Answer:
-∞ < y ≤ 12
Step-by-step explanation:
The range is the vertical extent of the graph of the function. Here the function values range from -∞ to a maximum of about 12. An appropriate description is ...
-∞ < y ≤ 12
Supplementary angles = Angles that add up to 180°.
∠5 + ∠7 = 180° ← supplementary angles
∠1 = ∠5
Since ∠5 + ∠6 = 180°
⇒ ∠1 and ∠6 will also be 180° . ← supplementary angles
--------------------------------------------------------------------------------------
Answer: ∠5 + ∠7 (Answer D) and ∠1 + ∠6 (Answer A)

Answer: Slope: -1.6
Use the slope formula
substitute point values in the formula
(10 -2)
- like this: m = ----------
(1 - 6)
Simplify each other side of the equation
- simplified: 8/-5
m: - 1.6
The coordinates of the focus are (3,0)
