alexgriva [62]

Both integers have negative values

Explanation

Let

x and y represents the number

so, the options are

\begin{gathered} +\text{   +     +} \\ +\text{  +      -} \\ -\text{     +     +} \\ -\text{   +-} \end{gathered}

a) Both integers have negative values Both integers

-x-y=-(x+y)\rightarrow you\text{ will always get a negative number}

b) Both integers have positive values

x+y=+\text{  +  += you will always get a positive number}

c)One integer has a positive value, and one integer has a negative value

\begin{gathered} -x+y\text{  or x-y} \\ the\text{ sign of the result depends on the greates absolute value, it means the answer will have the same of the bigger number( absolute value)} \end{gathered}

d)The values of the two integers are opposites​

as the point C , the sign depends on the bigger number

for example

\begin{gathered} 8-5=3\text{ positive because 8 is the bigger} \\ 5-8=-3\text{ negative because (-8) is has the bigger absolute value} \end{gathered}

so, the answer is Both integers have negative values

I hope this helps you
