Please help! What set of reflections and rotations would carry rectangle ABCD into itself?

1) Rotate 180°, reflect over the x-axis, reflect over the line y=x

2) Reflect over the y-axis, reflect over the x-axis, rotate 180°

3) Rotate 180°, reflect over the y-axis, reflect over the line y=x

4) Reflect over the x-axis, rotate 180°, reflect over the x-axis

If f(x)=x^3 and g(x)=2x+7 when g(x)=-5

Worth 100 points need the answers asap first row -x^2 2x^2 (x/2)^2 x^2 x is less than 2 x is greater than 2 x is less than or equal to 2 x is greater than or equal to 2 second row -5 -5/2 4 5 •2 is less than x& x is less than 4 •2 is less than or equal to x & x is less than or equal to 4 •2 is less than or equal to x& x is less than 4 •2 is less than x& x is less than or equal to 4

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
