Answer:

Math is considered to be a part in everyones life, for example, you use math to throw a ball, like the force you use, or the height of the ball. Math is an important concept, and is lingering in our everyday lives, but the reason we take math is to find out of its exsitence, and use it for engineering, etc.

Frank has 8 soup bowls. He wants to pour 1/3 pint of soup in each bowl. Will Frank need more or less than 8 pints? How much soup

Margarita [4]

He would need less than 8. So he would need 2.5 pints. I think.

Answer:

4 over 9

Step-by-step explanation:

4 over 7 = 0.571428571

2 over 5 = 0.4

7 over 8 = 0.875

Find the augmented matrix for each of the following systems of linear equations. (a) x₂ - 2x2 = 0 (6) x + x₃ = 1 .3x₂ + 4x2 = -1

Y_Kistochka [10]

Answer:

The augmented matrix for each set of linear equations is:

a) $x_1-2x_2=0\\3x_1+4x_2=-1\\2x_1-x_2=3$

Augmented matrix:

$\left[\begin{array}{ccc}1&-2&0\\3&4&-1\\2&-1&3\end{array}\right]$

b) $x_1+x_3=1\\-x_1+2x_2-x_3=3$

Augmented matrix:

$\left[\begin{array}{cccc}1&0&1&1\\-1&2&-1&3\end{array}\right]$

c) $x_1+x_3=1\\2x_2-x_3+x_5=2\\2x_3+x_4=3$

Augmented matrix:

$\left[\begin{array}{cccccc}1&0&1&0&0&1\\0&2&-1&0&1&2\\0&0&2&1&0&3\end{array}\right]$

d) $x_1=1\\x_2=2$

Augmented matrix:

$\left[\begin{array}{ccc}1&0&1\\0&1&2\end{array}\right]$

Step-by-step explanation:

In order to find the augmented matrix, you have to take the numeric values of each variable and make a matrix with them. For example, in the linear system a) you can make a matrix out of the numeric values accompanying x_1 and x_2, this matrix will be:

$\left[\begin{array}{cc}1&-2\\3&4\\2&-1\end{array}\right]$

Then you have to make a vector with the constants in the linear equations, for the case of system a) the vector will be:

$\left[\begin{array}{c}0&-1&3\end{array}\right]$

To construct the augmented matrix, you append those matrices together and create a new one:

$\left[\begin{array}{ccc}1&-2&0\\3&4&-1\\2&-1&3\end{array}\right]$
