Answer:

x = 2

Step-by-step explanation:

A line with undefined slope is a vertical line parallel to the y- axis.

The equation of a vertical line is

x = c

Where c is the value of the x- coordinates the line passes through.

The line passes through (2, - 1), thus the equation is

x = 2

Agent Bourne transferred classified files from the CIA mainframe into his flash drive. The drive had 3 6 . 5 36.536, point, 5 me

I'm not sure what the question is.

Given:
Flash drive capacity 1,000 megabytes
Initial content before transfer of files 36.5 megabytes

After 125 seconds, there were 549 megabytes on the drive.

549 - 36.5 = 512.5 megabytes is the weight of the transferred files.

512.50 megabytes / 125 seconds = 4.1 megabytes per second

The rate of transfer is 4.10 megabytes per second.

1000 - 549 = 451 megabytes free space.

451 megabytes / 4.1 megabytes per second = 110 seconds

It would take an additional 110 seconds to completely fill up the flash drive.

Which two lines are parallel?

Masteriza [31]

Answer:

3x + y = -2
2y = -6x – 8

Step-by-step explanation:

When the equations are written in the same form, the ratio of x coefficient to y coefficient is the same for parallel lines.

These equations in the same form are ...

3x +y = -2
-6x +2y = 4
6x +2y = -8

The first and last of these equations have a ratio of x-coefficient to y-coefficient of ...

(x-coefficient)/(y-coefficient) = 3/1 = 6/2

so the lines are parallel.

The second equation has a ratio that is the opposite of this.

<em>Alternate approach</em>

You can put each equation into slope-intercept form (solve for y). The x-coefficient is then the slope of the line. Parallel lines** have equal slopes.
