Answer:
Step-by-step explanation:
We have
So we find GCD = 1
2) By back substitution we get
71407 (543) - 19387(2000) =1
So x = 543 and y = -19387
Because we got 71407 (543) - 19387(2000) =1
y cannot be positive
y can only be negative
Answer:
2327.49 ---> 25 hrs
starting plot points (0,640) and ending (25, 2327.49)
Step-by-step explanation:
b = 640
r = 5.3% = 0.053
t = 25
y = 640 ( 1 + 0.053)^25
y = 640 ( 1.053)^25
y = 2327.49 ---> 25 hrs
starting plot points (0,640) and ending (25, 2327.49)
