Answer:
Uh I don't really know where the question was in that sentance, but if your trying to convert it to meters the answer is 204.521 meters.
Step-by-step explanation:
We can plug the given point in each equation and check if it satisfies it
1.
5x - 2y + 1 > 0
5(-2)-2(-1)+1>0
-10+2+1>0
-7>0 (false)
2.
-5x + 2y + 1 > 0
-5(-2) + 2(-1) + 1 > 0
10-2+1>0
9>0
so -5x + 2y + 1 > 0 satisfies the given point (-2,-1)
This one is for number 26
Answer:
1
Step-by-step explanation:
Let us consider the case of 3 numbers: x, y, and z.
Then x/x+y+z + y/x+y+z + z/x+y+z = x+y+z/x+y+z = 1
The same works also for any quantity of numbers.
