Answer:
D. N(a) = (a + 20)/3
Step-by-step explanation:
A(n) = 3n - 20
A is a function of n. The inverse will be: N is a function of a.
Change A(n) to y and n to x.
y = 3x - 20
Switch x and y.
x = 3y - 20
Solve for y.
x + 20 = 3y
3y = x + 20
y = (x + 20)/3
Now switch y to N(a) and x to a.
Answer: N(a) = (a + 20)/3

Answer:
JNL,JKL,KNR are three non-collinear points
Probability of an event= number of ways an event can occur / total number of possible outcomes.
Probability = 6/12 = 0.5
They are opposite side interior angles and they are exactly the same degree
