Solve the equation 2x^2+15x^2

you can only add like terms, for example; 2x + 3x = 5x as they both have an x next to the numbers.

you cannot simplify 2 + 4x as they both don’t have an x next to them.

hence why, the answer to 2x^2 + 15x^2 would be 17x^2

Step-by-step explanation:

  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.
