Answer:
It is both a relation and a function.
Step-by-step explanation:
Keith collected the names and ages of all of his classmates and organized them in the ordered pair (name, age).
Here, if we consider the name as the input and age is the output, then each and every different input there is a single output.
Because a single person can not have more than one age.
Therefore, it is both a relation and a function. (Answer)
Answer:
75%
Step-by-step explanation:
Here, we are asked to calculate the percentage of a trip that has been completed by Leigh.
Firstly, we identify the total length of the trip, this is 1470km. She stopped 370km from her destination. The length of the distance traveled is 1470km - 370km = 1100km
Now we proceed to calculate what percentage of the journey is this.
We calculate this by placing it over the total length multiplied by 100%
That would be
1100/1470 * 100 = 74.82 approximately 75%
I think AB is 3!!
i hope i’m right good luck ,:D
Answer: A
We could solve it but it's easier to just check the given solutions.
A. (7,1)
2y + 5 = 2(1)+5 = 7 = x, good
x/3-y = 7/3 - 1 = 4/3, good
B. (-3,8)
2y + 5 = 2(8)+5 = 21 not x=-3, doesn't check
C. Can't be true because we found a solution
D. Infinitely many solutions not true because the lines have different slopes
