Solving special systems.

Given:

The equations of system of equations are

To find:

The solution of given system of equations.

Solution:

We have,

        ...(i)

        ...(ii)

Adding y on both sides in (ii), we get

It is same as equation (i). So, we can say that equation (i) and (ii) represent the same line or they are coincident.

Thus, the system of equations has infinitely many solutions.

Therefore, the correct option is C.

a

step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
