Hello can anyone please help me find the answer to this.

Step-by-step explanation:

No.  Starting out, Maria walks away from home at a constant speed (which we recognize because the graph is at first a straight line).  Then she stops  for  a little while, turns around and heads for home at the same speed as before (positively sloped graph), level graph, negatively sloped graph).

2? if not the correct answer you might need to provide more information

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.
