Mabel spends 4 hours editing a 3 minute video. she edits at a constant rate. how long does mabel spend to edit a 9 minute video? 
she spends 4 hours on a 3 minute video 
so there are 60 minutes in an hour 
4 hours with 60 minutes- 4x60=240
so she spent 240 minutes on a 3 minute video 
3 divided by 240 
3/240= 0.0125 
so her constant rate is 0.0125 minutes an hour 
so divide 9 minutes by her constant rate 
9/0.0125 = 720 
so she spends 720 minutes on a 9 minute video. 
divide 720 by 60 since there are 60 minutes in an hour 
720/60 = 12
so she spends 12 hours on a 9minute video

Answer:
- As the slopes of both lines 'm' and 'n' are the same.
Therefore, we conclude that the equation x-2y=4 represents the equation of the line 'n' if lines m and n are parallel to each other.
Step-by-step explanation:
We know that the slope-intercept of line equation is  

Where m is the slope and b is the y-intercept
Given the equation of the line m
y = 1/2x - 4
comparing with the slope-intercept form of the line equation
y  = mx + b
Therefore, 
The slope of line 'm' will be = 1/2
We know that parallel lines have the 'same slopes, thus the slope of the line 'n' must be also the same i.e. 1/2
Checking the equation of the line 'n'

solving for y to writing the equation in the slope-intercept form and determining the slope

Add -x to both sides.


Divide both sides by -2


comparing ith the slope-intercept form of the line equation
Thus, the slope of the line 'n' will be: 1/2
- As the slopes of both lines 'm' and 'n' are the same.
Therefore, we conclude that the equation x-2y=4 represents the equation of the line 'n' if lines m and n are parallel to each other.
 
        
             
        
        
        
Answer:
The equation of line with given points is 2Y - X - 5 = 0
Step-by-step explanation:
Given points are ( - 3 , 1)   and   (9 , 7)
Equation of line is y = mx +c
where m is the slop of line
Now m = 
Or,    m = 
so, slop = 
∴   slop = 
Now the equation of line with points ( -3 , 1) and slop m is :
 Y - y1 = m ( X - x1)
Or, Y - 1 =   (X + 3)
 (X + 3) 
Or, 2Y - X - 5 = 0
Hence The equation of line with given points is 2Y - X - 5 = 0 Answer
