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: option 6. from the list
Answer:
x=5
y=4
Step-by-step explanation:
The sides with the 2 bars are equal so
7x-4 = 31
Add 4 to each side
7x-4+4 = 31+4
7x = 35
Divide each side by 7
7x/7 = 35/7
x =5
The sides with 3 bars are equal
4y+8 = 24
Subtract 8 from each side
4y+8-8 = 24-8
4y = 16
Divide by 4
4y/4 = 16/4
y =4
Answer:
3/8 or 0.375mph.
Step-by-step explanation:
All you have to do for this is divide one fourth by two thirds. This way, you get the units to work out as well.

Ans:C.
Remember equation Y=MX, and M is Slope.
now we know the line through the given point <span>(8,3)
</span>so put (8,5) into the equation
then equation Y=MX → (Y-3)=M(X-8)
and Slope M=5
so (Y-3)=5(X-8)
