The answer is A, idk what the other person is talking about but it's A. I graphed it and it's A
The sum will have an x-term sumtimes ... whenever
the x-terms alone don't add up to zero.
Examples:
-- Two linear expressions:
y + x
and
y + 2x
The sum of the x-terms alone is (x + 2x) = 3x .
So the sum of the expressions has an x-term.
(y + x) + (y + 2x) = 2y + 3x .
_______________________________
Two different linear expressions:
y + 3x
and
y - 3x
The sum of the x-terms alone is (3x - 3x) = zero.
So the sum of the expressions doesn't have an x-term.
(y + 3x) + (y - 3x) = 2y .
If it’s true or false the answer is false.

ANSWER
EXPLANATION
We were given that,
This implies that,
We use the Pythagorean identity
to get,
We were also given that,
This means that,
This is because,
This angles are in the first quadrant so we pick the positive values.
The correct answer is D
