What is the slope of this line? Please help someone, anyone.
Sphinxa [80]

For this case we have that by definition, the slope of a line is given by:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

Where:

(x_ {1}, y_ {1})and(x_ {2}, y_ {2})are two points through which the line passes.

According to the figure we have to, the line goes through:

(x_ {1}, y_ {1}) :( 0, -2)\\(x_ {2}, y_ {2}): (- 2,0)

Substituting we have:

m = \frac {0 - (- 2)} {- 2-0} = \frac {0 + 2} {- 2} = \frac {2} {- 2} = - 1

Thus, the slope of the line is -1.

Answer:

m = -1

Margarita [4]

Answer:

880 high-quality version

Step-by-step explanation:

I think the below is your full question:

<em>A Web music store offers two versions of a popular song. The size of the standard version is 2.1megabytes (MB). The size of the high-quality version is 4.5 MB. Yesterday, there were 1290 downloads of the song, for a total download size of 4821 MB. How many downloads of the high-quality version were there?</em>

Here is my answer:

Let x is the number of high-quality version

So the number of standard version= 1290 - x

We also know:  total download size of 4821 MB. which means:

4.5x + 2.1(1290-x) = 4821

<=> 4.5x+2709-2.1x=4821

<=> 2.4x=2112

<=> x=880

So there were 880 high-quality version

The cost of 32.57ft^2 is Rs. 18,239.2 which is the cost of renting one tent.

  • edge length = 3ft
  • area = ?

<h3>Area of a Square Pyramid</h3>

The formula of a square pyramid is given as

A = l^2 + 2l\sqrt{\frac{l^2}{4} + h^2} \\

Let's substitute the values and solve for the area of the square pyramid.

A = l^2 + 2l\sqrt{\frac{l^2}{4} + h^2} \\\\A = 3^2 + 2*3\sqrt{\frac{3^2}{4} + 3.63^2} \\A = 9 + 6{\sqrt{15.43} } \\A = 32.57ft^2

Since the cost of 1 square foot  = Rs. 560

32.57 ft^2 = x

1sq = 560\\32.57 = x\\x = 32.57 * 560\\x = 18,239.2

The cost of 32.57ft^2 is Rs. 18,239.2 which is the cost of renting one tent.
