Answer:
The center is (7,-4) and the radius is 3
Step-by-step explanation:
(x – 7)^2 + (y + 4)^2 = 9
The equation of a circle can be written as
(x – h)^2 + (y - k)^2 = r^2
where (h,k) is the center and r is the radius
Rewriting the original equation
(x – 7)^2 + (y - - 4)^2 = 3^2
The center is (7,-4) and the radius is 3
Answer:
B taken the test before
Step-by-step explanation:
Answer:
x = -2 or x = -3
Step-by-step explanation:
Solve for x over the real numbers:
x^2 + 5 x + 6 = 0
The left hand side factors into a product with two terms:
(x + 2) (x + 3) = 0
Split into two equations:
x + 2 = 0 or x + 3 = 0
Subtract 2 from both sides:
x = -2 or x + 3 = 0
Subtract 3 from both sides:
Answer: x = -2 or x = -3
