Ln(xy) - 2x =0
slope of the tangent line = derivative of the function
[ln(xy)]' = [2x]'
[1/(xy)] [y + xy'] = 2
y + xy' = 2(xy)
xy' = 2xy - y =y(2x-1)
y' = y(2x-1)/x
Now use x = -1 to find y and after to find y'
ln(xy) = 2x
x=-1
ln(-y) =-2
-y = e^-2
y = - e^-2
y' = [-e^-2][2(-1)-1]/(-1) = [e^-2](-2-1)= [e^-2](-3) = - 3e^-2

Answer:
Earnings = $1960
Step-by-step explanation:
The question is incomplete; however the missing part of the question asks his total earnings if he worked for 48 hours in a week
First, we need to determine the extra hour worked
Regular Hour = 40
Extra Hour = 48 - 40
Extra Hour = 8
Total Earnings is then calculated as follows:
Earnings = Regular Hours * Regular Charges + Extra Hours * Extra Charges
Earnings = 40 * 35 + 8 * Extra Charges
Since extra charges is twice regular charges, we have:
Earnings = 40 * 35 + 8 * 35 * 2
Earnings = 1400 + 560
Earnings = $1960
