Let $x,$ $y,$ and $z$ be points such that $\frac{xz}{xy} = \frac{zy}{xy} = \frac{1}{2}.$ if $y = (1, 7)$, $z = (-1, -7)$, then what is the sum of the coordinates of $x$?

Acylinder with a base diameter of x units has a volume of jxcubic units which statements about the cylinder are true? check all that apply. the radius of the cylinder is 2 x units. the radius of the cylinder is 2x units. the area of the cylinder's base is 200 square units. the area of the cylinder's base is a square units. the height of the cylinder is 2x units. the height of the cylinder is 4x units. mark this and return save and exit next submit
