Step-by-step explanation:
B. The equality relation on the real numbers is an equivalence relation.
This statement is true
C. If RR is a reflexive relation on a set S, then any two RR- related elements of S must also be R2R2 related.
This statement is true
F. The less than or equal relation on the real numbers fails to be an equivalence relation because it is reflexive and transitive but not symmetric
This statement is true
H. If RR is an equivalence relation, then R2
This statement is true
Answer:
10 miles if im not wrong
Step-by-step explanation:
Answer:
D=24
Step-by-step explanation:
y inversely as x
x=k/y
By cross multiplication
k=xy
k=12*6
k=72
finding y
72=3y
y=24
Answer:
Upper left corner
Step-by-step explanation:
Divide the distance D over the time T. If you travel D = 325 miles for T = 5 hours, then your speed or rate R is
R = D/T = 325/5 = 65
So you're traveling at 65 miles an hour if you travel 325 miles in 5 hours, which is what the upper left corner diagram is showing.
2x squared +1 (-)x squared -7 is
a.) x squared +8
