Find the equilibrium point for the pair of supply and demand functions. Demand: q=18/x Supply: q=x/2
storchak [24]

Answer:

The equilibrium point is at x = 6

Step-by-step explanation:

Given

Demand (q) = \frac{18}{x}

Supply (q) = \frac{x}{2}

Required

Determine the equilibrium point

The equilibrium point is determined by

Demand = Supply

Substitute values for Demand and Supply

\frac{18}{x} = \frac{x}{2}

Cross Multiply

x * x =  18 * 2

x^2 = 36

Take positive square root of both sides

x = 6

Hence;

<em>The equilibrium point is at x = 6</em>

The question on the top old explain
Elis [28]
So it's asking you to create an expression on how much you spent.
So you have already spent $30 on a DVD and $20 for a CD. And we don't know how much the videos are so that is x.
Your equation is going to be something like 30+20+5x but since it says it wants it in simplest form it's going to be 50+5x or 5x+50 either way that will be your equation answer. The reason it's that equation is because we know how much you spent already which is 50 and since you bought 5 videos of an unknown number that's how you get 5x.
50+5x
