Answer: Simplifying the expression of the substraction of the two complex numbers we get 11-2i
Solution:
(5-5i)-(-6-3i)
Eliminating the parentheses: 5-5i+6+3i
Grouping similar terms: (5+6)+(-5+3)i
Adding the similar terms: 11+(-2)i = 11-2i

Answer:
B.
Step-by-step explanation:
The boundary line passing the origin has equation:
Since the lower half plane is shaded and the boundary line is solid, the corresponding linear inequality is:
The dashed line has equation,
Since the upper half plane is shaded, it is corresponding inequality is
+2x6 + 4x5 + x4 + 11x3 + 2x2 + 4x + 4
