I’m assuming the numbers are 2/3 and 3/4 so find the common denominator. 2/3x4=8/12 and 3/4x3=9/12 so 8/12+9/12= 17/12 or 1 and 5/12

Let V=ℝ2 and let H be the subset of V of all points on the line 4x+3y=12. Is H a subspace of the vector space V?

sergejj [24]

Answer:

No, it isn't.

Step-by-step explanation:

We have $V=IR^{2}$ and let $H$ be the subset of $V$ of all points on the line

$4x+3y=12$

We need to find if $H$ is a subspace of the vector space $V$ .

In $IR^{2}$ all the possibilities for own subspace of the vector space $IR^{2}$ are :

$IR^{2}$ itself.

The vector $0_{IR^{2}}=\left[\begin{array}{c}0&0\end{array}\right]$

All lines in $IR^{2}$ that passes through the origin ( $0_{IR^{2}}=\left[\begin{array}{c}0&0\end{array}\right]$ )

We know that $H$ is the subset of $IR^{2}$ of all points on the line $4x+3y=12$

If we look at the equation, the point $\left[\begin{array}{c}0&0\end{array}\right]$ doesn't verify it because :

$4x+3y=12\\4(0)+3(0)=12\\0=12$

Which is an absurd. Therefore, $H$ doesn't contain the origin (and $H$ is a line in $IR^{2}$ ). Finally, it can't be a vector space of $V=IR^{2}$

How many seconds are in 76 minutes

Kipish [7]

Answer:

4560

Step-by-step explanation:

Well, first we need to understand how different time formats (for lack of a better word) are related in terms of seconds.

1 minute has 60 seconds

I hour has 3600 seconds

1 day has 86400 seconds

1 week has 604800 seconds

Now, with this information at hand, you can find out how many seconds are in X minutes or X days or X months or a year (and so on).

As for your question, we know that one minute has 60 seconds therefore 76 minutes will have (76x60) seconds

Answer:

24.8 lbs

Step-by-step explanation:

14.5% is 0.145 in decimal and then you multiply it by the weight, and get the answer
