Perpendicular = opposite sign and reciprocal slope
Make equation y= mx + b
3x + 4y = 24
4y = -3x + 24
y = -3/4x + 6
Now make slope perpendicular
Slope = 4/3
The answer would be B.
Present value, P = 20
compounding interest per 6 months, i = 0.025/2 = 0.0125
Number of periods, n = 30*2 = 60 (half-years)
Future value in 30 years
=P(1+i)^n
=20(1.0125)^60
= $42.14
< because it used absolute value to make the |2|=2, which keeps it the same cause it’s already positive
