Your answer is 26,453
Although I don't feel as if this is a homework question, I will still show the work.
Work:
Step 1: 999 + 999 = 1,998
Step 2: 1,998 + 999 = 2,997
Step 3: 2,997 + 23,456 = 26,453
Hope I was able to help! :)
Answer:
Since, the given solution is (2, 14). Therefore, 7x−y=0. Similarly, another equation can be−x+y=−2+14=12. Similarly, another equation can be−2x−y=−2(2)−14=18.
Answer: The first blank would be 71 and the second blank would be 32 and the 3rd blank would be 8
Step-by-step explanation: because on the first on it added by 7 so you would have to do the same for all of them.
Converting to vertex form is actually pretty simple so I think you might find something to help you out here. :)
