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)
<span>9x+5=4(x+2)+5x
Then distribute on the right side
9x+5=4x+8+5x
Then simplfy
9x+5=9x+8
Then subtract 9x from both sides
5=8
5 is not equal to 8 so, no answer.

When finding the square root of any number there is is the + and - root
when using this information to solve a problem only the positive root is used
you can't solve involving measurements using the - root
hope this helps
