Answer:
C) (x,y) -> (-x,-y)
Step-by-step explanation:
This is the answer because the graph was flipped. If you look a the x point, it is in the same number, but the number is negative, and this is the same for the y point. hope this helps
 
        
             
        
        
        
Answer:
-18
Step-by-step explanation:
Left Hand Side = -2(7a + 9b) = -14a - 18b
Comparing it with Right Hand Side, ?  = -18

Answer:<em>
 </em><em><u>
w =(-40-√4320)/-34=(20+6√ 30 )/17= 3.110
</u></em></h2><h2><em><u>
 w =(-40+√4320)/-34=(20-6√ 30 )/17= -0.757</u></em></h2>
Step-by-step explanation:  The prime factorization of  4320   is
   2•2•2•2•2•3•3•3•5  
To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. second root).
√ 4320   =  √ 2•2•2•2•2•3•3•3•5   =2•2•3•√ 30   =
                ±  12 • √ 30
  √ 30   , rounded to 4 decimal digits, is   5.4772
 So now we are looking at:
           w  =  ( -40 ± 12 •  5.477 ) / -34
Two real solutions:
 w =(-40+√4320)/-34=(20-6√ 30 )/17= -0.757
or:
 w =(-40-√4320)/-34=(20+6√ 30 )/17= 3.110

Answer:
Domain: 
[-5,-2) U (-2,3.5) U (3.5,5]
Range:
[-3 0) U (0,5]
It is not a function because x = 1 has two different outputs (3 & 5)
