Hey guys please help!!
Advocard [28]

Answer:

<em>Yes</em>

Step-by-step explanation:

g(x) = - \frac{1}{4} x + \frac{1}{4}

y = - \frac{1}{4} x + \frac{1}{4} ....... <em>(1)</em>

<em>(1)</em> × 4

4y = - x + 1

x = - 4y + 1

y = - 4x + 1

f(x) = - 4x + 1

∴ f(x) and g(x) <em>are inverses</em>

Michael runs a distance of 5 1/4 miles in 45 3/4 minutes during a fade. At this rate, what is Michaels average speed in miles pe
ad-work [718]

Answer: Micheal's average Speed =6.885 miles per hour

Step-by-step explanation:

Speed= Distance /time

Given the distance he ran as  = 5 1/4 miles

And Time taken = 45 3/4 minutes

changing to hours becomes

60 mins = 1 hour

45 3/ 4 mins = 45 3/4 mins/ 60mins x 1hour

= 45.75 /60 =  0.7625hours

Therefore Micheal's average Speed= Distance /time

             =5 1/4miles / 0.7625hours = 5.25/ 0.7625

              =6.885 miles per hour

approximately 7 miles/hour.
