Initially, a spinner points west. Chenille moves it clockwise 2 1/4 revolutions and then counterclockwise 3 3/4 revolutions. In what direction does the spinner point after two moves?

East

Step-by-step explanation:

Given

A spinner initially pointing towards west is made to move revolutions clockwise and  revolutions counterclockwise.

After one complete revolution pointer points at the same direction.

So, the net movement of the spinner is

That is 1 and half-revolution counter clockwise

After 1 revolution, direction is same, but after half revolution it points towards east.

The final direction is east.

how to award brainliest:

you must wait until 2 people answer to award brainliest. i'm pretty sure that it should be next to the "" and "comments" buttons.  

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
