Write the absolute value equations in the form |x−b|=c (where b is a number and c can be either number or an expression) that have the following solution sets:
Two solutions: x= 1/2 , x=− 1/3 . All numbers such that x≤−14

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
