Explain the solution to |4w + 9| = –7

geerky42 (geerky42):

impossible for absolute value to be negative, unless imaginary number is involved somehow

OpenStudy (anonymous):

You're going to add seven to both sides. Then divide by 4. Then you're going to solve the problem again by finding w for a negative 2.

OpenStudy (genny7):

so if its a negative absolute value you cant solve for it?

geerky42 (geerky42):

none, I checked, there is no solution because |4w + 9| is always positive, regardless to what value w is, hence it cannot be equal to -7

geerky42 (geerky42):

so it cannot be solved...

OpenStudy (genny7):

okay thank you very much :)

myininaya (myininaya):

@geerky42 \[|a+bi|=\sqrt{a^2+b^2}\] so imaginary wouldn't work either but i think you are saying that and your post before the last

myininaya (myininaya):

in not and*

myininaya (myininaya):

|w|=positive or 0 for any complex number w

OpenStudy (genny7):

wait so you can solve w?

myininaya (myininaya):

No that isn't what I'm saying

geerky42 (geerky42):

yep, thats what i though.

geerky42 (geerky42):

no it cannot be solved @genny7

OpenStudy (genny7):

lol thanks just got a little confused
