4
Step-by-step explanation:
Answer:
Center = (7, - 5)
Radius = 3
Step-by-step explanation:

The system of the equation doesn't give the solution at (-3, -6).
<h2>Given to us</h2>
<h3>Equation 1,</h3>
-4x+y = 6
solve for y

<h3>Equation 2,</h3>
5x-y =21
substitute the value of y in equation 2,

Substitute the value of x in equation 2,

We can see that the solution of the two equations is at (27, 114). Also, it can be verified by plotting the line on the graph.
Hence, the system of the equation doesn't give the solution at (-3, -6).

<span>If A file that is 256 megabytes is being downloaded and the download is 18.6% complete, then you just need to multiply the 256 megabytes with 18.6%
The calculation would be: 256 megabytes x 0,186= 47.616 megabytes.
If you round up the answer to nearest tenth it will be 47.6 megabytes</span>
