Select the characteristics of a line that apply to the linear parent function.
The domain is all real numbers.
The y-coordinate is equal to the x-coordinate at each point on the graph.
A graph of the function is a straight line.
I Certain real numbers cannot be returned by the function.
The function can be increasing or decreasing.
Only positive numbers can be used as input.
The range is all real numbers.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
