Fundraiser The history club is raising money so that they can go on a trip to the Smithsonian Institution in Washington, D. C. They need to raise $1400. They plan on
selling pizzas for $6 each and sandwiches for $4.50 each. An equation that models
this situation is given by 6x + 4.5y = 1400 where x is the number of pizzas sold and
y is the number of sandwiches sold.
a. One of the club members wants to figure out how many sandwiches need to be
sold for different numbers of pizzas. Which variable should the club member
solve for? Solve for the variable.

answer: -8.2562234e+13

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14

and that lightbulb changing party must be freaking lit!

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
