lisov135 [29]

Answer:

first option

Step-by-step explanation:

To obtain ( f ○ g)(x) substitute x = g(x) into f(x) , that is

f(\frac{1}{2x} )

= \frac{2}{\frac{1}{2x}+3 } ( multiply numerator/ denominator by 2x to clear the fraction

= \frac{2(2x)}{2x(\frac{1}{2x}+3) }

= \frac{4x}{1+6x}

Brandon 's time of arrival=

if 114 miles : 258 minutes

25/2 miles : ?
