Answer:
there are no solutions
Step-by-step explanation:
Answer:
y ≤
Step-by-step explanation:
We are to put the linear inequality;
7x - 4y ≥ 20
in slope intercept form.
We can rearrange the inequality as;
-4y ≥ - 7x + 20
Dividing throughout by -4 we get;
y ≤ - 5
Note that the inequality sign '≥' changes to '≤' since we divided all through with a negative number.
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:
$166.42.
Step-by-step explanation:
We have been given that the price of the cell phone is expected to increase by 165% in September 2015. The current price of a cell phone is $62.80.
The price of cell phone in September 2015 will be $62.80 plus 165% of $62.80.
Therefore, the predicted cost of a cell phone in September 2015 will be $166.42.
