Answer:
Step-by-step explanation:
m (x) = (x+ 5) / (x -1) and n(x) = x - 3.
Hence
but n is a function and n = x-3. Now, replace value of n on m (n)
simplify it
since (m . n) (x) is a fraction function, its domain will be all x such that the denominator is NOT 0. That is
among options, only C has the same denominator with 
Hence their domains are the same.
Answer:
The value of x° = 134°
Step-by-step explanation:
Given the angles of a quadrilateral
We know that the sum of interior angles in a quadrilateral is 360°.
so
100° + 51° + 75° + x° = 360°
226° + x° = 360°
subtracting 226° from both sides
226° + x° - 226° = 360° - 226°
x° = 134°
Therefore, the value of x° = 134°
VERIFICATION:
100° + 51° + 75° + 134° = 360°
360°= 360°
4/5 - 1/6
= 24/30 - 5/30
= 19/30
