That relation is a function because for every input you can tell the output without any ambiguity.
Answer: yes, it is a function.
Step-by-step explanation:
I am assuming you want x? if so :
5x+12=6x-10
-x = -22
x =22
if u wanted angle J :
plug x back in
5(22)+12 = 122
subtract 180-122
J = 58°
If there is no decimal you put it behind the last number, so it would be 47.68
I’m hoping this helps (but hopefully now you can give the brainliest to the person above)
I’m not very familiar with the square roots method but I believe you try and isolate the term that is squared.
