Answer:
<h2>y = 3</h2>
Step-by-step explanation:
If a line has slope 0, then it's a horizontal line.
A horizontal line has an equation:
<h2>y = a</h2>
where a is any real number.
The line passes through point (-12, 3) → x = -12, y = 3.
Therefore the equation is
<h2>y = 3</h2>
3a + 6b = 45
2a - 2b = -12....multiply by 3
----------------
3a + 6b = 45
6a - 6b = - 36 ...(result of multiplying by 3)
---------------add
9a = 9
a = 1
3a + 6b = 45
3(1) + 6b = 45
3 + 6b = 45
6b = 45 - 3
6b = 42
b = 7
solution is : (1,7)

Answer:
7/80
Step-by-step explanation:
Given that: P(B) = 7 / 20, P(A|B)= 1 / 4
Bayes theorem is used to mathematically represent the conditional probability of an event A given B. According to Bayes theorem:
Where P(B) is the probability of event B occurring, P(A ∩ B) is the probability of event A and event B occurring and P(A|B) is the probability of event A occurring given event B.
