Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
y = 7x - 8 → (1)
y = 5x - 2 → (2)
A
Solving by substitution
Substitute y = 7x - 8 into (1)
7x - 8 = 5x - 2 ( subtract 5x from both sides )
2x - 8 = - 2 ( add 8 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Substitute x = 3 into either of the 2 equations and evaluate for y
Substituting into (1)
y = 7(3) - 8 = 21 - 8 = 13
Solution is (3, 13 )
B
The point of intersection of the graph of the 2 equations is the solution to the above equations.
That is point of intersection = (3, 13 )
Answer:
the Prime Factors of 12 are: 2, 2, 3.
Step-by-step explanation:
Therefore 12 = 2 X 2 X 3.

Answer:
C) 67%
Step-by-step explanation:
Conditional probability:
P(A given B) = P(A and B) / P(B)
P(passed 2nd given passed 1st) = P(passed 2nd and 1st) / P(passed 1st)
P(passed 2nd given passed 1st) = 0.30 / 0.45
P(passed 2nd given passed 1st) = 0.67
