Answer:
is rational number.......
The inequality that represents the domain of the function is 
<h3>How to determine the domain?</h3>
The function is given as:

Set the radicand greater than or equal to 0

Multiply through by 2
x - 20 ≥ 0
Add 20 to both sides
x ≥ 20
Hence, the domain of the function is x ≥ 20

256.5/18= 14.25
(14.25x2)+(18x2)= 64.5m
Write out the slope formula:
m = (change in y) / (change in x)
Here,
m = n-(-9) / (-6-(-2)) = (n+9 / (-4)
Now set this slope equal to -1 and solve the resulting equation for n:
(n+9) / (-4) = - 1, or (n+9) / 4 = 1, or n+9 = 4. Then n = -5.
