Answer:
Option D (7, -3)
Step-by-step explanation:
We know that the general equation of an ellipse has the form:

Where the point (h, k) are the coordinates of the center of the ellipse
In this case the equation of the ellipse is:

Then 

So The coordinates of the center of the ellipse are (7, -3)
 
        
                    
             
        
        
        
Answer:
D
Step-by-step explanation:
because we know that angle EOD is less the 90 so that means that it is complementary. For AOB it is  the same but we can check by adding 35 plus x plus 90 =180 degrees  so 35+90=125  x=180-125=55 so x=55 and 55 is less then 90  so it is a complementary angle.
 
        
             
        
        
        
Answer: Yes, it is 125%
Step-by-step explanation:
 
        
             
        
        
        
x²(x - 4)(2x + 5) = 0
 x² = 0       or    x - 4 = 0     or        2x + 5 = 0
√x = √0   or          x = 4     or               2x = -5
   x = 0                                                     x =
