Answer:
A function means that we get one input and one output. In this example that means for every x-value that we have, we only have one y-value.
Looking at the first option, we can see that there is no x-value that has more than one y-value which means that it is a function.
The rest of the options are seen with at least two values for one x-value in one of the points. Therefore, they wouldn't be considered a function leaving us with only option A as the solution.
This is how you do it :) let me know if you have any questions. Hope this helps :)
Answer: x = 7/3
Step-by-step explanation:
You join the X’s first which will give you
6x-14 = 0
Then you move the 14 to the right
6x = 14
Then you dived them and it give you 7/3

Answer:
21,600
Step-by-step explanation:
If in the coding system being used there are 6 vowels (A, E, I , O, U and Y)
Number of Consonants =26-6 =20
- First entry must be a consonant, therefore the first entry can be chosen in 20 ways.
- The second entry must be an integer 1 through 9, therefore the second entry can be chosen in 9 ways.
- The third entry must be one of the six vowels, therefore the third entry can be chosen in 6 ways.
- The last entry must be a consonant, therefore the last entry can be chosen in 20 ways.
Therefore:
Number of different possible ciphers =20*9*6*20
=21600
The answer is D but correct me if I’m wrong
