We need to find which statement is not true:
Let us check each statement:
-They are opposite numbers.
Opposite numbers have the same distance away from zero. Hence, 7 and -7 are opposite numbers.
-They form a zero pair:
7-7 =0, the statement is true.
- They have the same absolute value
The absolute value is the not negative value no matter the sign.
Hence, l7l= 7 and l-7l= 7.
-They have a sum of -14.
Then:
7+(-7) = 0
Therefore, the last statement "They have a sum of -14" is not true.
