Question 1050714
<font color=black size=3>



First let's find the value of {{{f(273)}}}



{{{f(x) = 67x-125}}}



{{{f(273) = 67(273)-125}}} Replace every 'x' with 273



{{{f(273) = 18291-125}}}



{{{f(273) = 18166}}}



----------------------------------



Now let's find the value of {{{f(195)}}}



{{{f(x) = 67x-125}}}



{{{f(195) = 67(195)-125}}} Replace every 'x' with 195



{{{f(195) = 13065-125}}}



{{{f(195) = 12940}}}



----------------------------------



We have the information we need. We can now compute what the book/teacher is asking.



{{{(f(273) - f(195))/(273-195) = (18166-12940)/(273-195)}}}



{{{(f(273) - f(195))/(273-195) = 5226/78}}}



{{{(f(273) - f(195))/(273-195) = 67}}}



----------------------------------



The final answer is <font color=red size=5>67</font>
