The number of milligrams of a certain medicine a veterinarian gives to a dog varies directly with the weight of the dog. if the veterinarian gives a 30-pound dog \frac{3}-{5} milligram of the medicine, which equation relates the weight, w, and the dosage, d?

Step-by-step explanation:

Let

w be the weight of the dog

and

d be the dosage given to the dog

As both of them are directly proportional

d ∝ w

Whenever the proportion symbol is removed from proportion, a proportionality constant is introduced.

So,

d = kw      Eqn 1

As we are given the values of d and w, putting the values

3/5 = 30k

So,

k = 1/50

Putting

K=1/50 in Eqn 1

So d = 1/50 * k relates dosage and weight ..

..

step-by-step explanation:

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
