Answer:

The answer to your question is the letter B

Step-by-step explanation:

To calculate the distance between -4 and 1 we need to consider the signs of these numbers.

-4 is negative and 1 is positive.

To know the distance we must subtract 1 to -4

                     Distance = | -4 - 1 |       Use absolute value

                                     = | -5|

                                     = 5

Conclusion

The correct choice is the second one.

|-4 + 1| = |-3| = 3

|-4 - 1| = |-5| = 5

The distance is 5, so the second equation should represent the problem.

A function is valid if each x input has a different y counterpart

In picture D both 3 and 5 repeat --> (3,2)(2,6) and (5,6)(5,8)

This would create an undefined line that would fail the vertical line test (multiple x values on one y value)

Tap A fills a tank in 4hours while B fills the same tank in 3hours. Tap C empties this tank when full in 2hours. If the tank is
boyakko [2]

Answer:

<em>It will take 12 hours to fill the tank</em>

Step-by-step explanation:

Proportions

Tap A fills a tank in 4 hours. It means each hour it fills 1/4 of the tank.

Tap B fills the tank in 3 hours. Each hour it fills 1/3 of the tank.

Tap C empties the tank when full in 2 hours. Each hour it empties 1/2 of the tank.

Each hour, the tank gets filled by:

\displaystyle \frac{1}{4}+\frac{1}{3}-\frac{1}{2}=\displaystyle \frac{3}{12}+\frac{4}{12}-\frac{6}{12}=\frac{3+4-6}{12}=\frac{1}{12}

Since the tank fills 1/12 of its capacity in one hour, it follows that it will take 12 hours to fill the tank
