Evaluate the given integral by making an appropriate change of variables. x − 2y 3x − y dA, R where R is the parallelogram enclosed by the lines x − 2y = 0, x − 2y = 10, 3x − y = 1, and 3x − y = 4

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
