Answer:
2x² = -8
x² = -4
The answer is no real solutions (x ∉ R) because a perfect square cannot be negative.
 
        
                    
             
        
        
        
1, both functions are linear
        
             
        
        
        
7.5*.2=1.5 
- 1.5= 6.5 w/ 20% off
6.5*0.0525=0.34125- rounded= .34+6.5=
$6.84
Hope this helps!!!!
        
             
        
        
        
This is a relation but not a function.
Functions must have that there is a unique y for a given x, which clearly doesn't work here because all lines of a given x have 2 y-values. However, it is a relation because there is a given set of points which are defined to be within the set of the ellipse (if it's defined which members of two sets, the range and domain, go together, then you have a relation)
 
        
                    
             
        
        
        
The number of Elrodeo students is 837.
Let the number of students at Hawthorne be x.
"<span>El rodeo has 78 more students than hawthorne</span>"
this means that 
837 = 78 + x
x = 837 -78 = 759
Answer: Hawthorne has 759 students
