Answer:
independent system
Step-by-step explanation:
The first linear equation () can be written in slope y-intercept form by solving for the y variable. When it is in that form, one can easily understand its geometrical shape and distinguish if it the same, if it crosses or if it is parallel, to the second line ()
We proceed to re-write it in slope y-intercept form:
Therefore it has a slope of "-1" and a y-intercept of "-5", while the second line has slope "1" and y-intercept "-7".
Therfore, they are lines that intercept at a unique point, and therefore represent an independent system.
Step One
========
Start with how much was transferred.
r = 4.4 megabytes / second
t = 32 seconds
amount transferred = ????
Formula: amount = r*t
amount = 4.4 * 32 = 140.8 megabytes were transferred.
Step Two
=======
Find the number of megabytes on the drive before the transfer took place.
The amount transferred = 140 megabytes.
The drive recorded when he was done there was 384 megabytes
The amount on the drive was 384 - 140 = 243.2 megabytes to begin with.
Step 3
=====
Find the number of megabytes left before the transfer.
1000 - 243.2 = 756.8 megabytes were left before he began his 32 second transfer.
Step 4
=====
Find the amount of time it would take to fill the drive.
He needs to transfer 756.8
The rate of transfer = 4.4 megabytes / second
t = ????
Formula: Amount transferred = r * t; t= amount / r
t = 756.8 / 4.4
t = 172 seconds.
Interesting question. Thanks for posting. It is a unique application of the more familiar formula
d = v * t

Step-by-step explanation:
Adding positively to an x moves it right, and negative moves left. Adding to a y moves it up, and subtracting moves it down.
Answer:
or
Step-by-step explanation:
Well, the center origin of the circle is given (h,k) = (5,7).
We have to find our radius as they gave us a point. from origin to the edge of the circle.
Using the formula: (x - h)^2 + (y - k)^2 = r^2
Plug in our (h,k) = (5,7) and (x,y) = (10,19) to solve for radius.
(x - h)^2 + (y - k)^2 = r^2
(10 - (5))^2 + (19 - (7)^2 = r^2
(5)^2 + (12)^2 = r^2
25 + 144 = r^2
r^2 = 169
r = 13
