A relation is a function if the value in its Domain does not occur more than once. This means each domain value is paired with exactly one value of range.
In the given scenario, the domain is the students (e.g name of a student) and the function returns the date of birth of the student. A student can have only one date of birth. So it is not possible that a value in Domain(i.e. a student) is paired with more than one date of births.
Therefore, we can conclude that the given relation describes a function.
can be written as follows:
since
and
are always positive, except for x=2 and y=-1, when they become 0,
the minimum value of this expression is when x=2, and y=-1, that is -5
Answer: -5
Question
Why do it say incorrect answer?
But that’s a trinomial equation.
Answer:
A square unit is a small area of a square used to find a total.
Step-by-step explanation:
X + y = 38
2x + 5y = 100
Where x is how many 2 pointers there were on the test and y how many 5 pinters there were
Elimination method:
2x + 2y = 76
2x + 5y = 100
2x - 2x + 2y - 5y = 76 - 100
-3y = - 24
y = 8
Apply it to the equation to get x
x + 8 = 38
x = 30
30 two pointers
8 five pointers
