The equilibrium referred to here is the dynamic equilibrium. It means that there is a change happening, but the opposite change are equal so they cancel out. So, we can determine the equilibrium price at the point where the demand and supply curve intersect. That would be at the quantity of 60 units. Therefore, the equilibrium price is $10.
Answer:
Yes
Step-by-step explanation:
If , then .
If are positive, then .
So if I multiply both sides of by it will not effect the direction of the inequality since it is of positive value.
This actions gives us .
Using foil we can multiply the left hand side out resulting in:
Add on both sides:
.

Also consider the function . This function increases after is 0. This means as you increase the value for the value for increases for positive value inputs of .
X^2-4x+4
(x-2)(x-2) or (x-2)^2
Check:
-2-2=-4
-2*-2=4
The product of two rational numbers is always rational.
His score changed by -20.
Because 4*-5 equals -20.
