If ƒ(x) = 10x + 7 and g(x) = x2 - 7x, find (ƒ - g)(x).

My answer is (ƒ - g)(x) = x2 + 3x +7 (My answer)

2. Determine whether the function shown is constant, linear, quadratic, or none of these.

m(x) = -|x - 6| + 9

My estimated guess is Quadratic.

3. Solve the system. For Y = 1/7x - 4 and X = 7y + 1

Set solution (specific numbers) , No Solution, or infinite number of solutions.

I am not sure what to do on this one.

4. Solve the system. If there's no unique solution, label the system as either dependent or inconsistent.

The equations are: 2x + y + 3z = 12

x - y + 4z = 5

-4x + 4y - 4z = -20

The options are:

(4, 1, 2), Inconsistent system (no solution), (1, 4, 2) or a Dependent system (infinite number of solutions)

In general, I am extremely horrible at the Guass-Jordan method and linear functions.
