Question

A laser is raised 9 in. up of a reflective table and pointed so that the beam hits the table 10 in. from the edge. The laser beam follows a path defined by the absolute value function:
v(j)=45j-10
where v is the vertical height and j is the horizontal position from the edge of the table. Use an absolute value model to find the horizontal position(s) where the laser’s beam is 5 in. above the table.
Ms. Sue please help me out ;(
