What are the coordinates of the image of vertex f after a reflection across the line y= -x

B.

Step-by-step explanation:

We have been given an image of a quadrilateral. We are asked to find the coordinates of the image of vertex F after a reflection across the line .    

We know that rule of reflection across the line is .

We can see that coordinates of point F are .

After reflecting point F across the line , the x- and y-coordinates will interchange their place and their signs will be changed as well.

Therefore, the coordinates of the image of vertex F after a reflection across the line are and option B is the correct choice.

can someone answer this question plz

step-by-step explanation:

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
