The taxes on the house are ​$1200

per​ year, and insurance is ​$320

per year. They are requesting a conventional loan from the local bank. The bank is currently requiring a​ 15% down payment and 3​ points, and the interest rate is​ 10%. The ​ couple's gross monthly income is ​$4950

​a) Determine the required down payment.
The required down payment is ​$nothing
.

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

5 + 8 +7 + 4 + 0 +1 = 25

step-by-step explanation:

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
