Answer:
A
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 2, 3) and r = 3 , then
(x + 2)² + (y - 3)² = 9 ← expand left side using FOIL
x² + 4x + 4 + y² - 6y + 9 = 9 ( subtract 9 from both sides )
x² + y² + 4x - 6y + 4 = 0 → A
Answer:
Factored form: -2(x + 7) = 8, x = -11 (brainliest)?
Step-by-step explanation:
-2(x + 7) = 8
x + 7 = 8 / -2
x + 7 = -4
x = -4 - 7
= -11
