Question 548322: First of all I would like to know if the input depends on the output,,and this word problem,,,the recommeded weight of an adult male is given by the formula W=5.5h-220 where W represents weight in pounds and h represents height in inches,,,I am asked to determine the hight of a man whose recommended weight is 210lbs,,the determine the weight of a man who is 75 inches tall, then I am asked would 180 be a reasonable value for the input and why....Thank-you

You can put this solution on YOUR website! Yes, the input will determine the output in this linear equation in both cases.
W = 5.5h - 220
To find the height of a man whose weight is 210, replace W with 210 and solve the equation for h.
To find the weight of a man whose height is 75 inches, replace h with 75 and solve for W.
Try it out. You'll be glad you did!
