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:
19
Step-by-step explanation:
5 people in total, divide equally from 95
<span>Simplifying
15.36x[-0.45] = 0
Reorder the terms for easier multiplication:
15.36 * -0.45x = 0
Multiply 15.36 * -0.45
-6.912x = 0
Solving
-6.912x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '-6.912'.
x = 0
Simplifying
x = 0</span>
Answer:
I'm pretty sure it's -4
Step-by-step explanation:
If you substitute in -2, you get e(-2)= -(-2)+ -6
which is equal to 2-6
2-6=-4
