The product of the matrices is given below.

[tex]\begin{bmatrix}6 & 0 & 3\\4 &0 & 2\\0&0&0\end{bmatrix}[/tex]

A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The [tex]\rm a_{ij}[/tex] element in a matrix, such as M, refers to the i-th row and j-th column element.

The matrices are given below.

[tex]\begin{bmatrix}3 & 6 & 1\\ 2 & 4 & 0\\ 0 & 6 & 2\end{bmatrix} \text{and} \begin{bmatrix}2 & 0 & 1\\ \end{bmatrix}[/tex]

The product of the matrices will be

[tex]\begin{bmatrix}3 & 6 & 1\\ 2 & 4 & 0\\ 0 & 6 & 2\end{bmatrix} \times \begin{bmatrix}2 & 0 & 1\\ \end{bmatrix} = \begin{bmatrix}6 & 0 & 3\\4 &0 & 2\\0&0&0\end{bmatrix}[/tex]

Thus, the product of the matrices is given below.

The required, x=-2 is the input value that produces the same output value for the two functions on the graph. Option B is correct.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

The statement "x = -2 input value produces the same output value for the two functions on the graph" means that if you plug in x = -2 into both functions, you will get the same output value for both of them. In other words, the two functions intersect at the point (-2, y), where y is the common output value for x = -2.

The graph of the two functions intersecting at the point (-2, 1), where the x-coordinate is -2 and the y-coordinate is the common output value for both functions. This means that if you draw a vertical line at x = -2, it will intersect the graph at the point (-2, 1) for both functions. Therefore, x = -2 is a vertical line of symmetry for the two functions at the point (-2, 1).

Step-by-step explanation:

because the linear line goes down we know it is negative

and its not 1/2 because it is rise over run. it runs 1 and rises 2 (or drops 2 because it is negative)

rise over run = -2/1 = -2

Answer:

[tex]\huge\boxed{\sf k = 2}[/tex]

Step-by-step explanation:

Coordinate = (x,y) = (2k-1,k)

This means that:

x = 2k - 1 and y = k

Put it in the given equation: 5x - 4y = 7

5(2k-1) - 4k = 7

10k - 5 - 4k = 7

6k - 5 = 7

Adding 5 to both sides

6k = 7+5

6k = 12

Divide both sides by 6

k = 2

Answer: Khloe could buy 3 bags of popcorn and 9 candies.

Step-by-step explanation:

\,\,\text{the number of bags of popcorn}

the number of bags of popcorn

y=

y=

\,\,\text{the number of candies}

the number of candies

\text{\textquotedblleft no less than 11 items"}\rightarrow \text{11 or more items}

“no less than 11 items"→11 or more items

Use a \ge≥ symbol

Therefore the total number of bags of popcorn and candies, x+yx+y, must be greater than or equal to 11:11:

x+y\ge 11

x+y≥11

\text{\textquotedblleft \$60 to spend"}\rightarrow \text{can spend \$60 or less}

“$60 to spend"→can spend $60 or less

Use a \le≤ symbol

One bag of popcorn costs $7, so xx bags of popcorn cost 7x.7x. One candy costs $4, so yy candies cost 4y.4y. The total 7x+4y7x+4y must be less than or equal to \$60:$60:

7x+4y\le 60

7x+4y≤60

\text{Solve each inequality for }y\text{:}

Solve each inequality for y:

\begin{aligned}x+y\ge 11\hspace{30px}& 7x+4y\le 60 \\[0.8em] y\ge 11-x \hspace{30px}& 4y\le 60-7x \\[0.8em] \hspace{30px}& y\le \frac{60-7x}{4} \\[0.8em] & y\le 15-\frac{7}{4}x\end{aligned}

(3, 9)

Since the point (3, 9(3,9) is inside the double shaded region, one possible solution to the system of inequalities would be:

Khloe could buy 3 bags of popcorn and 9 candies.

The system of inequalities are x + y ≥ 11 and 7x + 4y ≤ 60 and the solution is given by the point P ( 3 , 9 ) where x represents the number of bags of popcorn purchased and y represents the number of candies purchased

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let x represents the number of bags of popcorn purchased and y represents the number of candies purchased

Now , the total number of bags should be no less than 11

And , the inequality is

x + y ≥ 11   be equation (1)

And , cost of each popcorn bag = $ 7

So , the cost of x bags = 7x

And , cost of each candy bag = $ 4

So , the cost of y bags = 4y

The total amount with Khloe = $ 60

And , the inequality is

7x + 4y ≤ 60   be equation (2)

On graphing the inequalities , we can see that the point P ( 3 , 9 ) lies inside the solution

So , 7 ( 3 ) + 4 ( 9 ) ≤ 60

21 + 36 ≤ 60

57 ≤ 60

And , 3 + 9 ≥ 11

12 ≥ 11

Hence , the system of inequalities are solved and the graph is plotted

Solution:

Given;

r=q-s

or,q=r+s

p=q+2r

To prove: s=2r

Now,

2q-r=p

or,2(r+s)-r=q+2r

or,2r+2s-r=r+s+2r

or,r+2s=3r+s

or,s=2r

THANK YOU

By using the substitution method we can prove s = 2r.

Given,

2p - r = p

r = q - s

p = q + 2r

We need to prove s = 2r.

It is a method where we substitute the value of one variable in one equation for the same variable in the other equation.

Example:

x + 4 = y _____(1)

x = y - 4

x + 5 = 2y ______(2)

Putting x = y - 4 in (2)

y - 4 + 5 = 2y

-4 + 5 = 2y - y

1 = y

y = 1

Prove s = 2r.

We have,

2q - r = p ____(1)

r = q - s _____(2)

p = q + 2r ______(3)

From (1) and (2)

Substituting (2) in (1)

2q - (q - s) = p

2q - q + s = p

q + s = p _____(4)

Putting (4) in (3)

q + s = q + 2r

q - q + s = 2r

s = 2r

Hence proved.

Thus we can prove s = 2r.
