Answer: -5
Step-by-step explanation: -3 , -4 , -5 is the third
<span>y-2x=-6 and 5x-y=9
step 1: isolate y in the first equation
y = 2x - 6
step 2: substitute the y value on the 2th equation:
5x-(2x-6)=9
step 3: solve the present equation:
5x - 2x + 6 = 9
3x = 9-6
3x = 3
x = 1
step 4: get the y value by replacing the value of x in </span>y = 2x - 6:
<span>
y = 2*1 - 6
y = 2 - 6
y = -4
S={1, -4}

If you would like to know how many minutes will it take you to mow a lawn that measures 6000 square feet, you can calculate this using the following steps:
800 square feet ... 15 minutes
6000 square feet ... M minutes = ?
800 * M = 15 * 6000
M = 15 * 6000 / 800
M = 112.5 minutes
This will take 112.5 minutes.
Using the slope concept, it is found that the rate of download of the file is of 1920 MB/s.
<h3>What is the slope?</h3>
The slope of a linear function is given by the <u>change in the output divided by the change in the input</u>.
In this problem:
- 3 minutes since resuming the download 6720 total MegaBytes (MB).
- 5 minutes since resuming the download 10560 total MegaBytes (MB) of the file had been downloaded..
- Hence, in 2 minutes, there was a change of 10560 - 6720 = 3840 MB, which means that the slope is:

The rate of download of the file is of 1920 MB/s.
