2. 428.4
3. i don’t remember how to do the last one.
The answer is because you have to use what you have to subr35x+50y
Answer:
Irrational number
Step-by-step explanation:
The number 1.8 isn't repeating so it wouldn't be a repeating rational number.
Answer:
B. f(x) domain: x ≥ 1
f–1(x) range: y ≥ 1
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
Because the two functions are inverse to each other, so we all know that the domain of f(x) will be the range of and the range of f(x) will be the domain of
As can be seen from the attached photo,
f(x) extends to the right of x=1, so its domain is x ≥ 1.
<=> range is y≥ 1.
Therefore, we choose answer B
Hope it will find you well.
