Tatiana [17]

Answer:The quotient of -100 and -5  is the same as the quotient of 100/5 because if you divide a negative number by a negative number, you will get a positive number and the same way if you divide a positive number by a positive number you will get a positive number.

Help me please help. ​
Ray Of Light [21]

Answer:

steps below

Step-by-step explanation:

This is a contradictory proof of sophistry

f(x+4) = f(x)+f(4)  ...(1)     when x=0

f(x+4) = f(0+4) = f(4) = f(x) + f(4)

f(x) = f(4)-f(4) = 0

From (1): f(x) = f(x+4) - f(4)

x=-4      <u> f(-4)</u> = f(-4+4) - f(4) = f(0) - f(4) = <u>-f(4)</u>   ...(2)

From (1): f(x+4) = f(x)+f(4)

x=4         f(4+4) = <u>f(8)</u> = f(4) + f(4) = 2f(4) = <u>-2f(-4)</u>   from (2) ... (3)

f(8) +2f(-4) = -2f(-4) + 2f(-4) = 0
