The U and inverted U symbols, ∪ and ∩, are mathematical symbols used to denote union or intersection, respectively. For example, when a rational algebraic equation is graphed, there may be some points where the equation is undefined. Visually, we see it as breaks or discontinuities. We use the ∪ symbol to express union. For example, {-∞,2)∪(4,+∞). That means that the graph passes at all x values except x=3.
The ∩ symbol is used for intersection of two lines, for instance. When equation A and equation B are graphed, they can intersect at points (x,y). It is therefore expressed as: A∩B = (x,y).
D) 1\9 because it has zero X
B) 5
A) the difference is that 1/9 has zero X and 4\9 and 5\9 have the highest which is 4
B) 4
Answer:
the unit of the rate is 3.5cm since, the rate is 8,28. The two point lies on 3.5
50 cars per hour
To calculate the hourly rate divide 400 by 8
hourly rate = 
= 50 cars per hour
