Adebate competition has participants from three different schools: 15 from james elementary, 18 from george washington university, and 12 from the mlk jr. academy. all teams must have the same number of students. each team can have only students from the same school. how many students can be on each team?

The number of students in each team can be : 3

Step-by-step explanation:

Since we have to form teams such that two conditions must be satisfied:

Now on the basis of the above conditions to be satisfied we see that we can form "12 teams" such that each team must have "three students" from three different schools.

Hence, the number of students each team could have is 3.

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
