Answer:
Step-by-step explanation:
Data provided in the question:
Initial volume of water = 15 liters
Concentration of salt = 4 liters per minute
x be the amount of salt, in grams, in the fish tank after t minutes have elapsed
The unknown concentration of incoming brine c.
Now,
Salt concentration per minute =
For x amount of salt =
Therefore,
Answer:
y=-1/3x-2
Step-by-step explanation:
First off, lets outline that parallel lines have the <u>Same Slope</u>. So we can plug in -1/3 as our slope, or m.
Lets plug in -1/3 as our slope in Point Slope form to find the y intercept. Point slope form should be attached in an image below.
1) Plug slope and points into point slope form:
y+1=-1/3(x+3)
2) Distribute -1/3 to x and 3:
y+1=-1/3x-1
3) Subtract 1 from both sides:
y=-1/3x-2
Now we have our answer is slope intercept form!
