What are the similarities between the graphing method and the elimination method? What are the similarities between graphing method and the substitution method? Somebody, please help me I would appreciate it. Thank you

The function g(x) is defined as shown. x-1, -2 g(x) = 2x+3, -1 6-x, x23

The system of equations graphed below has how many solutions? y = 2x + 2

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
