X=12 that's is the answers
Well a percentage is basically a decimal. If we take the 20 and times it by 5,we can get a 100th of a decimal, 15/100= 0.15. Now we just change it to a percentage! 15%
Answer:
A
Step-by-step explanation:
X values cannot repeat in a function, 3 is used as an X value twice in A, and therefore cannot be a function.
If this is graphed, you can use the vertical line test, if a vertical line on any point goes through other points, it is not a function.
In this case, just check if X repeats.
