Im so bored so wassuh :/

Which value of m will create a system of parallel lines with no solution? y= mx - 6 8x - 4y = 12

Atransformation t : (x,y) (x-5,y +3) the image of a(2,-1) is

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
