The answer is C! Annuity means "a fixed sum of money paid to someone each year", which is similar to what the letter C is suggesting.
1 + 1 = 2
2 + 2 = 4
4 + 3 = 7
7 + 4 = 11
11 + 5 = 16
The answer is 16.
The slope that you need to use is 3/2 which is perpendicular to the slope of -2/3.
Use:
y-1=3/2(x+6)
y-1=3x/2 + 9
y=3x/2 + 10
y=3x/2+10 is the final answer
Kalon + Marna = 12/7 hours working together
( I attached two formulas. Use formula 3)
Worker 2 Time = (worker 1 Time) * Total Time / [(worker 1 Time) - Total Time]
Worker 2 Time = ((4) * 12/7) / [4 - 12/7]
Worker 2 Time =
