The answer is 0.45

------------------------------------

Work Shown:

P(B|A) = P(B and A)/P(A)
0.2 = P(B and A)/0.9
0.2*0.9 = P(B and A)
0.18 = P(B and A)
P(B and A) = 0.18
P(A and B) = 0.18

P(A|B) = P(A and B)/P(B)
P(A|B) = 0.18/0.4
P(A|B) = 0.45

Which statement about the ordered pairs (-9, 3) and (2, - 4) is true for the equation

dybincka [34]

Answer:

(2, - 4) is a solution to the equation

Step-by-step explanation:

Substitute the x and y coordinates of the points into the left side of the equation and if equal to the right side then they are a solution.

(- 9, 3 )

6(- 9) - $\frac{3}{2}$

= - 54 - 1.5 = - 55.5 ≠ 14 ← not a solution

(2, - 4)

6(2) - $\frac{-4}{2}$

= 12 + 2 = 14 ← This is a solution

Thus (2, - 4) is a solution to the equation
