The answer is 10x - 1380m + z
The mixed number to 18/8 is 2 and 1/4
To find this out you multiply 8 to get to 18, yet 8 only goes to 16 before going over 18, so 8 can multiply 2 times.
The 2 will be your whole number
and since there is 2 numbers left (18-16=2) that would be the numbers left over giving you 2 2/8.
yet the 2/8 can be simplified to 1/4 giving you 2 1/4 as your answer.

Answer:
0.65
Step-by-step explanation:
In order to get a percent, you times a 100 to the number. In order to find the number, you have to divide it by a 100, leaving 0.65
Hope this helps!
I'm pretty sure the answer is D, if not C.
One to one or injective means that each x in the domain maps to a unique y, i.e. the function preserves distinction.
y=(x-1)/(3x+3) is one to one. We can solve for x:
3xy + 3y = x - 1
3y + 1 = x - 3xy = x(1-3y)
x = (3y+1)/(1-3y)
That proves it's one-to-one; for each y we get one x.

That's also one to one,


That's the proof.

That's Not one-to-one
because f(-x)=f(x). We only need a single counterexample; f(1)=7/4, f(-1)=7/4

That's one-to-one, textbook case

That's not one-to-one because the fourth power dominates so this will be sort of parabola-ish, repeating the same big positive values for a negative and positive x.
