I'm trying to solve a rational equation and i don't know what exactly to do with the 2x^2. here's what i have so far: (x) / (x+2) + (x) = (5x+8) / (x+2) (x+2)(x) + (x+2)(x) = (5x+8) (2x^2) + 4x = (5x+8) - 4x = -4x 2x^2 = x+8 0 = 2x^2 + x+8 then how do i factor this to find my x's

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

graph of this function as shown below:

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
