Answer:

The product is:

\left[\begin{array}{cc}15 & 14\\-1 & 9\end{array}\right]

Step-by-step explanation:

For this problem you need to multiply the first row only for the two first column of the others matrix and get the desired result:

\left[\begin{array}{ccc}1&3&1\\-2&1&0\end{array}\right] \times \left[\begin{array}{cc}2&-2\\3&5\\4&1\end{array}\right]

1 \times 2 + 3 \times 3 + 1 \times -2 = 15

So the value of the element in the position a_{11} is 15

1 \times -2 + 3 \times 5 + 1 \times 1 = 14

So the value of the element in the position a_{12} is 14

Then with these two values you can determinate the result matrix.

\left[\begin{array}{cc}15 & 14\\-1 & 9\end{array}\right]

Solve by elimination: 3y-4x=29<br> 2y+5=4
Vaselesa [24]

The solution is x = -61/8 and y = -1/2.

<u>Step-by-step explanation</u>:

The given equations are -4x + 3y = 29 and 2y + 5 = 4

   <u>Step 1</u> : There is no x term in the second equation.

   <u>Step 2</u> : Solve for y, 2y = 4 -5

                                      y = -1/2

   <u>Step 3</u> : Substitute y = -1/2 in first equation and solve for x.

   <u>Step 4</u> : -4x + 3(-1/2) = 29

                 -4x -(3/2) = 29

                 -8x -3 = 29\times2

                 -8x = 58 + 3

                  x = -61/8

lozanna [386]
One of the bottles has a greater total volume than the other. for example, if one bottle is 20 ounces and the other is 100 ounces, when the 100 ounce bottle is 3/4 full there are 75 ounces of fluid inside which is more than the total amount of fluid in the full 20 ounce bottle.
