15/70, first option

Step-by-step explanation:

if you multiply the numerators and denomenators together, you get 15/70. you're able to reduce this, but it looks like the answer doesn't want you to reduce it :)

=======================================================

Explanation:

We multiply the numbers across the top (numerator) to get 3*5 = 15

Then across the bottom (denominator), we multiply the values to get 10*7 = 70

So we get

That's how we end up with 15/70

------------------------------

Extra info:

Note how 15 and 70 have the GCF 5, so we can divide both values by 5

This means 15/70 reduces to 3/14; however, your teacher has decided not to reduce (since 3/14 is not one of the answers). So that means we should stick with 15/70 instead.

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
