Answer:
The answer is no solution.
Step-by-step explanation: First, you would add + 12 to both sides of the equation so that you would have 5c + 21 = 5c. Then, you would subtract 5c from both sides of the equation. This would leave you with 21 = 0. Since this is not true, the equation would have no solution.
Answer:
Center is at (0,0)
Step-by-step explanation:
An equation of ellipse in standard form is:

Where center is at point (h,k)
From the equation of
. First, we add 45 both sides:

Convert into the standard form with RHS (Right-Hand Side) equal to 1 by dividing both sides by 45:

Therefore, the center of ellipse is at (0,0) since there are no values of h and k.
Answer: 7
