A point, W, is graphed at (0, 5). Choose the coordinates of a shape that can be rotated about the y-axis to create a cone. (5 points) Choices:
a) X (0,0) and Y (0,3)
b)X (0,0) and Y (3,0)
c) X (0,0) and Y (0,-3)
d) X (0,0) and Y (0,-5)

What number should be added to both sides of the equation to complete this square? x^2-10x=7
