Ascatter plot containing the point (5,9) has the regression equation y = -x-3 (see photo)

Find the equation of the trend line (line of best fit). show your work i'm using the points (34,76) (42,91)

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103

If f(x) and g(x) are inverse functions of each other, which of the following shows the graph of f(g(x)
