If f(x) = 7x − 1, what does f(12) represent? the value of x when (7x − 1) = 12 the value of (7x − 1) when x = 12 the value of 12 f(x) when x = 12 the value of f(x) when (7x − 1) = 12

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)

if x decreases by 4 then y increases by 10
