Try plugging in the equations
and d are not it because they eliminate x
4x-12=3x-4
x=8
4x-12=6x-18
2x=6
x=3
so both b and c work as answers
Answer:
can you write these in proper way
The mean and median of this date set is;
Mean: 44.25
Median: 7
Date set in order: 2,4,5,7,7,8,9,18
Return rate, r = 3% = 0.03
x = initial investment
b = final balance
After 1 year, the balance i
b = initial investment + interest
b = x + r*x = (1 + r)*x
Because r = 0.03,
b = 1.03x (after 1 year)
The answer for 3(6-8)^2 + 8÷2 = 16 ☺
