Answer:

Step-by-step explanation:

The given equation is y=3x+9.

To find the inverse of the function we switch x and y then solve for y .This will give us the inverse of the function.

Switching x  and y in the given equation we have :

x=3y+9.

Adding 9 both sides :

x-9=3y.

With y term 3 is multiplied .Dividing both sides by 3 we have:

\frac{x}{3} -3=y

Or y=\frac{1}{3} x-3

spayn [35]

Answer:

10 milligrams of Medication A

Step-by-step explanation:

We'll write proportions/ratios for this:

20:16 is the usual proportion, and x:8 is this week's dose. The ratio from A to B has to be equal, so

20/16 = x/8

Cross-multiply:

(20)(8) = (16)(x)

160 = 16x

divide both sides by 16

x = 10
