Container A has 200 L of water, and is being filled at a rate of 6 liters per minute. Container B has 500 L of water, and is bei

zheka24 [161]

Answer:

25 minutes

Step-by-step explanation:

Let the amount of time, in minutes, be x.

For Container A, we can write:

200 + 6x [since it has 200 and is being filled with 6 per minute]

For Container B, we can write:

500 - 6x [since it has 500 and is being drained with 6 per minute]

To find, we equate them and solve for x:

$200+6x=500-6x\\6x+6x=500-200\\12x=300\\x=\frac{300}{12}\\x=25$

<em>So, in 25 minutes (m), the two containers will have same amount of water</em>

Must m in the equation y=mx+b always be a positive number?

Effectus [21]

If the slope of the number is positive (the graph goes upward from left to right), then m will be positive, but if the slope is negative (the graph goes downward from left to right), then m is negative. So, no. M does not have to be a positive number, it may also be negative.
