If x=n then it would have 2 solutions because it would be x^2 = c which has a positive and negative solution but idk if that is what you are asking for
I am sure but I am going with Property if equation . this is say if x =2 then 2 x y = 2y .
Answer:
x = 26, y = 19
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
= 2 ( multiply both sides by 13 )
x = 26
and
= 
, substitute values
= 
= 
( cross- multiply )
2y = 38 ( divide both sides by 2 )
y = 19
Answer: exponential decay (choice B)
The variable x in the exponent tells us that this is an exponential function. The fact that the base 1/2 = 0.5 is between 0 and 1 indicates that the value of y will decay or get smaller as x increases. Visually, it graphs out a curve that goes downhill as you read from left to right.
side note: The function f(x) = 7*(1/2)^x can be written as y = 7*(0.5)^x. It has a horizontal asymptote of y = 0 meaning that the curve will get closer and closer to the x axis, but never actually touch it.
Answer:
a) 2 people
b) 20 people
Step-by-step explanation:
a) The social network contains four people networking with six other people, altogether there are ten people netwoking together.
So, if one person in one social network, network with five others in the network, but when it is paired, we have eight altogether in the first case.
When the other case are paired, it is discovered that, the remaining pair is left with two people networking with three other people.
b) Altogether, when it is paired in each case, the following summation provides the number of people that network with each other:
First case = 1 + 5 + 2 = 8
Second case = 5 + 4 + 3 = 12
Altogether it is 20 people
