Your question is a bit unclear, but I will try to answer it anyway.
The expression 3x + 2(x - 1) - 4 simplified is:
3x + 2(x - 1) - 4
= 3x + 2x - 2 - 4
= 5x - 6
I cannot tell what the answers are but I am guessing they are these?:
A) 3x + 2x - 2 - 4
B) 5x - 6
C) 3(x - 4)
D) 3(x + 2) - 6
E) 6(x - 1)
Answer A is one, and so is answer B. If I read your question accurately.
I hope I helped!
Answer:
C) 99 + 3x
Step-by-step explanation:
Since it's always going to cost 99, it'll stay like that since it's a constant
Since it's 3 PER person, that means 3 will have a variable: 3x
Answer: Choice D) |K| = 57
------------------------------------------------------
Explanation:
The notation |K| means "the number of items in set K". It is similar to the notation n(K). In this case, we simply add up all the values in the circle labeled K. There are four of these values which are 13, 8, 17, 19. Add up these values to get 13+8+17+19 = 57. So there are 57 items in set K.

Hello from MrBillDoesMath!
Answer:
(x-8)^(1/3) +2
Discussion:
To find the inverse of a function swap the values of x and y in the original equation y = (x-2)^3 +8 and solve for y.
y = (x-2)^3 +8 => original function. swap x and y values
x = (y-2)^3 + 8 => subtract 8 from both sides
x - 8 = (y -2)^3 => take cube root of both sides
(x-8)^(1/3) = y - 2 => add 2 to both sides
(x-8)^(1/3) +2 = y => y is the inverse
Thank you,
