Describe the effect a positive shift in demand would have on the values of Price and Quantity in a supply and demand curve.

Pie

Answer: Equilibrium price and quantity will increase.

Step-by-step explanation:

If there is a positive shift in demand i.e. rightward shift in the demand curve but the supply curve remains constant.

Then As shown in the figure, At the beginning 'E' is the equilibrium point with Equilibrium price "P" and Equilibrium quantity "Q".

But when there is positive shift in demand curve say D' then,

Equilibrium price will increase and equilibrium quantity will also increase.

say it becomes P' and Q'.

So, Positive shift in demand curve increases the price and Quantity in a supply and demand curve.

Simplify the expression: 6 + 8j - 9j + -5j - 3

dangina [55]

So first you’ll combine the J’s.
8j - 9j = 1j
+ -5j
Which will be -4j.
That makes: 6 + -4j - 3
So you can subtract 6-3 to make 3.
Which makes 3 + -4j
That’s the answer!

Answer:

x = 2π3

Step-by-step explanation:

csc(x)csc(x) , x=πx=π

3x+2y+zx+y+z3x+2y+zx+y+z , x=2x=2 , y=3y=3 , z=1z=1

cot(3x)cot(3x) , x=2π3

You would change 30 percent to a decimal, so .3 is your multiplyer
