C. only line u and line v
(2x+23)+(9x-5)=95
11x+18=95
x= 95-18/11
x=7
therefore substituting value of x in the given equations of angles:
angle ABD = 2(7)+23=37°
angle DBC = 9(7)-5= 58° Answer
to verify = 37°+58°= 95° ( which was given)

D) same sex
2/8=1/4
Answer:
Step-by-step explanation:
Given that:
A country population at any given time (t) is:
where;
P = population at any time t
k = positive constant
I = constant rate of immigration into the country.
Using the method of separation of the variable;
Taking integration on both sides:
By applying the exponential on both sides;
Assume
Then:
When time t = 0, The Total population of the country is also
C - I = kP₀
C = kP₀ + I
Substituting the value of C back into equation(1), we have:
