16 regions do not have this type of website . And , 
fraction of regions do not have this type of website .
<u>Step-by-step explanation:</u>
Here we have , as internet usage grows in a particular country, more and more of its regional governments are placing services online. thirty four out of the fifty regions have web sites that allows residents to file their residents to file their regional income tax online. We need to find how many regions do not have this type of website. what fraction of regions do not have this type of website .Let's find out:
It's given that , thirty four out of the fifty regions have web sites , region which don't have :
⇒ 
⇒ 
So, 16 region don't have this type of website!
Fraction of region that don't have this type of website is :
⇒
⇒
⇒
Therefore , 16 regions do not have this type of website . And , fraction of regions do not have this type of website .
The range is from -3 to ∞

Step-by-step explanation:
The solution of the system of equations is (-3 , -2)
Step-by-step explanation:
Steps for Using Linear Combinations Method)
- Arrange the equations with like terms in columns
- Analyze the coefficients of x or y
- Add the equations and solve for the remaining variable
- Substitute the value into either equation and solve
∵ 3 x - 8 y = 7 ⇒ (1)
∵ x + 2 y = -7 ⇒ (2)
- Multiply equation (2) by 4 to make the coefficients of y are equal in
magnitude and different in sign
∴ 4 x + 8 y = -28 ⇒ (3)
Add equations (1) and (3)
∵ 3 x - 8 y = 7 ⇒ (1)
∵ 4 x + 8 y = -28 ⇒ (3)
∴ 7 x = -21
- Divide both sides by 7
∴ x = -3
Substitute the value of x in equation (2) to find y
∵ x + 2 y = -7 ⇒ (2)
∵ x = -3
∴ -3 + 2 y = -7
- Add 3 to both sides
∴ 2 y = -4
- Divide both sides by 2
∴ y = -2
The solution of the system of equations is (-3 , -2)
