For U= (2,3,4,5,6,7,8), X=(2,3,4,5), state X'=
tatiyna
Answer:
X' = {6,7,8}
Step-by-step explanation:
X' is the set that contains the elements that are in set U bot NOT in set X.
Step-by-step explanation:
3x+5=44
3x=44-5
3x=39
x=39÷3
x=13
Answer:
The sum of a rational number and an irrational number is irrational." By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats.
Step-by-step explanation:
However, if the irrational parts of the numbers have a zero sum (cancel each other out), the sum will be rational. "The product of two irrational numbers is SOMETIMES irrational." Each time they assume the sum is rational; however, upon rearranging the terms of their equation, they get a contradiction (that an irrational number is equal to a rational number). Since the assumption that the sum of a rational and irrational number is rational leads to a contradiction, the sum must be irrational.
One number is equal to the square of another. find the numbers if both are positive and their sum is 930.
