Answer:
v=8
Step-by-step explanation:
Let's solve your equation step-by-step.
16v−9v=56
Step 1: Simplify both sides of the equation.
16v−9v=56
16v+−9v=56
(16v+−9v)=56(Combine Like Terms)
7v=56
7v=56
Step 2: Divide both sides by 7.
7v
7
=
56
7
v=8

Answer:
dy/dx = -5y - y/x
Step-by-step explanation:
In xy + 5x = 30
Differentiating xy implicitly
y + xdy/dx
Assuming u = xy
In xy = In u
Differentiating In u = 1/u = 1/xy
Differentiating 5x = 5 and differentiating a constant (30) = 0
1/xy(y + xdy/dx) + 5 = 0
(y + xdy/dx)/xy = -5
(y + xdy/dx) = -5xy
xdy/dx = -5xy - y
dy/dx = = (-5xy - y)/x
dy/dx = -5y - y/x
The answer is 23.2 I just entered the data into an online standard deviation calculator.
