(1 point) 9. A student mixed two clear liquids together in a beaker. A solid and a new liquid
formed. The student forgot to write down the mass of one of the reactants. The rest of
the data are shown in the table below.
liquid reactant A
liquid reactant B
liquid product
solid product
Mass (g)
unknown
9.0
8.0
12.0
What is the mass of liquid reactant A?
O 1.0 g
08.0 g
09.0g
O 11.0 g
O 20.0 g

Can’t seem to figure this one out

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
