6x - 7y = 16

Subtract 6x from both sides.

-7y = -6x + 16

Divide both sides by -7

y = 6/7x - 16/7

Answer:

y = 6/7x -16/7

Step-by-step explanation:

6x - 7y= 16

Subtract 6x from each side

6x-7y-6x = -6x+16

-7y = -6x+16

Divide by -7

-7y/-7 = -6x/-7 + 16/-7

y = 6/7x -16/7

A species of fish was added to a lake. The population size P() of this species can be modeled by the following function, where t
____ [38]

Answer:

<em>The initial population size is 500 fish</em>

<em>Population size after 9 years: 1910 fish</em>

Step-by-step explanation:

<u>Mathematical Model</u>

We usually represent real situations as mathematical functions or rules that express the dependency of one variable quantity P with another variable quantity t.

The population size of a species of fish P(x) is modeled by the following function:

\displaystyle P(t)=\frac{3000}{1+3e^{-0.34t}}

Where t is the number of years elapsed since the species was added to the lake.

The initial population size can be found by substituting t for 0:

\displaystyle P(0)=\frac{2000}{1+3e^{-0.34*0}}

\displaystyle P(0)=\frac{2000}{1+3*1}

\displaystyle P(0)=\frac{2000}{4}

P(0)=500

The initial population size is 500 fish

The population size after t=9 years is:

\displaystyle P(9)=\frac{2000}{1+3e^{-0.34*9}}

\displaystyle P(9)=\frac{2000}{1+3e^{-3.06}}

\displaystyle P(9)=\frac{2000}{1.047}

P(9)\approx 1910

Population size after 9 years: 1910 fish
