Answer:
x = 1 and y = 11
Step-by-step explanation:
To start, let's substitute in y into the first equation. We will get 5x + 3 (3x + 8) = 38. Now, distribute the 3 in the 2nd term to get 5x + 9x + 24 = 38. Add like terms to get 14x + 24 = 38, and subtract 24 from both sides to get 14x = 14. Now, divide both sides by 14 to get x = 1. Plug this back in to get that y = 11.
Answer:
(x+9)^2+(y+6)^2=36
Step-by-step explanation:
The equation of a circle is (x-h)^2+(y-k)^2=r^2 where (h,k) is the given center and r is the radius of the circle.
Given a center of (-9,-6) we have (x+9)^2+(y+6)^2=r^2 so far.
Since the diameter is 12, half of that is the radius which is 6, so the equation of the circle is (x+9)^2+(y+6)^2=36 (as 36 is 6^2)
