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.

A Prime Number can be divided evenly only by 1, or itself.

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

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 = $\frac{5}{2}$ .
Take the log of both sides.
