Select the procedure that can be used to show the converse of the Pythagorean theorem using side lengths chosen from 6 cm, 8 cm, 9 cm, and
10 cm.
O A. Knowing that 62 +82 - 10draw any two of the sides with a right
angle between them. The third side will fit to form a right triangle.
O B. Knowing that 62 +82 > 92, draw the 6 cm side and the 8 cm side
with a right angle between them. The 9 cm side will fit to form a
right triangle
O C. Knowing that 82 +92 + 102 draw the 8 cm side and the 9 cm side
with a right angle between them. The 10 cm side will fit to form a
right triangle.
D. Knowing that 62 +82 = 102 draw the 6 cm side and the 8 cm side
with a right angle between them. The 10 cm side will fit to form a
right triangle

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

the answer would be c
