Trapezoid jklm has points j(-2,-4), k(2,-4), l(4,2), and m(-4,2) which transformation will map the trapezoid to itself? reflection across the x-axis reflection across the y-axis rotation of 90 degrees about the origin rotation of 180 degrees about the origin

(B)

Step-by-step explanation:

JKLM is a trapezoid with points  J(-2,-4), K(2,-4), L(4,2), and M(-4,2) plotted on XY-Plane.

By mapping, we mean that that the figure obtained after the translation is same as the original one.

The transformation which will map the trapezoid itself will be the reflection across y-axis.

Hence, option (B) is correct.

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.

The answer is d, none of above hope i
