You're almost looking at the solution. Almost.
If it only said " r = 1 ", then that would be the solution right there.
But it says " | r | = 1 ", so there's a little more to it.
'r' can be either +1 or -1 and that equation will be a true statement.
So +1 and -1 are both solutions.
Answer:
?
Step-by-step explanation:
By difference I think you mean how far away from? I don't really know what you mean by this but I will try to help.
1/2-4=-3 1/2
2-(-3 1/2)=5 1/2
<u>-3 1/2</u>
5 1/2
Above is a fraction.
I hope that I helped. Sorry if it wasn't the answer you were looking for.
