Suppose y varies directly with x. if y=6 when x=2 find x when y=12

Use the knowledge of x- and y- intercepts to choose the correct graph of the equation 3x+6y=6

The ksp expression for the system pbcl2(s) pb+2(aq) + 2 cl-(aq) is: [pbc12][pb+2][2cl-] [pb+2][cl-]2 [pb+2][2cl-]2 [pbcl2][pb+2][cl-]2 [pb+2][2cl-]2[pbcl2]

#1-20 state whether the angles are alternate interior, alternate exterior, vertical, or corresponding angles.
