Answer:

f(g)=25g

Step-by-step explanation:

Let g be the number of gallons so f(g) is the number of miles traveled per g gallons.

We know for our problem that Brian's car gets 25 miles per gallon. Since the gallons is represented by g, his car will travel a total distance of 25g (where g is the number of gallons.

We also know that the total distance is given by f(g), so we can put the two expressions together to get our function:

f(g)=25g

Let's check:

- If he uses 1 gallon (g=1), so

f(1)=25(1)

f(1)=25 miles

He will travel 25 miles with one gallon.

- If he uses 2 gallons (g=2), so

f(2)=25(2)

f(2)=50

He will travel 50 miles with two gallon.

What is the value of X if 9^x^-^1-2=25?
nadezda [96]

Answer:

\frac{5}{2}

Step-by-step explanation:

First, add two to both sides to get 9^{x-1}=27

There are two ways to solve this from here

  1. Think about what power you would have to raise 9 to to get to 27. 9^{\frac{1}{2}} = 3 and 3^3=27. So, multiplying the powers (because it is a power to a power) you get 9^{\frac{3}{2}}=27. This means that x - 1 = \frac{3}{2} or x = \frac{5}{2}.
  2. Take the log of both sides.

This gives us \log_9(27)=x-1\\\log_9(27)+1=x\\\log_9(3^3)+1=x\\3\log_9(3)+1=x\\3(\frac{1}{2})+1=x\\\frac{3}{2}+1 = x\\\\\frac{5}{2} = x
