Anew company is purchasing a copier for their office. the table shows the costs associated with each copier. write a system of equations for this situation. then use a graphing calculator to estimate the number of copies that gives the same total cost. copier costs copier initial cost cost per copy a $700 $0.02 b $600 $0.06 let x be the number of copies and y be the total cost of printing x copies. write a system of equations for this situation. copier a yequals= ? copier b yequals= ?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
