Write two linear functions, (x) and g(x). for example, f(x) = 3x - 7 and
g(x) = -2x + 5. then see whether rx) - (-9(x)) is equivalent to f(x)+ g(x). hint:
to find -9(x), just change the signs of all the terms in g(x). discuss whether
you think your results would apply to every function.

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
