(2m + 7) - (3 - 4m) 
First distribute the (-) in front of the quantity of 3 - 4m. 
Think of it as this: 
-1(3 - 4m) 
You multiply each number inside the parenthesis by -1. 
So: 
3*-1 = -3
-4m * -1 = 4m
Now that you've distributed the negative you can remove the parenthesis. 
Now you'll just set it all up like you would any normal problem. Because -3 is negative you'll make it subtract.... I'll show you what I mean: 
2m + 7 - 3 +  4m 
Combine like terms (Terms which have the same variables... in this case the same number of m's)
Rearranging them can help!
4m + 2m + 7 - 3 
6m + 7 - 3
6m + 4, is our difference!
        
                    
             
        
        
        
Answer:
See attachment for graph
Or
The slope intercept form is 
Step-by-step explanation:
Assuming you want to graph the straight line given in point-slope form as 

Then we need at least two points on this line
When we compare to the point-slope formula  then we  obtain (-5,-2) as a point on this line so we plot it.
 then we  obtain (-5,-2) as a point on this line so we plot it.
When x=0, y=4(0+5)-2=18 so we plot (0,18)
We then draw a straight line through as shown in the attachment.
On the other hand, if you had wanted the equation slope intercept form, then we expand to obtain:



 
        
             
        
        
        
Answer:
She will have saved $195
Step-by-step explanation:
If we had her two paychecks together she will have saved $650.
30% of 650 = 195
We get this by taking 650 times .3 
 
        
             
        
        
        
Answer:
c 
Step-by-step explanation:
i just took the test
 
        
             
        
        
        
50 + .4x = 70 + .3x
.4x = .3x + 20
.1x = 20
x = 200
Let x be the number of miles.
They have to drive 200 miles.
