Given that abc is congruent to def, ac=21x-19 and df=3x+17 solve for x

If 25% of y is 30, what is 60% of y?

(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 number of fish in a lake can be modeled by the exponential regression equation y=14.08 x 2.08^x where x represents the year
