Answer:
x=16.5
Step-by-step explanation:
-1/2 on both sides
17-0.5 or 1/2=16.5
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
use the distributive propriety to get 4c -12 = 8
divide both sides by 4 to get c-3 =2
 
        
             
        
        
        
Answer:
Step-by-step explanation:
In each case we find the discriminant b^2 - 4ac.
If the discriminant is negative, we have two unequal, complex roots.
If the discriminant is zero. we have two equal, real roots.
If the discriminant is positive, we  have two unequal real roots.
 #51:  8v^2 - 12v + 9:  the discriminant is (-12)^2 - 4(8)(9) = -144.  we have two unequal, complex roots
#52:  (-11)^2 - 4(4)(-14) = 121 + 224 = 345.  we  have two unequal real roots.
#53:  (-5)^2 - 4(7)(6) = 25 - 168 (negative).  we have two unequal, complex roots.
#54:  (4)^2 - 16 = 0.  We have two equal, real roots.
 
        
             
        
        
        
Answer:



Step-by-step explanation:
From the attachment, we have:



Rotation: 180 degrees clockwise
Required
Find J', K' and L'
When a point (x, y)is rotated 180 degree clockwise, the resulting point is: (-x, -y)
So, we have:
