72, because 360/4 courses = 90 as an average for Adrianna. This means that 360/5 courses equals 72 for roberto.
Answer:
The point slope form is 
The slope(m) can be calculated using 
:
Using Point One, the point-slope form is determined as:
The y-intercept(b) can be calculated as:
You're almost looking at the solution. Almost.
If it only said " r = 1 ", then that would be the solution right there.
But it says " | r | = 1 ", so there's a little more to it.
'r' can be either +1 or -1 and that equation will be a true statement.
So +1 and -1 are both solutions.
Answer:
You could talk on the phone for 200 minutes at night, or 40 minutes during the day.
For every 5 minutes you reduced your night time talking, you could talk during the day for 1 minute.
Step-by-step explanation:
0.50d + 0.10n < $20
0.50d < $20 --> d < 40 minutes
0.10n < $20 --> n < 200 minutes
Answer:
We have the equation of the line as : 4x+2y=12
Step-by-step explanation:
Now 4x+2y=12
=> 2y = 12 - 4x
=> y = 6 - 2x
A line with a slope m and y-intercept c can be written as y = mx + c
In the case of y = -2x -...
