Answer:
The system of equations is:
x + y = 15
xy = 15
Step-by-step explanation:
solve the first for y and substitute in the second:
y = 15-x
x(15-x) = 15
15x - x� = 15
15x - x� - 15 = 0
-x� + 15x - 15 = 0
x� - 15x + 15 = 0
Answer:
growth
Step-by-step explanation:
This is of the form
y = ab^x where a is the initial value and b is either growth or decay
if b > 1 then it is growth
b <1 it is decay
a = .2
b = 4
Since b>1 it is growth
The answer will be 9 1/12 because if you add them up you get 11/12. So the mixed number would be 9 1/12
7/10 = x/12 which mean you need to multiply each side by 12 to find x. So the answer would be X= 8.4
Then it is likely that the amount of mice will decrease and either keep going down because the organism is eating them off too quickly or stay at a medium rate
