A line passes through the points (3, 21) and (6,24). write a linear function rule in terms of x and y for this line

answer: asdfghjkl,mnbv

step-by-step explanation:

hi! i think the answer is 1/2 : )

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.
