Question is in picture.

. i need fast. will mark brainliest!
i also have another question on the same topic, so if you could with both that would be greatly appreciated!

Step-by-step explanation:

Having the system of equations in its simplest form

If

then the system of equations has infinitely many solutions.

If

then the system of equations has no solution.

If

then the system of equations has one solution.

We have the equation

Convert to the standard form Ax + By = C:

             add 2x to both sides

f(x) has value 150 at x= 0

and 0 at x= 3

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