Points A, B, and C are collinear. The lengths of certain segments are given. Draw a picture. Which point is between the other two?
AB = 12 km.,CB = 8 km., AC = 4 km.

What value of x is in the solution set of –5x – 15 > 10 + 20x?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

20 solve 2(4 x + 3) < 5 x + 21. a) { x | x < 9} b) { x | x > -5} c) { x | x > -9} d) { x | x < 5}
