Answer: B 
a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. 
Hope this helps!
        
             
        
        
        
We are asked in the problem to determine the inverse of the relation y = 3x + 12. first step is to express the equation in terms of y, that is y -12 = 3x, then exchange the places of x and y, that is x - 12 = 3y. This is the final answer
        
                    
             
        
        
        
You just have to add or subtract the percent of a number from the original 
A) 5percent of 40=2 ( 0.05*40) 
Since it’s increase add 2 to 40=42
F) 40percent of 25= 10 (0.4* 25)
25-10=15 
        
             
        
        
        
Answer:
Okay, here's the method I'm going to use.
If you drive north 6 miles, and then drive east 19 miles, you are technically making a triangle.

You are just missing the last side of the triangle: the straight line stretching from across your starting point to the ending point. You can find this by using the Pythagorean theorem.
a^2 + b^2 = c^2
6^2 + 19^2 = c^2
36 + 361 = c
397 = c
 = 19.924859
 = 19.924859
Rounded to the nearest tenth, your answer is
19.9 miles
