Question

You are given a pair of equations, one representing a supply curve and the other representing a demand curve, where p is the unit price for x items.
and 50p+x-1148=0, 86p-x-28=0, Identify which is the supply curve and demand curve and the appropriate domain. Put the domains in interval notation . For type a.infinity . For more than one interval use a U to represent a "union".
Domain of the supply curve
Domain of the demand curve
b. Determine the market equilibrium. Equilibrium: x = p =
c. Determine the revenue function. Revenue function R(x)=
d. Determine the revenue at market equi

Answer 1

didn't we do this?

Answer 2

i solved the same exact thing earlier.

Answer 3

Domain of both curves is from (-infinity; infinity)

Answer 5

Copy and paste this for domain part:
(-infinity, infinity)
if that doesn't work, try:
(-infinity;infinity)
Keep the parenthesis

Answer 6

webworks sucks luis

Answer 7

wait Luis, u go to a CUNY too? Or some other college that uses webworks?

Answer 8

Answer 9

ame then take a screen of that page and post it as an attachment

Answer 10

it is aksing for seperately , deman ..... and supply....

Answer 11

okay ame, i told you, they're both the same, put
(-infinity; infinity) for both of them the only thing that I'm not sure about is if they ask you to use a , instead of ;

Answer 12

they're both either
(-infinity; infinity) or
(-infinity, infinity)

Answer 13

ok

Answer 14

luis, she's talking to me, nevermind

Answer 15

Domain of the supply curve ????????
Domain of the demand curve ?????????

Answer 16

omg:
Domain of the supply curve: (-infinity; infinity)
Domain of the demand curve: (-infinity; infinity)
