The answer is: 10
Hope this helps! (:
Answer:
Step-by-step explanation:
use formula
F = 1/2*sqrt[ 4* r^2 -CD^2 ]
F = 4.4721
Armans age : x
Aregs age: y
X = 5y
(15 - 12) = y. They said narek is 12 years older than areg so you deduct 12 years from nareks age which is 15.
So therefore y = 3. So Areg is 3 years old.
Since we know that y = 3
X = 5(3)
X = 15
So therefore Arman is 15 years and Areg is 3 years.
The answer is “No” because the line is not proportional.
Given inequality is:

Now for (6,-4), Put x=6 nd y=-4 in given inequality:

So for (6,-4) this inequality is true.
For (-2,-3) put x=-2 and y=-3 in given inequality:

As -32 is less than -8 then this condition is also true.
simillarly you can check for other options also.
For (-7,5) Put x=-7 and y=5 in given inequality:

As 12 is grater than -8 so this condition is false.
And for (-6,0) put x=-6 and y=0 in given inequality:

As -24 is less than -8 so it is true.
