Simplify: 3x - 9 + 13x - 6 solve this for me! it's probably easy for a lot of people, but i struggle big time with geometry. u!

You can sum like terms. Two terms can be summed if they are both constants (i.e. pure numbers) or if they involve the same powers of the same variable.

In this case, 3x and 13x can be summed because they both involve 'x' alone. The sum is

As for the other two terms, you simply have to sum two numbers, as usual:

So, the final answer is

  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.

no he doesnt because "-16' is negatiive
