Answer: h(x) =
<u>Step-by-step explanation:</u>
6x + y = 4x + 11y
<u> -y </u> <u> -y </u>
6x = 4x + 10y
<u>-4x </u> <u>-4x </u>
2x = 10y
<u>÷10 </u> <u> ÷10 </u>
= y
Since "y" represents h(x), then h(x) =
We know that the population is declining at a rate of 14% per year.
The expression is:
N ( x ) = 206 * ( 0.86 ) ^ x
where x stays for years.
If we want to find the rate at which the population is declining per month we have to find:
And 0.9875 ≈ 0.99
There are 12 months in a year so the exponent is: x/12
Answer:
b. ( .99 ) ^ x/12
