Me out!
the greatest integer function, shown below, is defined so that it produces the greatest integer or equal to x.
f(x)=[x]
answer and explain.
: )

less than.

Explanation:

1) The function f(x)= [x] returns the integer number that is less than x.

2) For example,

[3.0] = 3

[3.01] = 3

[3.25] = 3

[3.55] = 3

[3.99] = 3

[4.00] = 4

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
