So walked 4/5 mile in a 4/9 h so just use the rule of 3 simple
60 minutes ------ 1 hour
x min. ----------- 4/9 h
--------------------------------
x = 4/9 *60/1 = 240/9 = 26,6 min.
4/5 mile -------in 26,6 min.
1 mile -------- x min.
-----------------------------
x = 1*26,6/(4/5) = 26,6 /(0,8) = 33,25 min.
1 mile ..... 33,25 min.
x miles ----- 60 min.
---------------------------
x = 60/33,25 = 1,8 miles
so their unit rate in miles per hour will be 1,8 miles / hour
hope this will help you
Answer:
2 large boxes, 3 small boxes
Step-by-step explanation:
The correct answer is D.
In order to solve for a function's inverse, you must start by switching the x and f(x) values. Then you solve for the new f(x). Once you have done that, you'll be left with the new function, which is the inverse of the original. See the work below for how this one will be solved.
f(x) = 
----> Switch the x and f(x)
x = 
----> Now subtract the 5 from both sides.
x - 5 = 
---> Now square both sides.
= f(x) - 1 ----> Now add 1 to both sides.
+ 1 = f(x)
And now that you have something equaling f(x), you can change the order and match it up to answer D.
f(x) = + 1
