If f(x) = |x| + 9 and g(x) = –6, which describes the range of (f + g)(x)? (f + g)(x) > 3 for all values of x

(f + g)(x )< 3 for all values of x

(f + g)(x) < 6 for all values of x

(f + g)(x) > 6 for all values of x

step-by-step explanation:

try soting them out first

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.
