Write the standard form of a circle with a center at C(-4, -6) and passes through the point (-1, -2).
1 answer:
Answer:
(x+4)^2+(y+6)^2 = 25
Step-by-step explanation:
The radius squared is equal to the distance between the center and the point
3^2 + 4^2 = 25
We can shift the center like this
(x+4)^2+(y+6)^2 = 25

Answer:
8x^6
Step-by-step explanation:
The answer is A: 5
The y-intercept is when x = 0
<span>3y + 4x = 15
x = 0
3y + 4 * 0 = 15
3y + 0 = 15
3y = 15
y = 15/3
y = 5</span>
