Answer:

b. y=sec(x/3) and y=-1

Step-by-step explanation:

sec(x/3) + 4 > 2 − sec(x/3)

2 sec(x/3) > -2

sec(x/3) > -1

Graph y = sec(x/3) and y = -1.

Does anyone know the equation to this graph
Eduardwww [97]

Answer: The equation of this graph can be written in slope intercept form which is what I am assuming you want.  If you do not want that form you can convert to any other form that you so desire.  The slope intercept equation for this graph would be y = -1x - 2.  The -1 is the slope of the line and the -2 is the y intercept.

Show that (0, 0) is equidistant from (1, 2), (-1, -2) and (2, 1).​
Len [333]

Step-by-step explanation:

1) if (0;0) if point A, (1;2) is point B; (-1;-2) is C, (2;1) is D, then

2) the vector AB is (1;2); vector AC is (-1;-2) and vector AD is (2;1), then

3) the length of AB, AC and AD are:

|AB|=\sqrt{1^2+2^2}=\sqrt{5};

|AC|=\sqrt{(-1)^2+(-2)^2}=\sqrt{5};

|AD|=\sqrt{2^2+1^2}=\sqrt{5}.

4) if the lengths above are equal, then it means that (0, 0) is equidistant from (1, 2), (-1, -2) and (2, 1).
