You need to make 2 equations one for the real part of the complex number and another from the imaginary part . So for Q 9:-
2x = 4 so x = 2
and x + y = -5
so 2 + y = -5
y = -7
so the answer is x = 2 and y = -7
10.
(x - iy) + (y + xi) = 1 - 5i
x + y + xi - yi = 1 - 5i
x + y = 1
x - y = -5
adding:-
2x = -4
so x = -2
-2 - y = -5
y = 5-2 = 3
So x = -2 and y = 3
Pretty simple equation, where we need to find the number of books. If it is 2$ each day per book
72/9 = 8$ per day is the late fee paid
So if each book is 2$, then we can assume
8/2 = 4 books
So equation is
“# books = (amount paid)/(days * per day payment)”
Answer: Point slope form is y-y1=m(x-x1)
Step-by-step explanation:
Here y1=4
x1=-11
m i.e slope=-2
And there you go.
