Make x the subject of the formula where x is positive <br> b= x -6 / x + 2
Anna007 [38]

Answer:

b =  \frac{x - 6}{x + 2}  \\ b(x + 2) = x - 6 \\ bx + 2b = x - 6 \\ bx - x =  - 6 - 2b \\ x(b - 1) =  - 2(3 + b) \\ x =  \frac{ - 2(3 + b)}{b - 1}

Answer:

Expected population in 2015: 19,152.58 or 19,000 people

Step-by-step explanation:

Given the decreasing rate of 2.5% per year, and a population of 28,000 in the year 2000:

We can solve for the rate of decrease by using the formula:

A = a(1 - r )^{t}

where:

A = population by year 2015

a = initial population (in year 2000) = 28,000

r = rate of change (decrease by 2.5% annually or 0.025)

t = time (in number of years) = 15

Plug in these given values into the formula:

A = a(1 - r )^{t}

A = 28,000(1 - 0.025 )^{15}

A = 28,000(0.975)^{15}

A = 28,000(0.684)

A = 19,152.58 or about 19,000 people in 2015
