Every input(x) has only one output(y)
Emily and Marie can’t have the same birthday in this so it’s not a function
This is the fundamental zero additive rule
x - 0 = x
which means that for the set of real numbers, there exist a number such that if added (or subtracted) from any other will not affect such number.
The 2nd step, you're supposed to combine like terms (20h and 2h) but not the 5 because it doesn't have a h next to it.
Answer:
<u>Linear</u>
y=-x
<u>Non linear</u>
Step-by-step explanation:
Linear equations have the highest degree to be 1.
Therefore y=-x is linear.
The degree of this equation is 2.
It is non-linear
is also linear.
