Step-by-step explanation:

The first step is to setup the division problem

3x - 1 \sqrt{9 {x}^{2} }  - 6x + 2

Next we divide

9 {x}^{2}  \div 3x = 3x

So now we have to multiply 3x by 3x and -1 by 3x

3x \times 3x = 9 {x}^{2} \\    - 1 \times 3x =  - 3x

Then

\:  \:  \:  \: 9 {x}^{2}     - 9 {x}^{2} = 0

- 6x + 3x =  - 3x

Now we divide

- 3x \div 3x =  - 1

Now multiply

- 1 \times  - 1 = 1

Now we

- 3x + 3x = 0 \\ 2  - 1 = 1

So the answer is

3x-1 Remains 1/3x-1

3x - 1 +  \:  \frac {1}{3x - 1}

between 1995 and 2006, the population of samburg, usa(in thousands) can be modeled by f(x) = 0.35x(squared) - 2.1x+15.8 where x=
Juli2301 [7.4K]
\bf f(x)=0.35x^2-2.1x+15.8\qquad 
\begin{cases}
x=\textit{year since 1995}\\
f(x)=\textit{population amount}
\end{cases}

the equation is a quadratic one, and it has a positive coefficient on the leading term, meaning, is opening upwards, so it has a "burrow" for the vertex.

the minimum or lowest point for a quadratic opening upwards is, well, the vertex point :),   the "x" value is the year, the "y" or f(x) value is the population, we're asked for the year, or the x-coordinate of the vertex

well   \bf \begin{array}{llll}
f(x)=&0.35x^2&-2.1x&+15.8\\
&\quad \uparrow &\quad \uparrow&\uparrow \\
&\quad  a&\quad  b &c
\end{array}
\\\\
