In order to avoid heavy traffic, Antonio can drive home after working less than 7 hours (h < 7) or after working more than 9 hours (h >9). How can these inequalities be written as one statement?



7 < h < 9


7 > h > 9


h < 7 or h > 9


h > 7 or h < 9

To avoid heavy traffic, Antonio must work less than 7 hours OR more than 9 hours.

Mathematically, that means h < 7 OR h > 9.

Hence, the answer is C : h < 7 or h > 9.

Answer:

\(h<7\)  or  \(h>9\)


Step-by-step explanation:

Antonio can avoid traffic if he works for LESS THAN 7 HOURS or GREATER THAN 9 HOURS.

Is there any COMMON point in those 2 statements? Is there any number that satisfy BOTH LESS THAN 7 and GREATER THAN 9?

No! So inequality can't be written as one, rather as 2 statements with an "or" in between.

So we can write LESS THAN 7 as \(h<7\)  , and

GREATER THAN 9 as \(h>9\)


Hence, third choice is correct:

\(h<7\)  or  \(h>9\)
