Solve for y. 10(30x - 5y)= -40y +600 a) y=1/3 x +6.67 b) y=3x + 595 c) y=10x +60 d) y=30x-60 I think it's d but im so dumb-

What are the domain and range of the function? f(x) = -4 (sqrt)x

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

The sum of these consecutive integers is equal to 9 less than 4 times the least of the integer. find the three integers
