Suppose that the total profit in hundreds of dollars from selling x items is given by P(x) =4x2 - 5x + 10. Find the marginal profit at x=5

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:

i believe the correct answer is b.

i believe the answer is c.

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
