I think C . But don't count on it
OpenStudy (welshfella):
Do you know what the vertical lines around ax - b mean?
OpenStudy (knov):
We know that C is a real number and C>0.

which is |ax-b| is a positive integer.So it can't be |ax-b|<-c. And we also know that D and C are not the answers since it;s obvious.
OpenStudy (anonymous):
it would be B because the signs have to be going the same direction
OpenStudy (knov):
think about it. can ax-b be > than C and < than C at the same time ?
OpenStudy (knov):
-C*
OpenStudy (knov):
we are looking for an inequality to |ax-b|>C

ax - b can be negative because we have the absolute value here |ax - b|
OpenStudy (knov):
ax-b can't be negative since c>0
OpenStudy (knov):
and ax-b>C
OpenStudy (anonymous):
it was D
OpenStudy (welshfella):
just as an exercise
use
|2x - 1! > 3
and see which of the options fit the numbers

yes D is correct
OpenStudy (knov):
@FaiqRaees i don't get you.
OpenStudy (welshfella):
2x - 1> 3 gives 2x > 4 x . 2
2x - 1 < -3 gives 2x < -2 x < 1
if you check bak you#ll see that fits the original equality |2x - 1| > 3
