Answer:
can't answer without the picture because you need the route to know how far.
Answer:
1st option
Step-by-step explanation:
(x²+x-6)/(x-7)≤0
x≤-3
2≤x≤7
These are the solutions you'll find solving the inequation

2/80 is equivalent
you can also just multiply the numerator and denominator to find out what else is equivalent.
We have the equation

Let's complete the square, to do it let's add and subtract 25 on the right side

Now we can have y in function of x

Now we can already identify the vertex because it's in the vertex form:

Where the vertex is

As we can see, h = 5 and k = -2, then the vertex is

Now we can continue and find the focus, the focus is

We have a = 1/20, therefore

The focus is

And the last one, the directrix, it's

Then

Hence the correct answer is: vertex (5, -2); focus (5, 3); directrix y = -7
