Which expression is equivalent to 3x(bx+10−(x2−5x+c) A
(3b−1)x2−5x+10+c

B
−x2+(3b+35)x−c

C
−3bx2+25x+c

D
(3b−1)x2+35x−c

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :
