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.

Step-by-step explanation:

it is the sum of two rational numbers.

the answer would be the last one (constat) she stays at the same rat every two mintues it goes up by 0.4

step-by-step explanation:

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes.
