Answer:
line of best fit: y = -2.9114x + 46.569
Step-by-step explanation:
Plugging in your table into Excel, it turns out that y = -2.9114x + 46.569  provides a better fit of the data points into the line.  Please see the attached image for details. 
Hope this helps. 
 
        
             
        
        
        
Answer:
(12,-6)
Step-by-step explanation:
we have
 ----> inequality A
 ---> inequality B
we know that
If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities (makes true both inequalities)
<u><em>Verify each point</em></u>
Substitute the value of x and the value of y  of each ordered pair in the inequality A and in the inequality B 
case 1) (0,-1)
Inequality A

 ----> is true
Inequality B

 ----> is not true
therefore
The ordered pair is not a solution of the system
case 2) (0,3)
Inequality A

 ----> is true
Inequality B

 ----> is not true
therefore
The ordered pair is not a solution of the system
case 3) (-6,-6)
Inequality A

 ----> is true
Inequality B

----> is not true
therefore
The ordered pair is not a solution of the system
case 4) (12,-6)
Inequality A

 ----> is true
Inequality B

 ----> is true
therefore
The ordered pair is a solution of the system (makes true both inequalities)
 
        
             
        
        
        
Answer:

Step-by-step explanation:
To simplify recall exponent rules:
1.	An exponent is only a short cut for multiplication. It simplifies how we write the expression.
2.	When we multiply terms with the same bases, we add exponents.
3.	When we divide terms with the same bases, we subtract exponents.
4.	When we have a base to the exponent of 0, it is 1.
5.	A negative exponent creates a fraction.
6.	When we raise an exponent to an exponent, we multiply exponents.
7.	When we have exponents with parenthesis, we apply it to everything in the parenthesis.
We will use these rules to simplify.
Use rule #3 to simplify inside the parenthesis first.

Now simplify the exponent of 4 using rule 6.
