−
x
Step-by-step explanation:
Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=9x+56−x f - 1 ( x ) = 9 x + 5 6 - x is the inverse of f(x)=6x−5x+9 f ( x ) = 6 x - 5 x + 9 .

I dont give you the answer right away so you will read what i write and fully understand :D
Step-by-step explanation:
We are picking 3 balls from 30 balls, so its C(30,3) because the order of picking the balls doesnt matter. We also need to pick 2 balls from 20 balls, which is C(20,2). So the answer is C(30,3) * C(20,2).
Answer:
y=0.5x-3
Step-by-step explanation:
m=(-12+14)/(-18+22)=0.5
y+14=0.5(x+22)
y=0.5x-3
Multiply bc it says it's 10 times it's hatchling legnght, and the word times suggests that you need to multiply.
Answer:
Step-by-step explanation:
I think the median you are asking is the middle value,
because there is a total of 20 vehicles, there are two middle number: 31 and 31.
To solve this:
you first plus these two numbers together, you will get 62.
then divide them by 2, then you will get the middle number.
the middle number will be 31. ( actually because theese two number are the same, you do not really need to plus them then divide by 2, you could just answer the question 31, but because when you do other question and has the same situation but not the same number, (suppose you got 20 and 21) Then you need to do this question like I said above)
I wish this could help you.
