Is y = x + 1 a function, a one-to-one function or is it just a relation?
y = x +1 is a function because every element in the domain has onely 1
element in the range (which is 1 greater than said element in domain).
Additionally, if you graph this equation you can see that it passes the
vertical line test.
Step-by-step explanation:
LCM of 18, 30 and 42
= 2×3×3×5×7

Question:
How is subtracting -4x from 9x similar to subtraction -4 from 9?
Answer:
If both of them have the same variable lets say this:
2a + 2a = 4a
Just add 2 + 2 and then keep the a later at the end since they both have the same letter.
So in this case, it will be the same as subtracting -4 from 9 because they both have the same variables so the x would stay the same:
-4x + 9x = 5x
would be the answer.
Hope this helped!
