Quadrilateral ABCD has coordinates A(-4, -2), B(-3, 1), C(0, 1), and D(1, -4). Find the coordinates of Dʹ, the image of D, after a reflection over the y-axis.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
