Answer:
first option
Step-by-step explanation:
3x - 7y and - 7y + 3x are equivalent expressions
3x is positive and - 7y is negative
As long as the signs on their coefficients do not change then they can be reversed, that is
3x - 7y = - 7y + 3x

Answer:
Step-by-step explanation:
Complex numbers:
The following relation is important for complex numbers:
Zeros of a function:
Given a polynomial f(x), this polynomial has roots 
such that it can be written as: 
, in which a is the leading coefficient.
Has zeros −19 and −i
If -i is a zero, its conjugate i is also a zero. So
Output of 40 when x=1
This means that when 
. We use this to find the leading coefficient a. So
The polynomial is:
2x +2 when x = 4 = 10 -1 = 9?
