Suppose the function f(x) = 0.035x represents the number of u. s. dollars equivalent to x russian rubles, and the function g(x) = 90x represents the number of japanese yen equivalent to x u. s. dollars. write a composite function that represents the number of japanese yen equivalent to x russian rubles. show your work.

g(f(x)) = 3.15x

Step-by-step explanation:

To find the number of Japanese yen equivalent to x russian rubles, we need to put one function into another.

If we take f(x) and put in into g(x), we will get Japanese yen in terms of rubles. Thus,

g(f(x)) = 90 (0.035x)

g(f(x)) = 3.15x

THis is the composite function which represents the number of Japanese yen equivalent to x Russian Rubles.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
