When we first learn arithmetic, we focus on working with whole numbers. Then, we extend our
understanding to fractions and negative numbers
In algebra, we transfer these same skills to
expressions involving variables. What elementary
skills have you used so far in this course, and how
have you extended them?

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

a king of hearts and a 2 of spades

answer: 0.11 cents for each egg

find what is a dozen     dozen = 12

you have to divide 1.35 / 12 = 0.1125

0.4 liters = 400 milliliters (multiply the volume value by 1000 and it give you the answer). hope this ! ^-^
