Marcelina uses a blend of white corn and yellow corn to make tortilla chips at her restaurant. She needs to buy 50 kg of corn in total for her next order. White corn costs $0.30 per kilogram, yellow corn costs $0.15 per
kilogram, and she wants to spend
$12 total.
Here's a graph that shows system of equations for this scenario is where x is the amount of white corn she buys
and y is the amount of yellow corn she buys.

THE ANSWER IS A: Marcelina spends the intended amount of money and buys the intended amount of corn

Ya welcome babes :)

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

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
