     • time
     • rate
     • distance
   • Work problems
     • Ex. 1 job/ time to do alone* time on job + 1 job/time to do alone*time on job = 1 job
     • how long it takes to do one job

     • subtracting rational expressions
     • simplifying rational expressions
   • Restrictions
     • they come from the denominator
     • there can be more than one

6. Lesson 1

   • Direct variation
     • directly varies
     • directly proportional
     • Ex. p=kq
