Answer:
No, it isn't.
Step-by-step explanation:
We have [tex]V=IR^{2}[/tex] and let [tex]H[/tex] be the subset of [tex]V[/tex] of all points on the line
[tex]4x+3y=12[/tex]
We need to find if [tex]H[/tex] is a subspace of the vector space [tex]V[/tex].
In [tex]IR^{2}[/tex] all the possibilities for own subspace of the vector space [tex]IR^{2}[/tex] are :
[tex]IR^{2}[/tex] itself.The vector [tex]0_{IR^{2}}=\left[\begin{array}{c}0&0\end{array}\right][/tex]All lines in [tex]IR^{2}[/tex] that passes through the origin ( [tex]0_{IR^{2}}=\left[\begin{array}{c}0&0\end{array}\right][/tex] )We know that [tex]H[/tex] is the subset of [tex]IR^{2}[/tex] of all points on the line [tex]4x+3y=12[/tex]
If we look at the equation, the point [tex]\left[\begin{array}{c}0&0\end{array}\right][/tex] doesn't verify it because :
[tex]4x+3y=12\\4(0)+3(0)=12\\0=12[/tex]
Which is an absurd. Therefore, [tex]H[/tex] doesn't contain the origin (and [tex]H[/tex] is a line in [tex]IR^{2}[/tex]). Finally, it can't be a vector space of [tex]V=IR^{2}[/tex]

1/4 + 1/3 + 11/12 = ?
(Pls draw it out and add an image for your answer!!)
Answer:
1 1/2
Step-by-step explanation:
1/4 + 1/3 + 11/12
Multiplying the equations to have a common denominator (12).
1/4 times 3 = 3/12
1/3 times 4 = 4/12
3/12 + 4/12 + 11/12
Then add.
18/12
Then convert to mixed fraction.
1 6/12
Then simplify the fraction.
1 1/2
=1×4/4×3+1×4/3×4+11/12
=3/12+4/12+11/12
=3/2

Answer:
4 - pound bag of pears for $14.08
Step-by-step explanation:
To find out which is the better deal, we have to simplify it.
By dividing $14.08 by 4, this gives us the amount of $ each pound costs, which is $3.52.
Now let's find out the amount of $ each pound costs for the 94- ounce bag of pears for $22.56.
First, we need to convert from ounces (oz) to pounds (lbs).
There are 16 ounces in one pound, and we have 94 ounces. So, 94/16 = 5.875 pounds. So there are 5.875 lbs in the $22.56 bag. Now we need to find the amount of $ each pound costs. So we divide $22.56 by 5.875 and we get $3.84.
$3.52 < $3.84 (this is the amount of money each pound of pears cost for each bag). The first bag is cheaper per pound, so they should buy the first one (which is the 4 pound bag btw).
You start at (4, -4). You move left 4 units and right 4 units. Where do you end?
Answer:
Step-by-step explanation:
(4 , - 4) -----> ( 4 - 4 + 4 , - 4 ) = ( 4 , - 4 )

It should be the second one
Step-by-step explanation:
Because in cubic inches it is 1,000.
Ariel incorrectly says that 2 5/8 is the same as 2.58
Answer:
ariel is incorrect because 2 5/8 is equal to 2.63
Step-by-step explanation:
The correct decimal value is 2.63
We have Ariel who incorrectly said that [tex]2\frac{5}{8}[/tex] is the same as 2.58
We have Convert [tex]2\frac{5}{8}[/tex] into a decimal correctly.
How will you convert the mixed fraction - [tex]$a\frac{x}{y}[/tex] to normal fraction?The method to convert the mixed fraction to normal fraction is -
[tex]$\frac{y\times a + x}{y}[/tex]
According to question, we have -
Mixed fraction = [tex]2\frac{5}{8}[/tex] = [tex]\frac{21}{8}[/tex] = 2.625 = 2.63
Hence, the correct decimal value is 2.63

what is the value of the expression 3p (4p +5) + 3 for p= -1 is
plzzzzzzzz i want it fast
Answer:
0
Step-by-step explanation
well at least thats my guess!
we have to go by bidmas. so you substitute first!
so its going to be: 3(-1)(4(-1)+5)+3
all I did is that I replaced all p's by -1 and then you multiply it!
so its gonna be: -3(-4+5)+3
you first solve what's in the brackets which is -4+5 so the answer is 1 like this: -3(1)+3 now its much simpler. all we have to do is to expand the bracket so its going to be -3+3 so the answer is 0!

If you draw a single card once from a deck of ordinary laying cards, what is the probability that it will be a 3 or a black card
Answer:
The required probability = 0.5385
Step-by-step explanation:
The no. of cards in a deck = 52
The event of having 3 in a draw of a single card = 4/52
The event of having a black card in a draw of a single card = 26/52
The event of having a black card and 3s = 2/52
Let T represent the event of having 3.
U to represent the event of having a black card; &
V to represent the event of having a black card that is 3s
Then the probability that it will be a 3 or a black card is;
P( T or U) = p(T) + p(U) - p(T and U)
P( T or U) = 4/52 + 26/52 - 2/52
P( T or U) = (4+26-2)/52
P( T or U) = 28/52
P( T or U)= 7/13
P( T or U) = 0.5385
A scientist needs 80 liters of a 30% solution of alcohol. She has a 20% solution and a 60% solution available. How many liters of the 20% solution and how many liters of the 60% solution should she mix to make the 30% solution?
Answer:
60 liters of 20% solution & 20 liters of 60% solution
Step-by-step explanation:
80*0.3=.2x+0.6(80-x)
24=0.2x+48-0.6x
-24=0.2x-0.6x
-24=0.4x
24=0.4x
