Point-slope form is:
y - y1 = m(x - x1)

y1 = y-value you're given. x1 = x-value you're given. m = slope.

Now just put the numbers into the equation.
y + 3 = - 4(x + 6)

Helen [10]

Answer:

In 3 seconds the cup is filled with 105\ cm^3<u>.</u>

Step-by-step explanation:

Given:

2 seconds = 70\ cm^3 water

We need to find the percent of the cup that is filled with water after 3 seconds.

Solution:

Now Given:

The cup was filled at a constant rate.

First we will find the volume of water filled in the cup after 1 seconds.

2 seconds = 70\ cm^3 water

1 seconds = Volume of water filled in 1 second.

By Using Unitary method we get;

Volume of water filled in 1 second = \frac{70}{2}= 35\ cm^3

Now we will find the volume of water filled in the cup after 3 seconds.

1 second = 35\ cm^3 of water is filled

3 seconds = volume of water filled in the cup after 3 seconds

Again by using Unitary method we get;

volume of water filled in the cup after 3 seconds = 35 \times 3 = 105\ cm^3

Hence In 3 seconds the cup is filled with 105\ cm^3.

To find the percent of the cup filled with water after 3 seconds we would required the dimensions of the cup which is not available in the question.

Answer:

Step-by-step explanation:

Since they already have a common denominator of x+1 we can add the numerators

(2x+4-x+5)/(x+1)

(x+9)/(x+1)

What is the slope of the line that passes through these two points? (-3, 2) (4, 2)
Alik [6]

Answer: 0

Step-by-step explanation:

To find slope, I found that an easy way is the equation y2 - y1 over (divided by) x2 - x1

so for this, it would be:

\frac{2 - 2}{4-(-3)}

which is 0/7

0 divided by 7 is 0, so there is your answer
