Answer:
A.
Step-by-step explanation:
Because I used the Internet.
:)
If the smaller number is x, then the larger number has to be 20 - x in order for the arithmetic mean to be 10, as their sum must be 20.
If the geometric mean is 8 the product of the numbers has to be 64 and so the larger number is 64/x
Solving 64/x = 20 - x gives the quadratic x^2 -20x +64 = 0 so x = 4 or 16.
The two numbers are 4 and 16.
Let us break it down. A sum of ten. That is just
+10
Then, we will add that to the quotient (which is the number after dividing) of a number x and 6. We can write that as
+ x/6
The slash means division here. Thus your final answer is
10 + x/6
Ie 32^2 - 4ac=0 so ac=256 and a+c=130
So, that means:2 equations ac=256 a+c=130 ie c=130-a
So,a(130-a)=256 so 130a -a^2=256 ie a^2-130a +256=0 (a-2)(a-128)=0
Finally,giving a= 2 or a=128 so, a=2 c=128 or a=128 c=2
Since, a>c , a=128 and c=2 ie (128,2)
Answer: I believe this is a reflection
Step-by-step explanation: I think this is a reflection because the points are flipping to the exact opposite y coordinate.
Hope this helps.
