Answer:
The answer is a = 1/4 , b = 0 and c = 5
Step-by-step explanation:
∵ 1/4 x² + 5 = 0 is a quadratic equation
∵ ax² + bx + c = 0 is the general form of the quadratic equation
∴ a = 1/4
∴ b = 0
∴ c = 5
Answer:
Step-by-step explanation:
Divide both sides by 4x
The equation of a circle is:
(x - h)² + (y - k)² = radius²
where (h, k) is the center of the circle.
Your center is (- 2, - 7).
Your radius is √81 = 9
