are there any values for x that make the equation undefined? What are they?2. If a gas was in a 7.5 liter flexible container under 4 atmospheres of pressure, how would the volume of the gas change and what would it be if the pressure was increased to 6.......
1. Solve the equation " 5/x-5 = 6/x " by graphing. Find the solution algebraically to verify your graph. Are there any values for x that are not found in the domain? In other words, are there any values for x that make the equation undefined? What are they?

2. If a gas was in a 7.5 liter flexible container under 4 atmospheres of pressure, how would the volume of the gas change and what would it be if the pressure was increased to 6.5 atmospheres, keeping all other variables constant?

-
1) 5x = 6x-30
x = 30

2) P1V1 = P2V2
7.5*4 = 6.5V2
V2 = 4.62 L

-
1 ) LET 1/x=y
so , 5y-6y=5
so ,y= -5
so x = - (1/5)

U see , solving it we find it to be a linear eqn.....so it will have single soln
But if u put x=0 , soln is undefined bcoz infinite-infinite is not equals to 0.

2 ) pv=PV
7.5*4=6.5*V
So V=4.61 lts

Done !!
