**Economics**

Graph the supply and demand curves of Qd=500 - 2P and Qs = -100 + 3P

**Math**

Find the derivative of the quotients: y=4X/(X-3) --What would (x-3) be?

**Econ/Math Derivatives**

Find the derivative of the quotients: y=4X/(X-3)

**Science**

The question is: Scientists do their experimental tests more than once, so they can reduce the effects of chance errors. This is called conducting____________? 14 letters. Anyone know the answer?

**Math/Econ**

If the demand curve is P=12.4-4Qd and the supply curve is P=-2.6+2Qs, What is the equilibrium price? What is the equilibrium quantity?

**Math/Econ**

P=12.4-4Qd How do you get P into this equation to make it Qd=12.4-4P?

**Managerial Econ**

How do you get P=12.4-4Qd to equal P=-2.6+2Qs? You have to find the equalibrium so you have to set Qd=Qs so I can't figure out how to get p in the equations and the equations to equal Qd & Qs.
