What is the final transformation in the composition of transformations that maps pre-image ghjk to image g'h"j"k"? a translation to the right a reflection across line m a 90° rotation about point g a 180° rotation about point g

a reflection across line m

step-by-step explanation:

the first transformation is a 90 degree rotation counterclockwise around the point g. this gets to image gh'j'k'. when the image gh'j'k' is reflected over the line  m the result is g'h"j"k". the final transformation is a reflection over the line  m.

an altitude of 15,000 feet

step-by-step explanation:

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
