Answer:
The x's cancel so definitely is choice C: 1/9
Step-by-step explanation:
We have root( 1/(x^2) ) * root ((x^2) / 81)
simplifying this we get as follows:
root( 1/(x^2) ) * root ((x^2) / 81)
= 
* 
= ( 1/x ) * (x/9)
the x's cancel
= 1/9
choice C 1/9
X=3 and y=-5/2. Here is why, when we do 7x+5x that gives us 12x. -2y+2y=0 and then we have 16 plus 20 which gives us 36. Now we gotta isolate x which right now we have 12x=36. Therefore divide by 12 to get x alone, which 36 divided by 12 is equal to 3. X=3. Plug it back into the equation, 7(3)=21 plus 2y=16. Subtract 21 from both sides 16-21 is equal to -5. Then 2y=-5 divide by 2 on both sides you will have -5/2=y or y=-5/2. Hope this helps!
