Question

Which equation represents the following table?

Answer 1

`y=19.5x+30`

Explanation:

there are 4 equation

1)
`y =19.5x+30`

2)
`y=30* 19.5^x`

3)
`y = 19.5*30^x\\`

4)
`y= 30x+19.5`

Let us take first data when x = 0 y will become 30

Putting the above data of x in all 4 equation and will find y to match the same.

1)
`1) \ y= 19.5*0+30=30\\2)\ y=(30*19.5)^0=1\\3)\ y=(19.5*30)^0=1\\4)\ y=30*0+19.5=19.5`

Hence from above prove we can say that equation
`y =19.5x+30` represent the table.
