A(2,0)B(4,0)C(5,-2)D(1,-2) Which of the following is the image of A after a rotation of -90° about the origin? (0-2)
(0,2)
(-2,0)

Add 1/7 + -1/7 your answer should be reduced to its smallest form and should not be an improper fraction

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?

Plzzz answer both questions and i will give you 100 points
