Answer:
3
Step-by-step explanation:
If your talking about the x where it says 3x in, then
3x = 9
x = 3
D is the distance from moon to sun, and it's the hypotenuse of a right triangle.
Y is opposit to angle X
Sin (x) = y/d =
D = Y/sin(x)
Answer:
-2
Step-by-step explanation:
To find the slope of a line, you need to find the
between two points. I will be using the points (-3, 2) and (-1, -2).
= 
= 
= 
= -2
Given

To obtain the minimum value of y, we first take the derivative of y
The derivative of y is:

Equating

gives the minimum value we require.
Doing that, we have:

So that

Therefore, the minimum value is x = 3
