What is the sum of the matrices shown below?

[7 0 -14] [-1 17 6]

Answers

Answer:

-4 26 -5

6 17 -8

Step-by-step explanation:

The matrix addition is

First row: [-4 26 -5]

Second Row: [ 6 17 -8]

What is Matrix Addition?

To add two or more matrices, the basic process is matrix addition. Matrix addition is only possible if the matrices are in the same order. By order, we mean that the matrices have the same number of rows and columns. As a result, we can add the matrices' appropriate elements. Matrix addition is not possible if the order is changed.

We will add the rows:

Addition of First row

4 + (-8) = 4- 8= -4

19 + 7 = 26

-5 + 0= -5

Addition of Second row

7 + (-1) = 7- 1= 6

0 + 17= 17

-14 + 6 = -8

When adding integers with the same sign, add the absolute values of the integers.
True or False?

Answers

Answer:

False. This only goes with integers that are both positive.

Step-by-step explanation:

For example, 7+6 is the same as |7|+|6|, which is, again, the same as 7+6.

However, when you add integers that are both negative, you're subtracting, and you'll always end up with a negative difference. Absolute values are always positive, which is why this doesn't work.

(-7)+(-6)

= -7-6

= -13

|-7|+|-6|

= 7+6

= 13

A 6-POUND BAG OF CANDY COSTS $11.28 WHAT IS THE COST PER POUND? 10​

Answers

Answer:

$1.88

Step-by-step explanation:

11.28 / 6 = 1.88

Answer: $1.88

Step-by-step explanation:

We have 6 pounds of candy that cost 11.28, and we need to find the unit rate.

If we want to find the unit rate, or the cost per pound, we can use the equation 11.28 ÷ 6.

We can then divide each side by 6, or solve the equation.

11.28 ÷ 6 = 1.88.

Therefore, the each pound of candy costs $1.88.
