1 of 41 of 4 Items Question Multiple Choice Is –7 + 9 = –9 + 7 true, false, or open? (1 point) Responses true true false false open open
false
The correct answer is "false."
To determine if the equation -7 + 9 = -9 + 7 is true, false, or open, we can solve each side of the equation separately and compare the results.
First, let's simplify the left side of the equation:
-7 + 9 = 2
Next, let's simplify the right side of the equation:
-9 + 7 = -2
Now, let's compare the results:
2 ≠ -2
Since the left side of the equation is not equal to the right side, we can conclude that the equation -7 + 9 = -9 + 7 is false.
