Can help me pleaseee I need help

Use set builder notation to represent the following set: { -3, -2, -1, 0}

What is the solution of the systems of equations? y=2/3x+3 x=-2

(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
