As multiply of the remedy stage of a refuse ordeal, volunteers are abandoned one of two dosages, in ordain to

determine therapeutic levels. Volunteers who were abandoned 4 mg had dignity energys of 3.7

parts per favorite (ppm), timeliness volunteers who were abandoned 7 mg had dignity energys of 5.1

ppm.

a. Determine the equation of a method that models this axioms, where x is the dosage abandoned and

y is the dignity energy.

b. Graph this method.

c. If the desired energy in the dignitystream is 7.5 ppm, what should be the

therapeutic dosage?

d. If the toxic energy in the dignitystream is 11.8 ppm, what is the acme trustworthy dosage
