Which relationship is a direct variation?
Setler79 [48]

Option A is the relationship which shows a direct variation.

Step-by-step explanation:

The direct variation is a relationship between two variables in which one is the multiple of the other. It is given by the relation

\frac{y}{x}=k

Option A:

For x=2 and y=1,

\frac{y}{x}=\frac{1}{2}

For x=4 and y=2,

\frac{y}{x}=\frac{2}{4}= \frac{1}{2}

Since, the constant k is equal for all the values of x and y in the table, this relationship is a direct variation.

Option B:

For x=2 and y=4,

\frac{y}{x}=\frac{4}{2}= 2

For x=4 and y=16,

\frac{y}{x}=\frac{16}{4}  =4

Since, the values of constant k is not equal for all the values of x and y in the table, this relationship is not a direct variation.

Option C:

For x=1 and y=3

\frac{y}{x} =\frac{3}{1} =3

For x=2 and y=5

\frac{y}{x} =\frac{5}{2}

Since, the values of constant k is not equal for all the values of x and y in the table, this relationship is not a direct variation.

Option D:

For x=1 and y=-1

\frac{y}{x} =\frac{-1}{1} =-1

For x=2 and y=2

\frac{y}{x} =\frac{2}{2} =1

Since, the values of constant k is not equal for all the values of x and y in the table, this relationship is not a direct variation.

Thus, Option A is the relationship which shows direct variation.

o-na [289]
Perimeter of a rectangle= 2(length)+2(width)

Data:
Perimeter=108 cm
length=18 cm

therefore:
108 cm=2(18 cm)+2(width)
108 cm=36 cm+2 (width)
2 width=108 cm -36 cm=
2 width=72 cm
width=72cm/2
width=36 cm

Answer: the width of the picture frame would be 36 cm.
