8/12-9/12 multiply 4 by 3 and then multiply 3 by 3 and you'll get 9/12
Hey there! I'm happy to help!
A permutation is focused on a specific order, while a combination is not focused on the order but on the content of what is grouped.
AB and BA are different permutations because they are in different orders, but they are the same combination because they both contain the letters A and B.
So, we see that AB and BA are one combination.
AC and CA are also another combination because they are made up of the letters A and C.
Same goes for BC and CB, this is also one combinations.
This totals up to C. 3 combinations. Now you know the difference between permutations and combinations!
Have a wonderful day!
Answer:
the 3rd one
Step-by-step explanation:
Answer:
The equation of the line would be y = -4/3x - 15
Step-by-step explanation:
In order to find the equation of this line, we first have to note that perpendicular lines have opposite and reciprocal slopes. Therefore, since the original line has a slope of 3/4, we know the new line will have a slope of -4/3. Now we can use that information along with the given point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 1 = -4/3(x + 12)
y - 1 = -4/3x - 16
y = -4/3x - 15
