The standard equation for an ellipse is
where
(h,k) = coordinates of the center
a, b = semi-major and semi-minor axes
Refer to the figure shown below.
The center of the ellipse is at (0,0).
Therefore, h=0, k=0.
One focus is at (12, 0)
Therefore
c = 12
One directrix is at 14 1/12 = 169/12.
Because the directrix is located at x = a²/c, therefore
a²/12 = 169/12
a² = 169/144
a = 13
Because c² = a² - b², obtain
b² = a² - c²
= 169 - 144 = 25
b = 5
Answer:
The equation for the ellipse is
If I remember correctly it should be B because every input has to have 1 output. I apologize if it’s wrong ( I haven’t had those problems since 8th grade I’m currently in 10th)

Answer:
x = -2
Step-by-step explanation:
-6x -2x = 16
Combine like terms
-8x = 16
Divide each side by -8
-8x/-8 = 16/-8
x = -2
Answer:
Step-by-step explanation:
f(x) = 6x - 4
when x < 2
and
f(x) = 2x + 4
when x > 2
When x < 2 ;
f(x) < 6(2) - 4
f(x) < 8
When x > 2 ;
f(x) > 2(2) + 4
f(x) > 8
