In a function, y varies inversely with x. The consistent of variation is 4. Which table could represent the function?

lianna [129]

Answer:

none of the tables shown

Step-by-step explanation:

Inverse variation is

xy = k where k is the constant

xy = 4

in the top table

-2*2 = -4 so it cannot be the first table

In the middle table

-2 * -8 = 16 so it is not the middle table

In the bottom table

-2 *4 = -8 so it is not the bottom table

There must be a table not shown

The length of a rectangle is 2 m longer than its width. if the perimeter of the rectangle is 40 m , find its area.

vredina [299]

L=w+2 and 2w+2l=40

Substitute length for w+2 in perimeter formula.

2w+2(w+2)=40
2w+2w+4=40
4w+4=40
4w=36
w=9

l=w+2
l=9+2
l=11

a=lw=11*9=99 meters
