Answer: If you take the square root of a number that is not a perfect square, it is going to be irrational. And then if you just take that irrational number and you multiply it, and you divide it by any other numbers, you're still going to get an irrational number. So square root of 8 is irrational. You divide that by 2, it is still irrational.
Step-by-step explanation:
Answer:
The choices were typed wrong, but we can find the inverse of each option.
For function 
the inverse is the same function 
, because an inverse of a function is where their composition gives the independent variable as unique result.
If we do that with each function, we have:
; where and , we have
So they are inverse.
For 
its inverse would be 
, because
For 
, its inverse is 
, because
For 
, its inverse is 
, because
There you have all inverses. Basically, if their composition results in 
, that means they are inverse.
Answer:
no

3y+3 doesnt equal 9y+3
Answer:
190 degrees
Step-by-step explanation:
let's ignore the 10 degrees first. you see the half circle with the angle on it, that is called a supplementary angle. all supplementary angles are equal to 180 degrees. so we know that that is already 180 degrees, then you have to add back the 10 degrees to get the full angle. so you add 10 to 180 and get 190 degrees.
3/5 into decimal form is <em>0.6</em>
