|x|=4 x = 0 and x = 4 x = 4 and x = −4 x = 4 x = −4 What are the two correct equations?

myininaya (myininaya):

what gives you a distance of 4 from 0?

OpenStudy (anonymous):

x = 4 and -4 Absolute value means that if we plug in a negative number it becomes positive. Treat it as the "distance" to zero. Thus 4 and -4 would make this true.

myininaya (myininaya):

the distance of 0 to 0 is 0 which is not 4 right?

OpenStudy (buttermequeasy):

Right...

myininaya (myininaya):

what is the distance from -4 to 0?

myininaya (myininaya):

what is the distance from 0 to 4?

myininaya (myininaya):

both of the answers to my question is 4 units

myininaya (myininaya):

so |x|=4 is asking what gives me distance 4 from 0?

myininaya (myininaya):

-4 or 4 x=-4 x=4 /\ | both of the inputs will give us distance 4 from 0

OpenStudy (buttermequeasy):

Oh okay....
