What is the average rate of change of the function on the interval from x=0 to x=2?
f(x)=250(0.5)^x
enter your answer in the box as a decimal.
my answer is -187.5 i was wondering if any of you could check it.

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.

the answer is -6

step-by-step explanation:

the answer is -6 because its next to the variable m
