Explain how to find the slope of the line.

Mathematics
1 answer:
Marina CMI [18]3 years ago
3 0

Step-by-step explanation:

slope =  \frac{y2 - y1}{x2 - x1} \\   =  \frac{1 - 3}{6 - 2}  \\  =   \frac{ - 2}{4}  \\  =  -  \frac{1}{2}

Even if x₁ = 6, y₁ = 1 and x₂ = 2, y₂ = 3 the result remains same.

The perimeter of a rectangle is about 13.9 cm. If you double the width of the rectangle the perimeter is about 17.8 cm. Find the
fredd [130]

Answer:

5cm by 1.95cm

Step-by-step explanation:

Let the length of the rectangle be x

Let the width be y

Perimeter of a rectangle = 2x + 2y

If the initial perimeter of a rectangle is about 13.9 cm, then;

13.9 = 2x + 2y ..... 1

If when the width is double the perimeter is 17.8cm, then;

17.8 = 2x + 4y ..... 2

Subtract 1 from 2;

13.9 - 17.8 = 2y - 4y

- 3.9 = -2y

y = 3.9/2

y = 1.95 cm

Substitute y = 1.95 into 1 to get x;

From 1;

13.9 = 2x + 2y

13.9 = 2x + 2(1.95)

13.9 = 2x + 3.9

2x = 13.9-3.9

2x = 10

x = 5 cm

Hence the dimension of the smaller triangle is 5cm by 1.95cm

I don’t understand, help me out
Vikki [24]

Answer:

a. 76 b. 52

Step-by-step explanation:

The perimeter of a rectangle is the sum of its four sides.

Now all rectangles have a width and a length.

To find the perimeter it is 2 width + 2 length or 2W +2L.

So if the Perimeter P = 344 and Width W = 76 and P = 2W + 2L

Then...

2(76) + 2L = 344 multiply 2 and 76

2L + 152 = 344 subtract 152 from both sides

2L = 192 divide both sides by 2

L = 96

The length is 96.

The equation of an area of a rectangle is A or  area = width x length or W x L

So the equation is A = W x L

If the area is 4732 and the length is 91 then

91W = 4732 divide both sides by 91

W = 52

The width is 52.

Hope that helps, good luck with your homework!

The formula for density is d = m/v,
Mekhanik [1.2K]

Answer:

Kg per cm

or

Kilograms per cubic meter

Step-by-step explanation:

This formula can be represented as something similar to miles per hour (or kilometers per hour). Looking at the fraction will eventually give you the distance for every hour once it its fully simplified.

Use this problem as an example. d=4/2 where 4 means kilograms and 2 means cubic meters. Once fully simplified to 2/1 you can say there is 2 kilograms per cubic meter which is considered your volume.

Ik theanswer is 2,1 how do i sole it tho
kirza4 [7]

Answer:

Step-by-step explanation:

y = 3x - 5

6x + 3y = 15

Substitute the first equation into the second

6x + 3(3x - 5) = 15

6x + 9x - 15 = 15

15x = 30

x = 2

Then use the answer in the first equation and solve

y = 3(2) - 5

y = 6 - 5

y = 1
