Answer:
Option A.
Step-by-step explanation:
step 1
we know that
The equation of the solid line is

The solution is the shaded area above the solid line 
so
The equation of the first inequality is

step 2
The equation of the dashed line is 

The solution is the shaded area above the dashed line
so
The equation of the second inequality is

therefore
The system of inequalities could be 


 
        
             
        
        
        
1. (3 + xz)(–3 + xz)
2. (y² – xy)(y² + xy)
3. (64y2 + x2)(–x2 + 64y2)
Explanation
The difference of 2 squares is in the form (a+b)(a-c).
(3 + xz)(–3 + xz) = (3 + xz)(xz -3)
                            = (xz + 3)(xz - 3)
                           = x²y²-3xy+3xy-9
                           =x²y² - 3²
(y² – xy)(y² + xy) = y⁴+xy³-xy³-x²y²
                           = y⁴ - x²y²
(64y2 + x2)(–x2 + 64y2)= (64y²+x²)(64y²-x²)
                                       = 4096y⁴-64y²x²+64y²x²-x⁴
                                       = 4096y⁴ - x⁴
