Since "K" is on the right side of the equation, switch the sides so it is on the left side of the equation. Simplify 5(-3k+5). Move all terms containing "K" to the left side of the equation. Move all terms not containing "K" to the right side of the equation. Divide each term by 12 and simplify. So, "K" = 2.
1) y = -f(x) (This is the reflection about the x-axis of the graph y = f(x).) That is for every point (x, y) there is a point (x, -y). Look at the example graphs below of y = x2 and y = -x2. Notice the green graph is simply the same as the blue graph folded down
