The point (7,8) in the coordinate plane represents a ratio. Adela claims that you can find equivalent ratio by adding the same number to both coordinate of the point. is Adela correct? Explain.

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

Which inequality statement describes the two numbers on a number line? "? 7 and a number 5 units to the right of ? 7"

Can someone answer this question for me
