2 positive integers is the answer to this question because if you test the hypothesis, for example lets take 1 and 2 for instance. |1+2| = |1| + |2| 3=3. Whereas if you tried other hypothesis' they would not work. So, 2 positive integers is the answer.

$-\dfrac{1}{2}x+6=-\dfrac{1}{2}\left(\dfrac{-\frac{1}{2}x}{-\frac{1}{2}}+\dfrac{6}{-\frac{1}{2}}\right)=-\dfrac{1}{2}\left(x-\dfrac{6\cdot2}{1}\right)=\boxed{-\dfrac{1}{2}\left(x-12\right)}$

If the bathtub holds a total of 46.2 gallons, how many minutes would it take to fill the entire tub? Write an equation in one va

sergejj [24]

Answer:

It will take 2.8 minutes

Step-by-step explanation:

Given

$x \to Minutes$

$y \to Gallons$

See attachment for complete question

Required

Time to fill the tube with 46.2 gallons

The attached table is a represents a direct proportional relationship between x and y.

This relationship is:

$y = kx$

Where k is the constant of proportionality.

When (x,y) = (1,16.5), we have:

$16.5 = k*1$

$16.5 = k$

$k=16.5$

So, we have:

$y = kx$

$y = 16.5x$

To calculate the required time to fill 46.2 gallons, we make x the subject

$x = \frac{y}{16.5}$

Where

$y =46.2$

$x = \frac{46.2}{16.5}$

$x = 2.8$
