You ride your bike at an average of 12 miles per hour on the way to school, and at an average of 15 miles per hour on the way ho

-Dominant- [34]

Answer:

2.44 miles

Step-by-step explanation:

Give the following :

Average miles to school = 12 miles per hour

Average Miles from school = 15 miles per hour

Total ride time : ( time to school + time from school) = 22 minutes = (22/60) = 0.3667

Recall:

Speed = distance / Time

Time = distance / speed

Let distance = d

For the scenario described :

d/12 + d/15 = 0.3667

(5d + 4d) / 60 = 0.3667

5d + 4d = 22

9d = 22

d = 22/9

d = 2.44 miles

Step-by-step explanation:

Move it it up 4 and then find your x intercepts.

Find the x intercepts.

$-x^2 + 4 = 0$

<u>Move the 4 over to the right</u>

$-x^2 = -4$

<u>Divide out the - </u>

$\frac{-x^2}{-} = \frac{-4}{-}$

$x^2 = 4$

<u>Take the square root of each side</u>

$\sqrt{x^2} = \pm \sqrt{4}$

$x = \pm \sqrt 2$

Our x intercepts are at (-2,0) (2,0)
