Q. Which of the following is a correct interpretation of the expression 2(7)? 2-(-7) ? \newlineChoose 11 answer:\newline(A) Start at 22 on the number line and move 77 to the left\newline(B) Start at 22 on the number line and move 77 to the right\newline(C) Start at 7-7 on the number line and move 22 to the left\newline(D) Start at 7-7 on the number line and move 22 to the right
  1. Simplify the expression: Let's first simplify the expression 2(7)2-(-7).\newlineSubtracting a negative is the same as adding the positive equivalent of that number.\newlineSo, 2(7)2-(-7) becomes 2+72+7.\newlineNow, let's add the numbers.\newline2+7=92 + 7 = 9
  2. Subtracting a negative: Now that we have simplified the expression to 99, let's interpret the original expression in the context of a number line.\newlineThe expression 2(7)2-(-7) effectively means starting at 22 and adding 77, because subtracting a negative number is the same as adding its positive counterpart.\newlineOn a number line, adding 77 to 22 means moving 77 units to the right from the starting point of 22.
