Step-by-step explanation:
43 Is the solution after adding
I believe your answer is D, because vertical angles are congruent
You have to complete the square of (x²+18x+?) as well as for (y²-36y+?)
You will find: (x+9)² + (y-18)² = 36
& this is the standard equation requested
Answer:
Step-by-step explanation:
2x + 2y = -2
3x - 2y = 12
5x = 10
x = 2
2(2) + 2y = -2
4 + 2y = -2
2y = -6
y = -3
(2, -3)
