Answer:

| 10  -10  1  |

|  1    -2  -4 |

| -8  13 -24|

Step-by-step explanation:

First multiply each element in matrix A, this gives:

| -6  - 2  -3 |

|  1   -6   -4 |

| -4   5    0 |

Now we multiply each element in matrix B by  4, this gives:

| -16  8  -4 |

|  0   -4  0  |

|  4  -8  24 |

Finally subtract  this from the first matrix ( subtracting element by element) gives:

| 10  -10  1 |

|  1    -2  -4|

| -8   13- 24|

Write the equation of a line in slope intercept form that contains the points (0,2) and (3,4)
AlladinOne [14]

Answer:

Step-by-step explanation:

Generally equation of a line is given as

y=mx+c

Then given the point (x, y)=(0,2)

Therefore x=0 and y=2

y=mx+c

2=m×0+c

2=0+c

Then, c=2

Then intercept is 2

Also given the point (x, y)=(3,4)

x=3 and y=4 and c=2

y=mx+c

4=m×3+2

4=3m+2

4-2=3m

2=3m

Then, m=2/3

Then, the slope of the graph is 2/3

y=mx+c

Now, m=2/3 and c=2

The general equation of the line becomes

y=2/3x+2

Multiply through by 3

3y=2x+6

Then this is the equation of the line

A chess tournament starts at 12:30 p.m. and ends at 5:00 p.m. Does the tournament last more than 5 hours? Use the drop‐down menu
pychu [463]

The tournament does not last more than 5 hours because the duration of the tournament is 4.5 hours.

<h3>What is an arithmetic operation?</h3>

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We have a chess tournament starts at 12:30 p.m. and ends at 5:00 p.m.

The difference between 12:30 p.m. and 5:00 p.m. can be calculated after changing time into 24 hours clock

12:30 p.m. = 12 hours 30 minutes = 12.50

5: 00 p.m. = 17 hours 00 minutes = 17.00

Difference between them:

= 17.00 - 12.50

= 4.5 hours

4.5 < 5

Thus, the tournament does not last more than 5 hours because the duration of the tournament is 4.5 hours.

Triangle ABC was rotated about the origin. Which rule
Nuetrik [128]
<h3>Answer: Choice A   R_0, 90^{\circ}</h3>

The R stands for "rotation". The "O" as a small subscript means "origin" which is where the x and y axis cross. The 90 degrees means we rotate 90 degrees counterclockwise. This is equivalent to 270 degrees clockwise, but writing R_0, 270^{\circ} is not correct as we don't rotate 270 degrees counterclockwise.
