Model 3xfx Write the inverse of the rational function used to represent the situation in model 3, .

kompoz [17]

Make f(x) = y
y = (15x + 50)/(x + 5)
Swap the x and y and make y the subject again
x = (15y + 50)/(y + 5)
x(y + 5) = 15y + 50
xy + 5x = 15y + 50
xy - 15y = 50 - 5x
y(x - 15) = 50 - 5x
y = (50 - 5x)/(x - 15)
So inverse function f^-1(x) = (50 - 5x)/(x - 15)

a community bike ride offers a short 5.7 mile ride for children and families. the short ride is followed by a long ride, 5 2/3 t

VLD [36.1K]

38 miles

Further explanation

<u>Given:</u>

A community bike ride offers a short 5.7-mile ride for children and families.

The short ride is followed by a long ride, 5²/₃ times as long as the short ride, for adults.

A woman bikes the short ride with her children, and then the long ride with friends.

<u>Question:</u>

How many miles does she ride together?

<u>The Process:</u>

Let us make a pattern for the short ride:

$\boxed{5.7} \rightarrow in \ miles$

Let us do a multiplication on a fraction at first.

$\boxed{ \ = \frac{2}{3} \times 5.7 \ }$

$\boxed{ \ = \frac{2}{3} \times 5\frac{7}{10} \ }$

$\boxed{ \ = \frac{2}{3} \times \frac{57}{10} \ }$

We crossed out 3 and 57.

$\boxed{ \ = 2 \times \frac{19}{10} \ }$

$\boxed{\boxed{ \ = 3.8 \ }}$

Then we make a pattern for the long ride, 5²/₃ (five and two third) times as long as the short ride:

$\boxed{5.7}\boxed{5.7}\boxed{5.7}\boxed{5.7}\boxed{5.7}\boxed{3.8} \rightarrow in \ miles$

A woman bikes the short ride with her children, and then the long ride with friends. Let's calculate how many miles does she ride together.

The short ride: $\boxed{5.7 \ miles}$
The long ride: $\boxed{(5.7 \times 5) + 3.8 = 28.5 + 3.8 = 32.3 \ miles}$

$\boxed{ \ 5.7 + 32.3 = 38}$

Thus, she rides 38 miles together.
