1) replace "f(x)" with "y:"

y = 7 / (6x -5)

2) Interchange "x" and "y:"

x = 7 / (6y - 5)

3)  Solve this new equation for y:

x(6y - 5) = 7, or 6xy - 5x = 7, or      6xy = 7 + 5x.

                 7+5x
Then y = ------------
                   6x
                                -1
4) Replace y with " f   (x)."

  -1            7+5x
f     (x) = -----------   (answer)
                    6x

Sliva [168]

Answer:

Step-by-step explanation:

GIRL! You should add diagrams to these types of questions. It would really help

That 10cm does not mean point C is 10cm. It means the line AB is 10 cm in total.

And since point C is the midpoint, which means that point C cuts the line AB in half, that makes AC = 5cm

A hiker climbs a 5-mile trail up a mountain in 2 hours. On the return trip downhill, she walks the same trail and returns to her
Ivahew [28]

Answer:

3.33 miles per hour

Step-by-step explanation:

The total distance traveled by the hiker is 5 * 2 = 10 miles, and the total time travelled is 2 + 1 = 3 hours.

So, to find the average speed of the entire trip, we can use the formula:

distance = speed * time

With distance = 10 and time = 3, we have:

10 = speed * 3

speed = 10/3 = 3.33 miles per hour.
