Answer:
Relations B and E do not represent the function.
Step-by-step explanation:
We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.
In other words, we can not have duplicated inputs as there should be only 1 output for each input.
If we closely observe relation B, and E i.e.
- B) {(3,4), (4,5), (3,6). (6,7)}
Relation 'B' IS NOT A FUNCTION
Relation B has duplicated or repeated inputs i.e. x = 3 appears twice times. we can not have duplicated inputs as there should be only 1 output for each input.
Thus, relation B is NOT a function.
Relation 'E' IS NOT A FUNCTION
Relation E has duplicated or repeated inputs i.e. x = 4 appears twice times. we can not have duplicated inputs as there should be only 1 output for each input.
Thus, relation B is NOT a function.
Therefore, relations B and E do not represent the function.
I think a but not sure but i hope i helped :D
Answer:
the number of blonde hair is 10
Step-by-step explanation:
The computation of the number of blonde hair is shown below;
Given that
Ratio of blonde to brunetees is 2:3
And, there is total of 25 students
So, the number of blonde hair is
= 25 × 2 ÷ (2 + 3)
= 25 × 2 ÷ 5
= 10
Hence, the number of blonde hair is 10
Answer:
A.
Step-by-step explanation:
B. y = 0x =0, or y =0, y is a constant.
A. y = 0.5x, in general from y = kx. It is the direct variation.
