Question

What is the opposite of - 2 over 5

Answer 1

The opposite of -2/5

Well, the opposite would just be everything switched around!

So, our negative would become a positive, and the 5 and 2 would be switched around! :)

So, with the negative turned into a positive and with the numbers switched around, our answer is :

A) 5/2


What is I -10 I  ?

Well, the absolute value of something is basically just the distance of that number from 0.

So, if you were to plot -10 on a number, and then counted the numbers it took to get back to 0, it would be 10!

So, the absolute value of -10 is 10


Simplify : 3x² + I -4 I

First, we find the absolute value of -4.

An easier way to find the absolute value of something is to just take out the negatives, and switch it with a positive! So, if you are looking for the absolute value of a negative, simply turn it into a positive. However, if you are looking for the absolute value of a positive, it stays positive.

So, the absolute value of -4 is 4.

So, now we have : 

3x² + 4

Because you only asked for this simplified, this is the simplest it can be simplified.

~Hope I helped!~
