Use Pascal's Triangle
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
1 6 15 20 15 6 1
1 7 21 35 35 21 7 1
1 8 28 56 70 56 28 8 1
1 9 36 84 126 126 84 36 9 1 (this is the row you use)
So, the seventh term of (3x + 2y)^9 will be 84xy
1. 14/3
2. 9
4. 5
5. 15
(Sixth one is confusing sorry! But I hope you do well on it since I can't help you :|)
y= -4x and 8x-y=6
what you do is switch the negative y to the other side and move the positive 6 to the other side thus making y=8x-6.
I don't get what those numbers are on the question but the way you solve it is by combining them and putting one y into the other
8x-6=-4x 12x=6 6/12=x .5=x
then you plug in x to find y in whichever equation:
-4x=y -4(.5)=y -2=y
so the final answer would be (.5,-2)
