<u>Recall</u> : If a ≠0  ⇒ a⁰ = 1
Then
Since 6⁸ ≠ 0  ⇒ (6⁸)⁰ = 1  
 
        
             
        
        
        
Answer: 
D)50% of the temperatures are less than 77.5 degrees
Step-by-step explanation:
The correct amount of temperatures that are less than 77.5 degrees is 6/8, or 75%.  So D) is false.
 
        
             
        
        
        
Answer:
y >= 8
Step-by-step explanation:
This equation is written in vertex notation, so we know the vertex is (-5,8). The parabola opens upward because the coefficient of the squared term is positive. Therefore, the vertex is the minimum, meaning all y values will be greater than (or equal to) the y-coordinate of the vertex (which is 8). When we convert this into a mathematical inequality, we get y>=8.
 
        
                    
             
        
        
        
The standard form of a line: Ax + By = C where A, B and C are integers.
Answer:
2x + 3y = -6
-4x + 3y = 12
x - y = 5
 
        
             
        
        
        
Answer:
-79.8
Step-by-step explanation:
The change can be found by subracting the ending distance from the beginning distance.
In this case, its 200.6-120.8= 79.8
It is negative because the distance in the end became lower than the beginning distance. 
Hope this helps!
