18)(x) = 2x-9
(fºg)(x) - 35x+31
(gof)(x) = -2x + 9
(fog)(x) = -2x+9
(fºg)(x) = -35% - 31
(gof)(x) = -35x+ 25
(gºf)(x) = -35% - 31
select the best answer from the choices provided

step-by-step explanation:

left be aligning the decimal points is required to not required see the number of digits to the right

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
