For the given matrix the additive inverse property is shown.

What is additive inverse of matrix?

The matrix that is created by changing the sign of each matrix element is known as the additive inverse. -(-A)=A is the notation for the additive inverse of the matrix A.

Rows and columns serve as a measure of a matrix's dimensions. Given that it has three rows and three columns, for instance, the matrix below has a dimension of 3 x 3. Three by three can be read off as the matrix's dimension. We consequently obtain the additive inverse of the matrix

M = - M.

Consider the given matrix,

[tex]\left[\begin{array}{ccc}-6&15&-2\\9&0&-3\end{array}\right] + \left[\begin{array}{ccc}6&-15&2\\-9&0&3\end{array}\right] = \left[\begin{array}{ccc}0&0&0\\0&0&0\end{array}\right][/tex]

Here each element in first matrix is negative of the element of second matrix.

That is each element is inverse of the element in second matrix.

And the addition of elements is 0.

Hence, for the given matrix the additive inverse property is shown.

The given system of equations has a solution (16/11, 24/11), so they are consistent and independent.

The given system of equations are 4x+y=8 and x+3y=8.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

Here, 4x+y=8 ----------(I) and x+3y=8 ----------(II)

Multiply equation (I) by 3, we get

12x+3y=24 ----------(III)

Now, subtract equation (II) from (III), we get

12x+3y-(x+3y)=24-8

11x=16

⇒ x=16/11

Substitute x=16/11 in equation (II), we get

16/11 +3y=8

⇒ 3y=8- 16/11

⇒ 3y=72/11

⇒ y=24/11

If equation as one solution, then they are consistent and independent.

Therefore, the given system of equations has a solution (16/11, 24/11), so they are consistent and independent.

Answer: $180

Step-by-step explanation: To calculate the total tip, you would add 10% to the bill,

Total bill = $159.67 x 1.10+ 175.637 or $175.64

$175.64 rounded to the nearest $10 dollars is $180 as the number in the 1s column is greater than 5.  Because of this, you round up to get the nearest $10.  

Total bill equals $180

(a) The printer will print 3.5 pages per minute.

(b) It will plant 0.13 acres of seed per pound.

What is a unit rate?

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one.

(a) If a color printer prints 14 pages in 4 minutes.

   So it will print = 14/4

                           = 3.5 pages per minute

(b) If it takes 23 pounds of seed to completely plant a 3 - acre field

  So it can plant = 3/23

                           = 0.13 acres per pound.

Hence,

(a) The printer will print 3.5 pages per minute.

(b) It will plant 0.13 acres of seed per pound.

Answer: m = 22

Step-by-step explanation:

First, you subtract $2.50 from the total of $79.50 (because that is the static fee) to get $77.00. Now, because every mile is $3.50 and we want to find the number of miles, we divide $77 by $3.50 to get 22. (An easy way to do this mentally is to divide 77 by 7 and multiply by 2.) Therefore, m = 22.

Answer:

Step-by-step explanation:

You want the (a) post-order, and (b) pre-order list of visited vertices in a traversal of the tree described by {root, left, center, right}: {d, f, {b, i, h, e}, {a, {c, g}}}.

A tree is traversed in post-order by visiting the left branch, center branch, and right branch before the root. This is accomplished recursively.

For the given tree, the root 'd' has left branch 'f' which has no branches. That means node 'f' is reported first.

The middle branch goes to 'b' which has three branches. Those are reported before their root 'b'.

The right branch from root 'd' goes to 'a', which has branch 'c' going to 'g'. So, 'g' is reported, then 'c', then 'a'.

Finally, 'd' is reported.

Hence, the post-order traversal is f, i, h, e, b, g, c, a, d.

The pre-order traversal reports the root node, then the left, center, and right nodes, recursively. The vertices are effectively visited in the order in which we have defined the tree above: d, f, b, i, h, e, a, c, g.

The area represents the aim tariff revenue the United States government collects is D. f

Tariffs are taxes levied by the government of a country or a supranational union on goods imported or exported. Import duties, in addition to being a source of revenue for the government, can also be a form of foreign trade regulation and policy that taxes foreign products in order to encourage or safeguard domestic industry.

Tariffs serve three primary functions: they generate revenue, they protect domestic industries, and they correct trade distortions (punitive function). The revenue function stems from the fact that tariff revenue provides governments with a source of funding. This was illustrated as f in the diagram.

Answer: 4 red and 12 blue

Step-by-step explanation: Answer to 9

We know that for every red rose, he plants 3 blue flowers. The rate is 1:3. If he grows 16, there will be 4 red roses and 12 blue ones. This is because the rate is 1:3 then there are 4 flowers in all. This is 1/4 of how much he wants to grow. So multiply each type of plant by 4. 1 times 4 is 4, so there are 4 red ones. 3 times 4 is 12, so there are 12 blue ones. Hope this helps!

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

Two congruent parallelograms are joined along their base to make the shape below.

Now,

We know that;

2 identical parallelogram whose area = 2 (Base x Height)

And, 2 identical right triangle = base x height

And, 1 rectangle = length x width

So, We get;

In parallelogram;

Base = 15 cm

Height = 11 cm

Hence, We get;

Area = 2 (15 x 11)

       = 330 cm²

And, Area of two identical right triangle;

Base = 11 cm

Height = 11 cm

Hence, Area = 11 × 11
