The vertex of the parabola is at (0,0), and the focus is at (0,-7).
The focus is given by the following values:

h and k represent the x and y values of the vertex. We want to solve for p.
Set the y value for the focus equal to -7:

We know that k = 0, so we can simplify to get p by itself:

Standard form of a vertical parabola is given by the following formula:

Plug in all of your known values into the formula:



The answer is
"y^2 = -28x".
Answer:
1:1.5 or 2:3 or 4:6 or 8:12, etc. is the ratio

Answer:
All of them are true.
Step-by-step explanation:
x^2 y - z / x^2 is true. x^2, when divided by itself, cancels itself out, so the equation that is left is y - z.
For the second one, a/c + b/c is true because when you add a + b = it will change; it will be added together. the remaining c will stay the same, as it is the denominator/the same, so you keep it as it is.
For the final one, you distribute ^2 to (a+b), so they become a^2 + b^2.
This means that all of the statements are true.
