How do you determine the solution to a system of linear equations when graphed?

(mc 02.03) what set of reflections and rotations would carry rectangle abcd onto itself? reflect over the y-axis, reflect over the x-axis, rotate 180° rotate 180°, reflect over the x-axis, reflect over the line y=x reflect over the x-axis, rotate 180°, reflect over the x-axis rotate 180, reflect over the y-axis, reflect over the line y=x

The square root of 9x plus 7 plus the square rot of 2x equall to 7

If f(x)=x+7 and g(x)=1/x what is (fog)(x)
