Answer:
4
Step-by-step explanation:
2x+y=12
y=-2x+12
y-2=3(x-2)
If it’s parallel to each other: the slope has to be the same. 
If is perpendicular to each other: the slope should be the reciprocal to each other. 
The first equation has a slope of -2
The second has a slope of 3
Neither the condition meet. So the answer is 4
 
        
             
        
        
        
Answer:
q<392
Step-by-step explanation:
First, we turn words into an inequality. Then, we solve for q.

It is also a good idea to check our answer, to make sure it is reasonable and we did not make a careless mistake.

The value satisfies the equation, so this should be correct.
