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)

Step-by-step explanation:
It equals 3.
Answer:
9.2
Step-by-step explanation:
Since it is a right triangle, we can use pythagorean theorem to figure out the hypotenuse length.
a^2 + b^2 = c^2
6^2 + 7^2 = c^2
36 + 49 = c^2
c^2 = 85
square root both sides get
c= 9.219, rounded to nearest tenth is 9.2

The answer would be 36 because theres 6 people and 6 seats so 6*6 = 36
