Answer:
<h2>x = 3</h2>
Step-by-step explanation:
Look at the picture.
Therefore we have:
 <em>cross multiply</em>
            <em>cross multiply</em>

 <em>divide both sides by 3</em>
             <em>divide both sides by 3</em>

 
        
             
        
        
        
Answer:
D.18
Step-by-step explanation:
6-x=-12
-x=-12-6
-x=-18   divide both sides by -1
x=18
 
        
             
        
        
        
Answer:
the slope is POSITIVE (answer A)
Step-by-step explanation:
The line goes through: (-1, -2)  and ( 2, 1)
Then the slope can be calculated as:
slope = (y2 - y1) / (x2 - x1)
in our case:
slope = (1 - -2) / (2 - -1) = (1 + 2) / (2 + 1) = 3 / 3 = 1
Therefore, the slope is POSITIVE (answer A)
