The relationship between the actual air temperature x (in degrees Fahrenheit) and the temperature y adjusted for wind chill (in degrees Fahrenheit, given a 30 mph wind) is given by the following formula: y = -26 + 1.3x

Estimate the actual temperature if the temperature adjusted for wind chill is -35 degrees Fahrenheit.

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- 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. 3- 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 part b?
