What is 20/15 simplified? 

20/15 is an imporoper fraction which means that numerator is larger than the denominator

It can be further simplified

fractions can be simplified by finding the highest common factor for both 15 and 20 and dividing the numerator by the highest common factor

factors for 15 and 20 are as follows

15 - 1,3,5,15

20,-,1,2,4,5,10,20

the greatest common factor is 5

so divide both by 5

this can be written as a proper fraction

in 4/3 there's one whole number and 1/3 remaining

so anwer is

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
