Answer:
Step-by-step explanation:
Much depends on how accurate an estimate you want.
If "to the nearest hundred" would be acceptable (it's a lot of work),
Round off 542817 to 542820 and 27398 to 2740. Then you'd want to subtract 2740 from 542820. (Again, it's a lot of work.)
Otherwise round off to the nearest thousand: 543000 - 27000.
Or go to the nearest ten thousand: 540,000 - 30,000 = 510,000 (estimate)
Let r be Ron's age.
let m be Mike's age.
m=r+4
m+r=84
m=84-r
r+4=84-r
2r=80
r=40
m=44
Ron is 40 and Mike is 44
So it needs to be:
64/2=32
32/2=16
16/2=8
8/2=4
4/2=2
2/2=1
So there need to be 7 rounds.
Hope this helps :)
I believe its (2,0)
because when you reflect it every positive number in the y spot will become negative, and vice versa. There is no negative or positive 0, therefore it would stay the same...
Hope I helped:)
