You lost minus when you were adding two equations.
-176= - 22x -12y
<span>144 = 6x +12y
</span>-32= - 16x
x=2
88=11x+6y,
88=11*2+6y
6y=66
y=11
Check:
88=11x+6y=11*2+6*11=88 True
144=6x+12y=6*2+12*11=12+132=144 True

Answer:
The concept which best describes the change of the population is the derivative of 
.
Step-by-step explanation:
Observe that the function describes the amount of rabbits at the time t (in years) but no the rate of change of the population at a given instant. So you have to use the derivative of 
to obtain that rate of change at any instant. For example, if we derivate the function we obtain:
And if we want to find the rate of change at 
years we evaluate
rabbits/year
Answer:
Let width = x
Let length = 1.5x
Area = (length)(width)
Area = 1.5x2
