jeka57 [31]

Answer:

C

Step-by-step explanation:

Hose A:

60 gallons every 15 minutes mean:

60 / 15 = 4 gallons per minute

For Hose B:

If we put x = 1, we can find gallons (y)  per minute (x)

y = 3 x

y = 3(1)

y = 3

That means 3 gallons per minute

Thus, the rate of Hose A is 1 gallon per minute more than the rate of Hose B. Option C is correct.

Find the inverse of g(x)=1/3x - 7 and then find its domain and range if you can show steps that would be gladly appreciated than
Schach [20]

Answer:

g-1(x) = 3(x + 7).

Domain is All Real values of x.

Range is All Real values of the function.

Step-by-step explanation:

Let y = 1/3 x - 7

1/3 x = y + 7

Multiply both sides by 3:

x = 3(y + 7)

So the inverse of g(x) = g-1(x) = 3(x + 7).

Domain is All Real values of x.

Range is All Real values of the function.
