Abottlenose dophin is 10 ft below sea leval then it begins to dive at a rate of 9ft per second what is the equation of the line that represents its elevation y after x seconds

With: label the vertices and all the elements needed. find x

Explain how you do each step what term makes it inconsistent y=2x - 4 ?

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
