Below is a proof showing that the sum of a rational number and an irrational number is an irrational number. let a be a rational number and b be an irrational number. assume that a + b = x and that x is rational. then b = x – a = x + (–a). x + (–a) is rational because however, it was stated that b is an irrational number. this is a contradiction. therefore, the assumption that x is rational in the equation a + b = x must be incorrect, and x should be an irrational number. in conclusion, the sum of a rational number and an irrational number is irrational. which of the following best completes the proof? it is the sum of two rational numbers. it is the sum of two irrational numbers. it represents a non-terminating, non-repeating decimal. its terms cannot be combined.

Big points me i'll give braliest in this journal assignment, you will deepen your understanding of what makes a number “rational” or “irrational.” use the following questions to guide your journal response. when writing your response, be sure to use complete sentences and clearly explain your thoughts, correctly using math terms where applicable. how do you decide if a number is rational or irrational? use your own words to describe the thought process you would use to arrive at this decision. look up the definitions of the words “rational” and “irrational” in a dictionary. think about the following questions: how is the definition of the word “rational” related to the mathematical concept of rational numbers? how is the definition of the word “irrational" related to the mathematical concept of irrational numbers

The true statement "if x is a rational number and y is a rational number, then the sum of x and y is a rational number" is often confused with the converse "if the sum of x and y is a rational number, then x is a rational number and y is a rational number." in this case, the converse is not always true. which statement is false? a) if the sum of x and y is a rational number, then x must be a rational number. b) if x = 3.5 and y is a whole number, then the sum of x and y must be a rational number. eliminate c) if x is an even integer and y is an odd integer, then the sum of x and y must be a rational number. d) if the sum of x and y is a rational number, then x may be a rational number or x may be an irrational number.
