What is the solution to (x - 5)(2x + 1)(x – 7) > 0? 0 (-0.5, 5) U (7,00)
0 (-0, -0.5) U (5, 7)
0 (-0.5, 5] U [7,00)
0 (-00, -0.5] U [5, 7]

-1/2 < x < 5  or x>7

Step-by-step explanation:

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
