Answer:
f(x + 3) = (4x + 13)/(x - 3)
Step-by-step explanation:
If f(x) = (4x + 1)/(x - 6)
then in f(x + 3)...js replace x with (x + 3)...
f(x + 3) = (4(x + 3) + 1)/(x + 3 - 6)
;f(x + 3) = (4x + 13)/(x - 3)
Let's assume two variables x and y which represent the local and international calls respectively.
x + y = 852 = total number of minutes which were consumed by the company (equation 1)
0.06*x+ 0.15 y =69.84 = total price which was charged for the phone calls (Equation 2)
from equation 1:-
x=852 -y (sub in equation 2)
0.06 (852 - y) + 0.15 y =69.84
51.12 -0.06 y +0.15 y =69.84 (subtracting both sides by 51.12)
0.09 y =18.74
y= 208 minutes = international minutes (sub in 1)
208+x=852 (By subtracting both sides by 208)
x = 852-208 = 644 minutes = local minutes
