which equations support the fact that rational numbers are closed under addition?

select each correct answer.

√10+(−√10)=0

3√16+3√16=6√16

3√5+√5=4√5

1/2+0.5=1

The answer is 316−−√+316−−√=616−−√ and  12+0.5=1 trust me i took the test i got 100% YW

Step-by-step explanation:

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
