now, the angle of θ, can only have a "y" value that is positive on, well, y is positive at 1st and 2nd quadrants
and "x" is positive only in 1st and 4th quadrants
now, that angle θ, can only have those two fellows, "y" and "x" to be positive, only in the 1st quadrant, and also both to be negative on the 3rd quadrant.
and that those two fellows, can also be both negative in the 3rd quadrant
3/1 = 3, and -3/-1 = 3
so, the solutions can only be "3", when both "y" and "x" are the same sign, and that only occurs on the 1st and 3rd quadrants
Let the time Larry spend reading be x and the time he spend watching TV be y. Then
x + y ≤ 4 . . . (1)
x ≥ y . . . (2)
The
graph represents two straight lines with one line passing through
points (0, 4) and (4, 0) and the other one passing through points (0, 0)
and (2, 2). The two lines intersects at point (2, 2) with the portion
of the graph bounded by the x-axis shaded.
