Step-by-step explanation:

dy/dx=4x-y means 4x-y=0

dy/dx=x-2y also means x-2y=0 then

4x-y=x-2y

3x=-y

y=-3x

x=-y/3

The sum of 5 consecutive numbers is 200. What is the smallest number?​
Vikentia [17]

Answer:

Hey!

Your answer is 44!

Step-by-step explanation:

Here's how...

x+(x+2)+(x+4)+(x+6)+(x+8)=200

5x+20=200  (minus 20 on both sides to get 5x by itself)

5x=180  (divide both sides by 5 to get just x)

x=36

5th number - x+8=36+8=44 (simple substitution and addition)
