(x - 1)2 + (y + 2)2 =36 Find the coordinates of the centre. What is the radius of the circle? Decide if the point (2,3) is inside or outside the en the following equation of the parabola,

Ithink the answer is b i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
