Solve the given system using elimination. 2r + 8s = -4
7r = -6s + 8
r = −2; s = −1
r = 1; s = 2
r = 2; s = −1
r = −1; s = 2

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

Match each inequality to the number line that represents its solution

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
