PLZ HELP I NEED ANSWER ASAP 20 POINTS AND BRAINLIEST
michaela solved a system of linear equations that had no solution. One of the equations was x+y=5. The other equation had a y-intercept of -2. What was the other equation?

For which rational expression is -2 an excluded value of x?

If f(x) =3x-2 and g(x) =2x+1 fins (f+ g) (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
