jeremy says that the expression -3 + 5 + 8(-4 x -2) simplifies to a negtive number because if you multiply three negative numbers the final anwer will be negative is he correct? explain why or why not
(This question is asking if Jeremy's logic of counting negatives to decide if an answer is negative, in this type of specific problem, is correct thinking. You do not need to work out the problem to see if you get a negative. You want to think about his logic in determining if he believes this should be a negative.)
You can settle your argument by going through this step by step:
Solve for x:
-2 (16 x+7) = 0
Divide both sides by a constant to simplify the equation.
Divide both sides of -2 (16 x+7) = 0 by -2:
(-2 (16 x+7))/(-2) = 0/(-2)
Any nonzero number divided by itself is one.
(-2)/(-2) = 1:
16 x+7 = 0/(-2)
Any number times zero is zero.
0/(-2) = 0:
Answer: |
| 16x+7 = 0
