negative 1 divided by 12 times x squared = y
To find vertex we use formula x= -b/2a
From the given equation a= -1/12 and b =0
Plug in the values in the formula
Now plug in x=0 in the given equation and find out y
So y=0
Hence vertex is (0,0), h=0 and k =0
Focus is (h, k+p)
We need to find out p
We know a= -1/12
p = 1/4a
So focus is (0,0-3) that is (0, -3)
Directrix is y = k - p
We know p = -3 and k=0
y = 0 -(-3) = 3. so directrix is y = 3
Focal width = |4p|
We know p = -3
so it becomes |4(-3)| = 12
Focal width = 12
<span>Divide 800 / 20 = 40,
There will be 40 winners per draw.
800 / 100 = 8, 1% will be 8 people in the draw.
40 / 8 = 5, 5% of winning, 95% of loosing.
Hope this helps.</span>

9514 1404 393
Answer:
a. One solution
Step-by-step explanation:
These are two linear equations with different x-coefficients. They have one solution.
__
<em>Additional comment</em>
If the x-coefficients are the same, the system may have 0 or infinite solutions, depending on the constants. It is not possible for a system of linear equations to have exactly two solutions.
