Must it be a scatterplot or no?
Answer:
So x=4 and y=-5 would work.
Step-by-step explanation:
When you multiply complex conjugates, you get a real result.
Example:
I replace 
with -1 since 
.
is a real number (there is no imaginary part, no i).
So what is the conjugate of 4+5i?
4-5i
So x=4 and y=-5 would work.
A multiple of the complex conjugate would work as well.
This is still a real number; there is no imaginary part,no i.
Answer:
(5, -5)
Step-by-step explanation:
when you move up or down you only change the y axis
A
It is a first degree polynomial (aka linear because its highest power is 1) and it has two terms (2x and 8)
It does not have eight terms and is not a monomial (one term ie 3x^2)
Answer:
y=68.38172757
Step-by-step explanation:
Take the inverse cosine of both sides of the equation to extract
y from inside the cosine.
y=arccos(7/19)
y=68.38172757
The cosine function is positive in the first and fourth quadrants. To find the second solution, subtract the reference angle from
360 to find the solution in the fourth quadrant. y=360−68.38172757
y=68.38172757+360n,291.61827242+360n, for any integer n
