Answer:
81 in^2
Step-by-step explanation:
Well the formula to find an area of a triangle is (bh) / 2
In this case the base is 18 and the height is 9 
18*9=162
162/2=81
 
        
                    
             
        
        
        
Multiply the first equation by -1
-3x-y=-4
2x+y=5
Add them up 
-x=1
So x=-1
And y=7 
So the first option is correct 
 
        
             
        
        
        
In a day there are 24 hours (obviously)...
so then you put 14/24 then you simplify this fraction to the lowest term....
divide both numbers by 2 which is 7/12...
i hope this helped :)
        
                    
             
        
        
        
Answer:
B
Step-by-step explanation:
Recall that if two functions, <em>f</em> and <em>g</em>, are inverses, then by definition: 

Hence, the graph of f(g(x)) should be simply <em>y</em> = <em>x</em>. 
Therefore, our answer is B, as both coordinates are equivalent for all three points.
