The table of values below represent an exponential function, write an exponential equation that models the data, answers are y=23(0.7) x, y=16.1(1.7) x, y =11.27(0.7) x, or y =1+ 27(1.3) x

step-by-step explanation:

6 cm

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.
