Question

-8+8xy , при х= o,y = -1

Answer 1

-8 + 8 (0•(-1)) = -8 + 8 • 0 = -8

Answer 2

To evaluate the expression -8 + 8xy when x = 0 and y = -1, we substitute these values into the expression and perform the calculations:

-8 + 8xy = -8 + 8(0)(-1)

Since x = 0 and y = -1, we can simplify further:

-8 + 8(0)(-1) = -8 + 0 = -8

Therefore, when x = 0 and y = -1, the value of the expression -8 + 8xy is -8.
