Respuesta :
The given linear function [tex]b(x)[/tex] is "-36", and the further calculation can be defined as follows:
linear function:
[tex]\to a(x)=26-12.4x[/tex]
when
x=5
so, putting the value of x into the above method:
[tex]\to a(5) = 26-12.4(5)\\\\ \to 26- 62.0\\\\ \to -36\\\\[/tex]
Since the function b(x) it also means that the functions have exactly one Solution at [tex]x=5 \\\\[/tex]
[tex]\to b(5)= -36\\\\ \to b(x)=-6(x+1)[/tex]
