(xy)' + (2x)' + (3x^2)' = (4)'
y + xy' + 2 + 6x = 0
xy' = -y -2 -6x
y' = [-y -2 -6x] / x
Now solve y from the original equation and substitue
xy + 2x + 3x^2 = 4 => y = [-2x - 3x^2 + 4] / x
y' = [(-2x - 3x^2 +4) / x - 2 - 6x ] / x
y' = [-2x - 3x^2 + 4 -2x -6x^2 ] x^2 = [ -4x - 9x^2 + 4] / x^2 =
= [-9x^2 - 4x + 4] / x^2
Add the prices together
Then divide by 3.
*6.25 + 3.25 = 9.50/3 = 2 of them pay 3.16 while the other pays 3.17.
Answer:
the answer should be C!
Step-by-step explanation:
When you multiply the y value 0.04 and 5 it comes out as 0.02.
Answer:
-3a+8
Step-by-step explanation:
f(a)=-2a +5
s(a)= a-2-2a=-a+2
We are asked to determine
f(a) +g(a)
= (-2a +5)+ (-a+2)
=-2a+5-a+2
=-2a-a+5+2
=-3a+8
Exact form = 83 over 8
Decimal form = 10.375
Mixed number = 10 and 3 over 8
