In 16years, ben will be 3 times as old as he is right now.
how old is he right now?

8 years old is he right now.

Step-by-step explanation:

Let the present age of Ben be x.

As per the statement:

After 16 years.

Age of Ben will be = x + 16

In 16 years, Ben will be 3 times as old as he is right now.

⇒

Subtract x from both sides we have;

Divide both sides by 2 we have;

8 = x

or

x = 8 years

Therefore, 8 years old is he right now.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
