Answer:
1600
Step-by-step explanation:
1600 is the answer because
321×5 = 1605 so estimation = 1605
I think it’s six because 3n=6-5 3 n=6-5 then subtract 5 5 from 6 6
F(x) and g(x) were inverse functions, then if f(a) = b, then g(b) = a
f(x) = (5x+1) / x g(x) = x / (5x+1)
f(1) = 6, but g(6) = 6/31 ≠ 1
So, f(x) and g(x) are NOT inverse functions.
This might not be correct but....
I’m going to use rounding,
42 x 2 = 84
84 divides by 3 = 28,
Which is near 30......So the number of people in the group is rounding to about 2 people.
