Write the domain and range of the following relations R= {(1,x), (1,y) (1,z), (2,x), (2,y)​}

Graph the system: f(x)= 3/x-2; f(x)= 1/2x + 2

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?

Rewrite the equation x = 65 - 60p by factoring the side that contains the variable p.
