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
Answer:
diagonal
Step-by-step explanation:
Answer:
(4,5)
Step-by-step explanation:
The x coordinate moves from 3 to 5 which is +2
The y coordinate moves from 2 to 3 which is +1
We move the point (2,4)
(2+2, 4+1) becomes (4,5)
11 elevenths equals the whole meat loafs 11/11=1
Answer:
x=7
Step-by-step explanation:
4 *(4+x) = 2 * (2+20)
Distribute
16+4x =2*22
16+4x = 44
Subtract 16 from each side
16+4x-16 = 44-16
4x=28
Divide each side by 4
4x/4 =28/4
