Penelope Downs · Answer 1

Step-by-step explanation:

The following statements are true

- The expression - (-3.5) is equivalent to 3.5. The product of 2 minus sign will give a positive sign i. e - * - = + hence - (-3.5) = (-*-) * 35 = + 35 = 35.

- The opposite of 0 is itself. There is no negative value of zero hence 0 is still the same as - 0 making the opposite of zero to still be be zero. The minus sign in - 0 is insignificant due to the insignificance of the zero digit.

- The opposite of - 3.5 is located 3.5 units to the right of 0 on the number line. Fora number line, the origin is always located at the centre. The value to the right are along the positive x-axis and are all positive values while the values located towards the left are the negative x-axis. The opposite value of - 3.5 is gotten by negating the value of - 3.5 i. e - (-3.5) to give + 3.5 and + 3.5 is a positive value which is located towards the right of a number line.

This makes the fourth statement to be False
