Which table will have the greatest value of y when x = 7?

Answer: The answer is the third table.
Step-by-step explanation: We are to check for which of the given four tables, the value of y at x = 7 is greatest.
For the first table, at x = 7, we have
[tex]y=2^7=128.[/tex]
For the second table, at x = 7, we have
[tex]y=14+6\times 12=14+72=86.[/tex]
For the third table, at x = 7, we have
[tex]y=7\times 21=147[/tex]
For the fourth table, at x = 7, we have
[tex]y=12+6\times 10=12+60=72.[/tex]
Since 147 is the greatest of all the four values, so the third table will be the correct option.
Thus, the answer is the third table.
