A 16. Let x be a rational number and y be an irrational number. Which informal proof uses an indirect method to determine if the sum of an irrational number and a rational number is always an irrational number? O 1. Let +y =. where z is rational 2. y== -x 3. y is irrational, and :-x is rational, which is a contradiction 4. Therefore, the sum is an irrational number O 1. Let +y where z is irrational 2. x==-y 3. x is rational, and =-y is irrational, which is a contradiction 4. Therefore, the sum is a rational number O 1. Let +y=. where z is rational 2. x==-y 3. x is rational, and =-y is rational 4. Therefore, the sum is a rational number O 1. Let +y=. where z is irrational 2. y==-x 3. y is irrational, and =-x is irrational 4. Therefore, the sum is an irrational number
