Step-by-step explanation:
line 1 and 2 : parallel
as line 2 is actually
6x + 2y = 8
2y = -6x + 8
y = -3x + 4
so, they have the same slope (factor of x).
line 1 and 3 : neither
the slopes -3 and 3 are not parallel not perpendicular (90°).
line 2 and 3 : neither
as line 2 is parallel to line 1, it has the same relationship to line 3 as line 1.
No because there are 7 presents and 6 pieces of ribbon
Answer:
Step-by-step explanation:
m=marta's rope
d=dilbert's rope
3d-10=m
m+d=120
Then you can substitute equation 1 into the second one
(3d-10)+d=120
3d-10+d=120
4d-10=120
4d=130
d=32.5
m+d=120
m+32.5=120
m=120-32.5
Answer:
The statement 'V(x) is a function'' is False.
Step-by-step explanation:
Let us make the table from the given mapping
x y
0 0
5 2
5 1
10 2
15 3
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.
If we observe the table, it is clear that x = 5 is repeated twice. It means the input x = 5 is duplicated.
In other words, we can not have duplicated inputs as there should be only 1 output for each input.
Therefore, V(x) is not a function.
Hence, the statement 'V(x) is a function'' is False.
