Step-by-step explanation:
Permutations are involved when order matters, as in lane assignment, passwords, and seating charts.
When the end result is a "group of 10 students", "3 employees", or "4 cashiers", clearly order does not matter. One student, employee, or cashier is as good as another in these cases.
Answer:
f(x)= -54x -4
g(x)= -3x -2
f+g)( x)= -54x -4 -3x -2 = -57x -6
Answer:
Step-by-step explanation:stupid
To solve the question, the both equations should have a positive value and a negative value with same number. Then one variable can be eliminated.
To eliminate X term first, we should multiply the first equation by 2 and second one by 3.
Then,
6X - 12Y = -30
-6X + 15Y = 70
Or
To eliminate Y term first, we should multiply the first equation by 5 and second one by 6.
Then,
15X - 30Y = -75
-12X + 30Y = 84
According to the choices given 'A' is the correct answer.
