What is the slope of the line that passes through the points (-9,0) and (-17 , 0 ) ​

Mathematics
1 answer:
marishachu [46]2 years ago
4 0

Answer:

\mathrm{Slope=== > 0}

Step-by-step explanation:

Hi student, let me help you out!

<u>.............................................................................................................</u>

<u></u>

First, let's recall the slope formula: \boxed{\mathrm{\cfrac{y2-y1}{x2-x1}}}}, where y2 and y1 are y-coordinates; x2 and x1 are x-coordinates.

Plugin the values: \mathrm{\cfrac{0-0}{-17-(-9)}}.

Upon simplifying, we obtain \mathrm{\cfrac{0}{-17+9}}.

Upon simplifying this further, we obtain \mathrm{\cfrac{0}{-9}}.

0 divided by anything results in 0.

✨ ∴, the slope of this particular line is 0, and this line looks something like this: \rule{200}{1}.

See, it's a horizontal line, with a rise of 0, meaning that it goes up 0 units.

Hope this helped you out! Ask in comments if even the slightest queries arise.

Best Wishes!

\underline{\rule{300}{5}}

Round your answer to the nearest tenth if necessary. Use 3.14 for .
harina [27]

Answer:

\boxed{\rm \: Volume_{(Drum)} = 5024 \: in {}^{3} }

Step-by-step explanation:

Given :

  • Diameter of a drum = 20 inches
  • Deep ( height ) of the drum = 16 inches
  • π = 3.14

To Find:

The volume of the drum.

Solution:

We all know that drum is cylindrical.So we'll use the formulae of the volume of cylinder,to find its volume.

\boxed{\rm \: Volume_{(Cylinder)} = \pi{r} {}^{2} h}

Where,

  • r = radius
  • h = height (deep)
  • π = 3.14

The value of radius ain't given,but the diameter is given.We can use the formulae of radius.

\rm \: Radius = D/2

  • D = diameter

Substitute the value of diameter:

\rm \: Radius =  \cfrac{20}{2}  = 10

Hence,the radius is 10.

So we could now use the formulae of the volume of cylinder:

\rm \: Volume_{(Cylinder)} = \pi{r} {}^{2} h

  • π = 3.14
  • r =10 in
  • h = 16 in

<em>[Firstly bring the answer in terms of π then plug π = 3.14 and then simplify.]</em>

\rm \: Volume_{(Drum)} = \pi(10) {}^{2} (16)

\rm \: Volume_{(Drum)} =\pi100(16)

\rm \: Volume_{(Drum)} = 1600\pi

\rm \: Volume_{(Drum)} = 1600 \times 3.14

\boxed{\rm \: Volume_{(Cylinder)} = 5024 \: in {}^{3}}

<u>Hence, we can conclude that:</u>

The volume of this drum is 5024 in^3.

Simplify the given polynomial and use it to complete the statement (8x^2 - 5x -7) - (9x^2 - 3x -5) + (x+7)(x + 1)
Lunna [17]

Answer:

The answer to your question is:    6x + 5

Step-by-step explanation:

                          (8x² - 5x -7) - (9x² - 3x -5) + (x+7)(x + 1)

                          8x² - 5x - 7 - 9x² + 3x + 5 + x² + 8x + 7

                          9x² - 9x² - 5x + 11x + 12 - 7

                         6x + 5

3.<br> Find the value of x.<br> 16<br> 10<br> 14<br> 9
Airida [17]

Answer:

x = 9

Step-by-step explanation:

Both the triangles are similar, so the corresponding sides are also similar.

That is,

12 / 8 = x / 6

Cross multiply,

x * 8 = 12 * 6

8x = 72

Divide 8 on both sides,

x = 72 / 8

x = 9
