The numerator factored is (x+9)(x-1)
The denominator factored is (x+1)(x-1)
The x coordinate for the hole comes from the like factor (x - 1).
Set it equal to zero.   x - 1 = 0  so x = 1
Plug the x value into the remaining fraction \frac{x+9}{x+1}
\frac{1+9}{1+1} = \frac{10}{2} =5
The answer is (1,5)

After a 15% increase, a town has 115 people. What was the population before the increase?
Arte-miy333 [17]

Answer:

100 people

Step-by-step explanation:

<em>Population</em><em> </em><em>Of</em><em> </em><em>People</em><em>=</em><em>1</em><em>1</em><em>5</em><em>Percentage</em><em>ncrease</em><em>=</em><em>1</em><em>5</em><em>%</em>

<em>The</em><em> </em><em>New</em><em> </em><em>Population </em><em>corresponds </em><em>to</em><em> </em><em>1</em><em>1</em><em>5</em><em>%</em>

<em>(</em><em>That</em><em> </em><em>is</em><em> </em><em>1</em><em>0</em><em>0</em><em>+</em><em>1</em><em>5</em><em>)</em>

<em>We</em><em> </em><em>want</em><em> </em><em>to </em><em>find</em><em> </em><em>the</em><em> </em><em>popula</em><em>tion</em><em> </em><em>that</em><em> </em><em>corresponds</em><em> </em><em>to </em><em>100%</em><em> </em><em>that </em><em>is </em><em>the</em><em> </em><em>original</em><em> </em><em>population</em><em>.</em>

<em>Therefore</em><em> </em><em>Original </em><em>Population</em><em>;</em>

<em>\frac{100}{115}\times {115}{}</em>

<em>100 \: people</em>
