Is (-5,-5) a solution of y \geq -2x +4y≥−2x+4 ?

What is the missing constant term in the perfect square that starts with x^2 -20x

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3

Which shows the correct substitution of the values a, b and c from the equation 1=-2x+3x^2+1
