Which transformations could have been performed on triangle jkl to form congruent triangle j ' k ' l '?
choose exactly two answers that are correct.

a.
triangle jkl was rotated 90° counterclockwise around the origin to form triangle jꞌkꞌlꞌ.

b.
triangle jkl was rotated 90° clockwise around point p to form triangle jꞌkꞌlꞌ.

c.
triangle jꞌkꞌlꞌ was reflected across the line x = minus 4 to form triangle jꞌꞌkꞌꞌlꞌꞌ.

d.
triangle jꞌkꞌlꞌ was reflected across the x-axis to form triangle jꞌꞌkꞌꞌlꞌꞌ.

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

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.
