<u>Answer:</u>

<u>Step-by-step explanation:</u>
------------(1) (given)
-------------(2) (given)
so,
f(x) = h(g(x)) (given)
=
-----(from (1) and (2))
⇒
-----(taking g(x) = k)
⇒
is the function.
Only one because there is one variable and the combined coefficients of x are non-zero.
(0.75(x+40)=0.70(x+20), 0.05x=14-30=-16, x=-320)
