Answer:
x=-2.25,y=-2.25
Step-by-step explanation:
The given system is

We want to solve the system for x and y that makes the system true.
Let us multiply the first equation by 3 while maintaining the second equation:

Subtract the current second equation from the first one.

Divide through by 12:

From the second equation we have:

This implies that:

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.

Answer:
B is the answer
Step-by-step explanation:
I worked it out
Answer:
Area of Square= 12*12= 144
Area of Circle= πr2
Radius= 12/2= 6
Area of Circle= 3.14*6*6 =113.04
Area of shaded region= 144- 113.04 = 30.96 = 31.0 (1 dp)
