Answer:
Step-by-step explanation:
2
2 minus signs multiplied together give a plus. The number line I'm using does not have any y values.
Answer:
-2
Step-by-step explanation:
Answer:
inf(A) does not exist.
Step-by-step explanation:
As per the question:
We need to prove that A is closed under multiplication,
If for every
Proof:
Suppose, x, y
Since, both x and y are real numbers thus xy is also a real number.
Now, consider another set B such that:
B = {xy} has only a single element 'xy' and thus [B] is bounded.
Since, [A] represents the union of all the bounded sets, therefore,
⇒ xy
Therefore, from x, y , we have xy .
Hence, set a is closed under multiplication.
Now, to prove whether inf(A) exist or not
Proof:
Let us assume that inf(A) exist and inf(A) =
Thus is also a real number.
Let C be another set such that
C = { - 1}
Now, we know that C is a bounded set thus { - 1} is also an element of A
Also, we know:
inf(A) =
Therefore,
But
is an element of A and
This is contradictory, thus inf(A) does not exist.
Hence, proved.
B) $10.00
C) $25.20
D) $5.20
Answer:
k=4/3
Step-by-step explanation:
5(2k-1)-k=7
10k-5-k=7
9k=12
k=4/3
The terms of an expression 4x² – 3xy are:
(a) 4x and -3xy (b) 4x² and 3xy
(c) 4x² and -xy
(d) x
Answer:
(b) 4x² and 3xy
Step-by-step explanation:
The terms of an expression 4x² – 3xy are:
The terms are the factors of the expression, which are 4x² and -3xy. The signal is not counted as a term. So the correct answer is given by option b.
