Answer:

  • a = 5
  • b =
    \bf{5(1)/(7)}

Step-by-step explanation.


\bf \longrightarrow{f(x) = (1)/(x - 7) \: \: \: \: , \: \: \: g(x) = (1)/(x - 5) }


\bf \longrightarrow{f \circ g = (1)/( (1)/(x - 5) - 7) }

So we know
(a)/(b) , b ≠ 0


\bf \longrightarrow{so \: \: x - 5 \\eq0 \: \: , \: \: (1)/(x - 5) \\eq7} \\ \\ \bf \longrightarrow{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x \\eq0 \: \: , \: \: (1)/(x - 5) \\eq0 }\\ \\\bf \longrightarrow{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = 5 (1)/(7) } \\ \\ \bf \longrightarrow{and \: a < b }\\ \bf \longrightarrow{so \: a = 5 \: , \: b = 5(1)/(7) }
