Step-by-step explanation:

Given problem;

Write the equation of the line with the given slope and y-intercept

The equation of a line is expressed as;

y = mx + b;

m is the slope and b is the y-intercept

7. m = -5, b = -6

y = mx + b

Input the parameters:

y = -5x -6

8. m = 1, b = -4

y = mx + b

Input the parameters:

y = x - 4

9. m = 0.4, b = -9

y = mx + b

Input the parameters:

y = 0.4x - 9

10. m = 0, b = 3

y = mx + b

Input the parameters:

y = 3

Problem PageQuestion A Web music store offers two versions of a popular song. The size of the standard version is 2.6 megabytes

dalvyx [7]

Answer:

There were 210 downloads of the standard version.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of downloads of the standard version.

y is the number of downloads of the high-quality version.

The size of the standard version is 2.6 megabytes (MB). The size of the high-quality version is 4.2 MB. The total size downloaded for the two versions was 4074 MB.

This means that:

$2.6x + 4.2y = 4074$

Yesterday, the high-quality version was downloaded four times as often as the standard version.

This means that $y = 4x$

How many downloads of the standard version were there?

This is x.

$2.6x + 4.2y = 4074$

Since $y = 4x$

$2.6x + 4.2*4x = 4074$

$19.4x = 4074$

$x = \frac{4074}{19.4}$

$x = 210$

There were 210 downloads of the standard version.

Which equasion represents a line that is parallel to the line y=-4x+5

Debora [2.8K]

In order to be parallel to your line, a line has to have the same slope as your line. So it has to have slope −4
