Answer:
-13/2
Step-by-step explanation:
7(y+3)=5y+8
7y+21=5y+8
7y-5y+21=8
2y+21=8
2y=8-21
2y=-13
y=-13/2
Answer:
2
Step-by-step explanation:
2/3÷1/3
Changing the divide sign into multiply will invert the term after it
So we get
(2/3)*3
(2*3)/3
We get
2

Answer with Step-by-step explanation:
Let A and B be non- empty bounded subset of R
a.We have to find why exist
If A and B are bounded set
Then there exist constant such that
and
Then , sup of A =b and sup of B=d
When a set is bounded then all elements lie in the set are lie between the constants s and t.
All elements are less than or equal to t then t is supremum of set.
Because both set are bounded and sup of both set A and B are exist.All elements A union B are less than or equal to sup A or sup B.
Then, exist.
b.We have to prove that
Suppose ,A =(1,2) and B=(2,3)
Sup A=2 , sup B=3
Upper bound of
Hence,
If A=(4,5),B=(2,3)
Sup A=5,Sup B=3
Hence,
Hence, we can say that .
Answer:
Union
Step-by-step explanation:
The <u>UNION</u> of two or more sets is the set that contains all elements of the set.
