Answer:
D) 20
%
Step-by-step explanation:
Convert the fraction to a decimal, then multiply by 100.
Answer:
Standard form is Ax+By=C
move the x-value to the left: 1/2x+y=4
1/2x+y=4
or multiply by 2x+2y=8

Answer:
Domain of the function is Option 1. (-∞,1)∪(1,∞).
Step-by-step explanation:
In the question two functions have been given as
f(x) = (x-1)/2x and g(x) = (x-1)/x
Now we have to find a function defined as (f Ф g(x))
We put the value of g(x) in f(x) to find a new function defined as fФ(g(x))
⇒ fФ(g(x)) = ![\frac{(\frac{x-1}{x}-1) }{2(\frac{x-1}{x})} \\](https://tex.z-dn.net/?f=%5Cfrac%7B%28%5Cfrac%7Bx-1%7D%7Bx%7D-1%29%20%7D%7B2%28%5Cfrac%7Bx-1%7D%7Bx%7D%29%7D%20%5C%5C)
Now we multiply numerator and denominator by x.
fФ(g(x) = ![\frac{x-1-x}{2(x-1)}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-1-x%7D%7B2%28x-1%29%7D)
= ![-\frac{1}{2}(\frac{1}{x-1})](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B2%7D%28%5Cfrac%7B1%7D%7Bx-1%7D%29)
The function is defined only if (x-1)>0 ⇒ x >1
and (x-1)<0 ⇒ x <1
So the domain will be the combined set of ( 1,∞) and (-∞,1) or (1,∞)∪(-∞,1).
