2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)

9.75 is the FINAL answer
8 students traveled in cars, which means that 450 students traveled by bus.
Since there were 10 buses, just divide the number of students by the number of buses.
450 / 10 = 45
There were B. 45 students on each bus.
(1) [6pts] Let R be the relation {(0, 1), (1, 1), (1, 2), (2, 0), (2, 2), (3, 0)} defined on the set {0, 1, 2, 3}. Find the foll

Answer:
Following are the solution to the given points:
Step-by-step explanation:
In point 1:
The Reflexive closure:
Relationship R reflexive closure becomes achieved with both the addition(a,a) to R Therefore, (a,a) is 
Thus, the reflexive closure: 
In point 2:
The Symmetric closure:
R relation symmetrically closes by adding(b,a) to R for each (a,b) of R Therefore, here (b,a) is:

Thus, the Symmetrical closure:

X = -1.8 * 2.1
x = 3.78
