Two adjacent, supplementary angles form a

line?

Give me the equations of two lines that have the same slope but are not parallel.

Apinhole camera is made out of a light-tight box with a piece of film attached to one side and pinhole on the opposite side. the optimum diameter d(in millimeters) of the pinhole can be modeled by d=1.9[ (5.5 x 10^-4) l) ] ^1/2, where l is the length of the camera box (in millimeters). what is the optimum diameter for a pinhole camera if the camera box has a length of 10 centimeters

Find the solution(s) to the system of equations. select all that apply y=x^2-1 y=2x-2
