Answer:
y = 7
Step-by-step explanation:
6y+3=45   (subtract 3 from both sides)
6y = 45 - 3
6y = 42 (divide both sides by 6)
y = 42/6
y = 7

Answer:
Standard equation of this circle is (x +5)² + y² = 9.
Step-by-step explanation:
The equation of a circle with center at (h,k) and a radius of r is:
(x - h)² + (y - k)² = r²
Subtitute the variables with h= -5, k = 0, and r = 3
(x - (-5))² + (y - 0)² =3²
(x + 5)² + y² = 9
