There are 6 houses on a small street. Each house has
a family with 4 children, 2 cats and a dog.
1. How many children are there living on this street?
2. How many pets are there living on this street?

There are 24 children living on the street. There are 18 pets living on the street.

Step-by-step explanation:

The answer is 24 chilren because you have to multiply the amount of children and the amount of houses in the street. When you do that you get 24.

There are 18 pets living on the street because in total 3 pets are living in EACH house. 6×3=18.

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
