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: 2/3, 1/2, 5/8,7/11
Step-by-step explanation: usually the smaller your denominator is the larger your fraction. You also have to look at the numerator and somewhat visualize what it would look like. Such as 2/3 is larger than 1/2 because 1/2 of 3 is 1.5 so since 2 is larger than 1.5 you can say 2/3 is larger
Hope this helps
D. works because if you work it out that means 2n=140 and then divide by 2 which means n=70 and the other number is 71
Answer:
= 109.5 to the nearest tenth.
Step-by-step explanation:
For this problem, we can move all the X's to one side and all the regular numbers to the other.
7x comes over and become -7x
10 goes over and becomes -10.
5x+7x-7x=-3-10+13+12.
-3-10=-13, which cancels out the positive 13.
-7x+7x=0 which cancels each other out.
Now, 5x=12
Divide each side by 5.
x=2.4 <--- final answer.
