Answer:
f-1(x) = (x - 16)/40
B
Step-by-step explanation:
Call f(x) = y
Interchange x and y
x = (5y + 2)*8 Remove the brackets
x = 40y + 16 Subtract 16 from both sides
x - 16 = 40y Interchange the left and right sides
40y = x - 16 Divide by 40
y = (x - 16)/40
f-1(x) = (x - 16)/40
Answer:
12
Step-by-step explanation:
23 - (2 + 4) - 15/3
23 - (6) - 5
23 - 6 - 5
12
Answer:
24 Years
Step-by-step explanation:
Rule of 72 is an approximation that you can use to estimate the time it will take for something to double in value at a compound rate of interest
use the following equation
72/(i*100)
we have
72/(.03*100)
72/3=24
