Answer:
A
Step-by-step explanation:
A is equal to 5d-5
I just went through all eh choices
It can’t be b or c becuase when distributed, it automatically is -5d+25 or vice versa with a different sign so their out
D is impossible becuase you can’t jsut flip a subtraction problem
And A is possible because adding a negative basically means subtracting so if flipped The signs have to change
Answer:
Step-by-step explanation:
11 is A ( i think)

Choosing 4 men from seven can be done in 7C4 = 35 ways
(There are 7 to choose from then 6 and 5 and 4 = 7 x 6 x 5 x 4
but we don’t want them in order so we need to divide by 4! = 4 x 3 x 2 x 1)
Similarly choosing 4 women from 11 can be done in 11C4 = 330 ways.
Total number of ways to choose 4 men and 4 women = 35 x 330 = 11550
Answer:
B. f(x) = -x + 11
Step-by-step explanation:
First if you rearrange the equation you get f(x) = -x + 11, like this:
x + y = 11
Minus x from both sides
y = -x + 11
F(x) and y are interchangeable so we just put f(x) in
f(x) = -x + 11
Each of the graphs are attached and we see that they are the same!
