The same input is being mapped into two outputs, so this is not a function.
<h3>
Does the table represent a function?</h3>
A function is a relation that maps elements from the domain into elements from the range. Such that each element of the domain can be mapped into only one element of the range.
Here we have the table:
x y
4 2
3 3
4 5
5 6
7 7
As you can see, the input x = 4 appears two times, first it is mapped into y = 2, and then it is mapped into y = 5.
Then this table does not represent a function.

Answer:
Step-by-step explanation:
we know that
In this problem ABCD is a rectangle
so
DC=AB
BC=AD
Let
BC ---> the length of rectangle
DC ---> the width of rectangle
we know that
The perimeter of rectangle is equal to
we have
so
simplify
----> equation A
----> equation B
substitute equation B in equation A
Solve for BC
Combine like terms
Divide by 3 both sides
<em>Find the value of DC</em>
----> 
Remember that
DC=AB
therefore
Answer:
i think it is b(-22)

Answer:
x=0
y=-21/7
Step-by-step explanation:
Let the two unknown be x and y
x+y=-7...(1)
x-y=14...(2)
From (1) make x the subject of formula
x=-7-y...(3)
Substitute (3) into (2)
-7-y-y=14
-7-2y=14
Add 7 to both sides
-2y=21
Add both sides by-2
y=-21/2
Substitute the value of y into (3)
x=-7-(-21/2)
x=-7+21/3
Lcm
x=-21+21/3
x=0/3
x=0
D = m/v
V = 2•2•2 = 8cm^3
D = 12/8 = 1.5g/cm^3
Answer is B
