Decrease of 25% means only 855 people? Okay, so you want to backtrack. If you divide by 25% you’re going to get what it was for a 75% decrease. So divide by .75 instead. 855/.75 = 1140 unemployed residents last month

Answer:
![3+ 2\mathbf{i}](https://tex.z-dn.net/?f=3%2B%202%5Cmathbf%7Bi%7D)
![3- 2\mathbf{i}](https://tex.z-dn.net/?f=3-%202%5Cmathbf%7Bi%7D)
Step-by-step explanation:
<u>Quadratic Equation Solving</u>
We have the equation:
![8x^2-48x=-104](https://tex.z-dn.net/?f=8x%5E2-48x%3D-104)
Divide by 8:
![x^2-6x=-13](https://tex.z-dn.net/?f=x%5E2-6x%3D-13)
Now complete the squares so the left side is a perfect square of a binomial:
![x^2-6x+9=-13+9=-4](https://tex.z-dn.net/?f=x%5E2-6x%2B9%3D-13%2B9%3D-4)
Factoring the perfect square:
![(x-3)^2=-4](https://tex.z-dn.net/?f=%28x-3%29%5E2%3D-4)
Taking the square root:
![x-3=\sqrt{-4}](https://tex.z-dn.net/?f=x-3%3D%5Csqrt%7B-4%7D)
The square root of a negative number is an imaginary number:
![x-3=\pm 2\mathbf{i}](https://tex.z-dn.net/?f=x-3%3D%5Cpm%202%5Cmathbf%7Bi%7D)
Solving for x:
![x=3\pm 2\mathbf{i}](https://tex.z-dn.net/?f=x%3D3%5Cpm%202%5Cmathbf%7Bi%7D)
The solutions are:
![3+ 2\mathbf{i}](https://tex.z-dn.net/?f=3%2B%202%5Cmathbf%7Bi%7D)
![3- 2\mathbf{i}](https://tex.z-dn.net/?f=3-%202%5Cmathbf%7Bi%7D)
Answer:
B. f(x) = -x + 11
Step-by-step explanation:
First if you rearrange the equation you get f(x) = -x + 11, like this:
x + y = 11
Minus x from both sides
y = -x + 11
F(x) and y are interchangeable so we just put f(x) in
f(x) = -x + 11
Each of the graphs are attached and we see that they are the same!
