Let's try the actual solution of the system
<span>y = –2x + 1
y = –2x – 3
Note that the slopes of the graphs of these two lines are the same: -2.
That means that the lines are parallel to one another.
Only the y-intercepts (1 and -3) are different.
Since the 2 lines never intersect, the system has no solution.

Answer:20
Step-by-step explanation:
Answer:
Step-by-step explanation:
We want to find a common factor for
and
We factor each of them to get;
and
We can observe now that;
The factor common to both expression is
Charles can do the whole job in an hour, Bill can do 1/2 of the job in an hour, and Bob does 1/3 of the job in an hour. Therefore, they do a total of 1+1/2+1/3=11/6 of the job in an hour, meaning it takes them 6/11 of an hour. This is 6/11*60=360/11 minutes, or approximately 33 minutes.
Answer:
8.8 inches
Step-by-step explanation:
Since the level is proportional to the time, when the time increases from 5 to 11 (by a factor of 11/5), we expect the water level to increase by a factor of 11/5 to ...
(4 in) · 11/5 = 44/5 in = 8 4/5 in
