Step-by-step explanation:
19
-8+8=0 you left with 19
For implicit, you take the derivative of entire equation. When it is a function of 'y', you must multiply derivative by ' dy/dx'.
For this example, f(x) = x^4, g(y) = cot(y)
After differentiating, solve for 'dy/dx':
Group and factor
group y's with y's and z's with z's
(y²-10y)+(10z-yz)
factor
y(y-10)+z(10-y)
force undistribute -1
-y(10-y)+z(10-y)
factor
(10-y)(-y+z)
(z-y)(10-y) or
(y-z)(y-10)
Unit rate is total price divided by total quantity:
Unit rate = 6.60 / 12
Unit rate = 0.55 each
