Question

Which equation represents the following table?

Answer 1

Answer:

$y=19.5x+30$

Step-by-step explanation:

there are 4 equation

1)  $y =19.5x+30$

2) $y=30\times 19.5^x$

3) $y = 19.5\times30^x$

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) $1) \ y= 19.5\times0+30=30\\2)\ y=(30\times19.5)^0=1\\3)\ y=(19.5\times30)^0=1\\4)\ y=30\times0+19.5=19.5$

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