Answer:
C.
Step-by-step explanation:
(x+yi)+(4+9i)=9-4i
x+yi+4+9i=9-4i
x+4+yi+9i=9-4i
Comparing the real and imaginary part we get:
x+4=9 OR y+9=-4(imaginary portion)
x=9-4 OR y=-4-9
x=5 OR y=-13
Answer:
I don't know the answer to this question.
I have some answers but not all of them lol so
5a) -2/3
5c) y = -2/3 + 2
6a) x intercept point is (4,0) and y intercept point is (0,2)
6b) -1/2
6c) im pretty sure it's y = -1/2 -2
T is equal to or more that 3
