by-step explanation:
3(x - 4) = -3

x-4+4 = -1+4
x = 3
