Answer:
vertex at (1, -3)
Step-by-step explanation:
When x = 0
y² + 6y + 1 = 0
y² + 6y + = -1
y² + 6y + 9 = -1 + 9
(y + 3)² = 8 or (-y - 3)² = 8
y + 3 = √8 or -y - 3 = √8
y = - 3 +√8 or y = -3 - √8
(0, - 3 +√8) and (0, -3 - √8)
The mid point between these two is the average
y = ( - 3 + √8 + -3 - √8) / 2 = - 3
y² + 6y + 8x + 1 = 0
(-3)² + 6(-3) + 8x + 1 = 0
9 - 18 + 1 = -8x
- 8 = -8x
x = 1
Answer:
C = 28.048
Step-by-step explanation:
Circumference = 2pi(r)
Area = pi(r)^2
62.6 = pi(r)^2
r^2 = 62.6/pi
r^2 = 19.926
r = 4.464
Therefore, circumference = 2pi(4.464)
= 28.048
Answer:
all done bud, I'm just here for the extra points :D
Add the two angles and set them equal to 180, them solve for x
Answer: since the 5 is a negative you are subtracting it from 3
so 3 +(-5) is actually 3-5. which = -2
