If vertex of this parabola is (-5,4) what’s the equation

For this case, we have by definition, that the standard equation of a parabola is:

This equation can also be written in the "vertex form":

Where:

The vertex of the parabola is the point (h, k)

In this case we have:

So:

If a <0 opens down

If a> 0 opens up

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
