Answer:
Step-by-step explanation:
The graph of a function and its inverse will always reflect through the line
y = x.
This is because a function has a specific set of coordiates, (x, y). That function's inverse has a set of coordinates that flips the x and y coordinates. For example, if a function has a set of coordinates (0, 1), (2, 3), (4, 5) then its inverse will have the coordinates (1, 0), (3, 2), (5, 4). If you plot the function's points and then the inverse's points in the same plane (meaning on the same graph) and connect the dots, you will see that the function and its inverse are reflections of each other through y = x. Below is an example of this. The dotted purplish line is the line y = x.

The answer is: " 270 minutes " .
__________________________________________________________
→ There are "270 minutes" in "4 hours and 30 minutes" .
__________________________________________________________
Explanation:
__________________________________________________________
Method 1):
__________________________________________________________
Note: 60 minutes = 1 hour (exactly);
30 minutes = ? hr ? ;
→ (30 minutes) * (1 hr/ 60 minutes) ;
= (30/60) hr = (3/6) hr = (3÷3)/(6÷3) hr ;
= "
hr " ;
or; write as: " 0.5 hr " .
_________________________________________________________
So "4 hours & 30 minutes" = 4 hours + 0.5 hours = 4.5 hours.
→ 4.5 hours = ? minutes ;
The answer is: " 270 minutes" . 4.5 hours *
;
= (4.5 * 60) minutes = " 270 minutes " .
→ The answer is: " 270 minutes ".

Method 2)
___________________________________________________________
"4 hours and 30 minutes" = <u> ? </u> minutes " .
___________________________________________________________
→ " 4 hours = <u> ? </u> minutes " ;
→ 4 hr . * = (4 * 60) minutes = 240 min. ;
→ There are " 240 minutes in 4 hours" .
→ To find the number of "minutes" in "4 hours and 30 minutes" ;
→ we takes the number of minutes in 4 hours—which is "240 minutes"—and add "30 minutes" to that number; as follows:
→ " 240 minutes + 30 minutes " ;
to get: " 270 minutes " .
_______________________________________________________
→ There are "270 minutes" in "4 hours and 30 minutes" .

The answer is: " 270 minutes " .
