use the roster method to write each of the given sets. for some exercises you may need to consult a reference, such as the internet or an encyclopedia. (enter empty for the empty set.)
the set of natural numbers x that satisfy x + 8 = 1

Answer is empty set.

Step-by-step explanation:

Here the given equation is x+8=1

on solving this equation ,we subtract 8 both sides ,we get

x+8 -8 = 1-8

x =-7

here we can see that we have only one value of x which is -7

now lets see the set of natural number

N = { 1,2,3,4,5 } here we can see that natural number starts from 1 that is it does not include negative number therefore -7 is not natural number .

therefore answer for this equation as roster set will be empty set .

step-by-step explanation:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
