Answer:
Solid Line, Shade Above
Explanation:
Given:
The second inequality in the system is:
The intercepts of the boundary line (y=x-4) are (0, -4) and (4,0).
Since the inequality has an equal to sign attached, we use a solid line.
At (0,0)
Since the inequality 0≥-4 is true, shade the side that contains (0, 0) as shown in the graph below:
So, we use a solid line and shade above the boundary line.
This happens whenever the terminal point of
Meanwhile,
since you already know sine is positive. Cosine is positive when the angle lies in the first or fourth quadrant.
Sine and cosine are both positive only when
