Answer:
This statement is "TRUE".
Step-by-step explanation:
Every elementary row operation is reversible. You can get the reverse answer by multiplying by a constant or by multiplying by its inverse. You can add one row to another row and subtract row 1 from row 2 to get it back.
The polynomial y3 - 11xy2 + 2x2y - 13x3 corresponds to the subtraction
of multivariate polynomial because of the minus and plus sign in it. Also, the
variables cannot be easily added or subtracted because they are all different. Unlike
in the polynomial 19x3 + 44x2y + 17, it has no minus sign.
Well, to get this, you would have to multiply 7.8 by 2 or add 7.8 to 7.8, the reason you would have to do this is because the midpoint is 1/2 of the line. So 7.8+7.8=15.6.
15.6 (D) is your answer.
Hope this helped!
