@Shadow

silvernight269:

Someone just pls help me?!

Ultrilliam:

Egh alright lemme give this my best shot

Ultrilliam:

Is this a true false question?

Ultrilliam:

|-2c-3| This is absolute value, so you would eliminate negatives |2*c-3|, 2*0-3 is still above -4 so it would be true if so. I probably did this wrong though. @Vocaloid

silvernight269:

No it’s not a true or false question I have to solve it

Ultrilliam:

Then I have no idea x.x Vocaloid should be able to help when she sees the question

madisonthedoll:

Vocaloid:

Consider the absolute value expression as a whole |A| > -4 This is always true because the absolute value of anything is always on-negative Therefore c can be anything (all real values)

Vocaloid:

*non-negative

AnimeLuver10023:

In order to solve this all we have to do is break it down into two small equations: -2c - 3 > -4 and -(-2c - 3) > -4 When we solve both of them we get our answers (so there is more than one answer)

AnimeLuver10023:

The answers would be c < 1/2 and c > -7/2
