Answer:
2y is just 2 times y, so subtracted it would be 1y and 1y is just y.
-x^2 + 9 - 3x^2 - 11x + 4
-4x^2 - 11x + 13
Answer: <span>D. Are perpendicular
</span><span>4x=3y+23 slope = 4/3
</span><span>4y+3x=-19 slope = -3/4</span>
Answer: (0, -6)
Step-by-step explanation:
The center is the midpoint of the diameter, meaning that the coordinates of Y must be (0, -6).
