Answer:

a+(−4)=−13

a - 4 = - 13

a = -13 + 4

a = -9

hope it helps!

Answer: The value of a is -9.

Step-by-step explanation;

Step 1. Negative times positive is negative. a - 4 = -13.

Step 2. Add four to both sides. a - 4 + a = -13 + 4.

Step 3. Simplify. a = -9.

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.

Answer:

y = x - 3

Step-by-step explanation:

From the table attached,

Scatter plot given in the graph is correct.

Let the equation of the line passing from a point (x', y') is,

y - y' = m(x - x')

m = slope

Slope of the line passing through two points [tex](x_2,y_2)[/tex] and [tex](x_1,y_1)[/tex] is given by,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Therefore, slope of the line passing through the points (11, 8) and (12, 9) will be,

m = [tex]\frac{(9-8)}{(12-11)} =1[/tex]

Therefore, equation of the line passing through (11, 8) will be,

y - 8 = 1(x - 11)

y = x - 11 + 8

y = x - 3

Answer:

B

Step-by-step explanation:

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).

Answer:

s=2r

Step-by-step explanation:

Solution:

Given;

2q-r=p

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

PROVED

If you want any other solutions follow me

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.
