Answer:
6 hours.
Step-by-step explanation:
Let t represent time taken by plant 1 in hours to release the waste.
Part of waste released by plant 1 in one hour would be 
.
We have been given that two chemical plant 1 releases waste twice as fast as plant 2, so time taken by plant 2 to release the waste would be 
.
Part of waste released by plant 2 in one hour would be 
.
We are also told that together they fill the tank in 4 hours. So part of tank filled by both plants working together in one hour would be 
.
Therefore, it will take 6 hours for the faster plant to fill the tank working alone.

4. 0
Step-by-step explanation:
You would put the number of bottles sold on the "x" axis and the cost on the "y" axis. If you graph properly it will show a linear relationship, which means you'll have a line like this ➝ / that corresponds with the data.
16x+3y=251 and 8x+4y=148 then you set them up to each other and cancel one coefficient through elimination or find out what X or Y equals and substitute into either equation
Answer:
Step-by-step explanation:
I didn’t see any choices but an inverse function switches the x and y values.
For every (x,y) of f(x) the inverse function will have (y,x) of f^-1(x)
