X + y = 12 . . . . . . . . (1)
x - 3y = -30 . . . . . . . (2)
(1) - (2): 4y = 42
y = 10.5
        
                    
             
        
        
        
Answer:  d) (3, 3)
<u>Step-by-step explanation:</u>
Inverse is when you swap the x's and y's.
Let's look at the points and find their inverse:
   f(x)           f⁻¹(x)
(0, -2)  -->  (-2, 0)
 (1, -1)   -->   (-1, 1)
 (2, 0)  -->   (0, 2)
 (3, 3)   -->   (3, 3)        f(x) = f⁻¹(x) so this is where they intersect!
 
        
             
        
        
        
A(n,s)=(ns^2)/(4tan(180/n)), n=number of sides, s=side length
A(8,4.6)=(8*4.6^2)/(4tan22.5)
A(8,4.6)=42.32/tan22.5 m  (exact)
A(8, 4.6)≈102.17 m^2  (to nearest hundredth of a square meter)
