Answer:
D. (4, -6)
Step-by-step explanation:
Since the heights of both triangles are the same (CD), their areas are proportional to their bases. That is ...
AC : CB = 3 : 4
In terms of coordinates, ...
4(C -A) = 3(B -C) . . . . multiply the ratios by 4(CB)
4C -4A = 3B -3C . . . .simplify
7C = 4A +3B . . . . . . . isolate C
C = (4A +3B)/7 . . . . . divide by 7
C = (4(1, -9) +3(8, -2))/7 = (28, -42)/7 . . . . substitute given coordinates
C = (4, -6)
Well, you would use factorization for this, which would be MORE than 54 different codes! :D
First you have to find out the cost for a single egg.
Since there are a dozen (12) eggs, you can divide the total cost by that.
1.12/12 ≈ 0.09.
Using the base cost of an egg, you can find out how much 3 eggs would cost.
0.09 x 3 = $0.27
Answer:
x= 5/2 + y/2
Step-by-step explanation:
So yeah... that's the answer
