Answer:
Step-by-step explanation:
You have a vertex coordinate and 2 points. In order to write the equation for that parabola, you only need the vertex and one point. We will fill in the following work form of the parabola:
, where h and k are from the vertex and x and y are from the point. Filling in:
and
and
and
9 = 9a s0
a = 1.
Now we can write the equation, filling in a, the only unknown we had, which we now know is 1:

Divide 2 by 5 to get 2/5.
Or, divide 20 by 50 to get 2/5.
If the ratio of the numbers is 2:5, you can get 2/5 if you divide them.
If you would like to divide 2/3 by 1/2, you can do this using the following step:
2/3 / 1/2 = 2/3 * 2/1 = 4/3 = 1 1/3
The correct result would be 1 1/3.
