We have that
x² − 8xy + y²<span> = 8
</span>2x-8y-8x(dy/dx)+2y*(<span>dy/dx)=0
</span>8x(dy/dx)-2y*(dy/dx)=2x-8y
[8x-2y]*(dy/dx)=2x-8y
(dy/dx)=[2x-8y]/[8x-2y]
(dy/dx)=2*[x-4y]/2*[4x-y]
(dy/dx)=[x-4y]/[4x-y]
the answer is
(dy/dx)=[x-4y]/[4x-y]
Answer: 24miles/hour
Step-by-step explanation: Speed is the change in distance of a body with respect to time.
Speed = Distance/tIme
Given parameters
Distance = 8miles
TIME = 20minutes
Convert minutes to hour
since 60minutes = 1hr
20 min = x
cross multiply
20 = 60x
x = 20/60
x = 1/3
Hence 20mins = 1/3 hr
Speed = 8miles/(1/3)hr
speed = 8 miles * 3/1 hr
speed = 24 miles/hr
