1) You divide all the numbers that need to be divided
2) Move constant to the right
3) Add your numbers
And it will get you your answer = y=10.9
Here’s another answer if you didn’t understand the other one
Divide your numbers- y-4/10=21/2
Move constant to the right- y-0.4=10.5
Add the numbers- y=10.5+0.4
Hopefully that helped :)
Answer:
C) {(3, 4), (3, 5)}
Step-by-step explanation:
We know that,
<em>'Function is a relation in which every element of the domain is mapped to a unique element in the co-domain'.</em>
So, we get that,
<em>In the ordered pair (x,y), the if 'x' is mapped to two values say y and z, then for the relation to be a function, y must be equal to z.</em>
So, according to the options, we see that,
In option C i.e. the relation {(3,4), (3.5)}, we have that, 3 does not have unique image i.e. it is mapped to 4 and 5 both.
Thus, this relation does not satisfy the definition of a function.
So, option C will not represent a function.
