Question

Guys please help me this is a system of equation word problem

Answer 1

The starting weight was 185, and the rate of change was -3 (per day).
.. w = 185 -3d . . . . . . d is the number of days, w is the weight in pounds


Evaluating this for d=7, we have
.. w = 185 -3*7 = 164
The point is represented by the ordered pair (7, 164).


The value on day 7 corresponds to the weight loss due to rejection. We might conclude the reaction to rejection was the cause of death.
