A bathtub is filled with 38 1/3 gallons of water. If 2 3/5 gallons splash out, how much water is left in the tube
musickatia [10]

So let's convert these to improper fractions:

38\frac{1}{3}=\frac{115}{3}

2\frac{3}{5}=\frac{13}{5}

Then let's convert these fractions so that they have a denominator of 15 so we can better compare these numbers:

\frac{115}{3}=\frac{575}{15}

\frac{13}{5}=\frac{39}{15}

So when we have \frac{39}{15} gallons splash out, we are left with \frac{536}{15} gallons or 35\frac{11}{15} gallons in the tub.

Please help Fast I need to turn this in before 12:20
zhannawk [14.2K]

if you put the points into the equation y2 - y1/x2 - x1 you'll end up with a zero in the denominator, which indicates a vertical slope. Basically the slope(m) is undefined

It's really easy to tell if your answer is going to be undefined if both the x values are the same (in this case they're both 9)

Find the slope of the graphed line.
gayaneshka [121]

Answer:

3/4 shall be our slope.

Step-by-step explanation:

You can solve the slope by doing this formula y₂ - y₁ / x₂ - x₁ = slope.

Your coordinates:

(-4,0) and (0,3)

You have to set up your formula:

3 is the y2 and 0 is the y1

3-0 for y so far.


Now, set up the x's

0 is our x2 more known as our second x

Then our x1 is -4

0 - (-4).

Our Formula:

3-0 / 0+4

**Notice the negatives canceled to a positive due to the rule.**

3/4 shall be our slope.

You could've also risen and run starting from (-4,0) to (0,3) to get a slope of 3/4.
