Answer:its 12
Step-by-step explanation:
because there are 36 now and they have 3 times more each year so it is 12 + 12 + 12 = 36
I thought it was eight bro;;-;
The slope is the change in Y over the change in X
The change in y is -2-0 = -2
The change in X is 3-9 = -6
The slope is -2/-6, which simplifies to 1/3
3x-4 is the answer, you have to see that if its 3 times her nieces age it would be 3x and if its four less than that it is 3x-4
