Answer:
6.38548 years
Step-by-step explanation:
1 = 2
1/2 =
ln(1/2) = 42k ln(e)
ln(1/2)/42 = k
k = -0.01650
~~~~~~~~~~~~~~
45 = 50
45/50 =
ln(45/50) = -0.01650 t ln(e)
ln(45/50)/ -0.01650 = t
t = 6.38548 years
Answer: x = 2/3 and y = 2/3
Step-by-step explanation:
I've attached the solution.
From the solution, you get y = -5x + 4 and
y = x.
Now,
Put y = x in y = -5x + 4.
x = -5x + 4
6x = 4
x = 4/6
x = 2/3
So, y = 2/3 because y = x.
