The path of two bumper cars can be represented by the functions x + y = –5 and y = x2 – x – 6. At which locations will the bumpe
Alex Ar [27]

Equaling the equations, it is found that the cars hit each other at: (-1,-4) and (1,-6).

---------------------------------

For the first car, we have that:

x + y = -5

Thus:

y_1 = -5 - x

---------------------------------

For the second car:

y_2 = x^2 - x - 6

---------------------------------

They meet at the the values of x for which:

y_1 = y_2

Thus:

-5 - x = x^2 - x - 6

x^2 - 1 = 0

x^2 = 1

x = \pm \sqrt{1}

x = \pm 1

  • When x = 1, they meet at y = -5 - 1 = -6
  • When x = -1, they meet at y = -5 - (-1) = -5 + 1 = -4

Thus (-1,-4) and (1,-6).

I need help on the second one
Nady [450]

Answer:

See explanation

Step-by-step explanation:

First, let's convert feet to miles.

\dfrac{63,756 \text{ feet}}{1}\cdot \dfrac{1 \text{ mile}}{5,280 \text{ feet}}=12.075\text{ miles}

Next, let's convert minutes to hours.

\dfrac{70 \text{ minutes}}{1}\cdot \dfrac{1\text{ hour}}{60\text{ minutes}}=\dfrac{7}{6}\text{ hours}

Finally, let's find the unit rate.

\dfrac{12.075\text{ miles}}{\frac{7}{6}\text{ hours}}=10.35\text{ mph}

Hope this helps!
