Answer:
In the question 4/0, the denominator is zero so it is not a rational number.
Answer:
not really
Step-by-step explanation:
because on the first equation you subtract 5and take to y as a negative and in the second equation 5 goes as a positive at least that is what i think
2n^2-8n=9
divide by 2
2(n^2-4n) =9
add (4/2)^2 =4 to each side completing the square
(n^2-4n+4 ) =9/2+4
(n-2)^2 = 9/2+8/2
(n-2)^2 =17/2
take the square root of each side
n-2 = +-sqrt(17/2)
add 2 to each side
n = 2+- sqrt (17/2)
Answer:2+ sqrt (17/2),2- sqrt (17/2)
