Step-by-step explanation:

The system of equations represents the dependent because the solution to the system of equations has infinitely many solutions.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The system of equations are:

5x + y = 2

2y = 4 − 10x

The system of equations can be written as:

5x + y = 2 ..(I)

10x + 2y = 4 ...(II)

In equation (II) divide by 2

5x + y = 2 ..(III)

Equations (I) and (III) represent the same equation:

The system of equations represents the Dependent because the solution to the system of equations has infinitely many solutions.

Thus, the system of equations represents the dependent because the solution to the system of equations has infinitely many solutions.

Answers

Answer:

1. Reflection across y-axis and translated down 1 unit

2. 270 degree counterclockwise rotation and translated right three units.

Step-by-step explanation:

For number 1, when you reflect across the y-axis, the polygon is one unit above the intended location, so you would move it down one.

For number two, when you rotate it 270 degrees counterclockwise, it is to the left three units, so you would move it to the right three units.

Answers

Answer:

{x,y} = {33/19,-2/19}

Step-by-step explanation:

Answer: For 5x-3y=-11, the answer is y=11/3 + 5x/3.

For 2x-5y=-14, the answer is y=14/5 + 2x/5

Step-by-step explanation: Move all terms that do not contain y to the right side and then solve.

Givenf(x)=6(8−x)+5.
(a) What does the notation f (−2) mean? (b) What is the value of f (−2) ?

Answers

Answer:

b. 65

a. The notation f(-2) means that we want to evaluate the value of the equation when x = -2

Step-by-step explanation:

A. The notation f(-2) means that we want to evaluate the value of the equation when x = -2

B. We will simply substitute the value of 2 for x

f(x) = 6(8-x) + 5

f(-2) = 6(8 - (-2)) + 5

f(-2) = 6(8 + 2) + 5

f(-2) = 6(10) + 5 = 60 + 5 = 65

We add 12 to both sides
9x=13+14x+12
Simplify it we get
9x=4x+25
Subtract 4x from both sides
9x-4x=25
We simplify it and we get
5x=25
Divide both sides by 5
X=25/5
And we get x=5 as the answer

Find the coordinates of the midpoint of a segment with the given endpoints (7,0) and (2,4)

Answers

Answer:

[tex]MP= (4.5,2)[/tex] another way of writing [tex]MP= (\frac{9}{2}, 2)[/tex]

Step-by-step explanation:

[tex]MP= (\frac{x_1+x_2}{2})(\frac{y_1+y_2}{2})[/tex]

[tex]MP= (\frac{7+2}{2})(\frac{0+4}{2})[/tex] 7+2=9 0+1=1

[tex]MP= (\frac{9}{2})(\frac{2}{2})[/tex]  MP= (4.5,2)

The coordinates of the mid - point of XY will be -  M(4.5, 2)

We have two coordinate points - X(7, 0) and  Y(2, 4).

We have to find the coordinates of the mid - point of the line segment XY.

What is Mid - Point Theorem?

It states that a line with endpoint coordinates as - [x(1), y(1)] and

[x(2), y(2)] has its mid - point at the coordinates -

[tex]$x(m) =\frac{x(1)+x(2)}{2}[/tex]

[tex]$y(m) = \frac{y(1)+y(2)}{2}[/tex]

According to question, we have -

Assume that the coordinates of Mid - Point = M(h, k)

Coordinates of X= (7, 0)

Coordinates of Y= (2, 4)

Using the Mid - Point formula -

h = [tex]\frac{7+2}{2}[/tex] = 4.5

and

k = [tex]\frac{0+4}{2}[/tex] = 2

Hence, the coordinates of the mid - point of XY will be -  M(4.5, 2)

Step-by-step explanation:

So we have the equation:

[tex]4xz-4yz=5[/tex]

And we want to find the value of 5/4x in terms of x and y.

From our original equation, let's factor out a 4z from the left. So:

[tex]4z(x-y)=5[/tex]

Now, divide both sides by 4z:

[tex]x-y=\frac{5}{4z}[/tex]

Therefore, the expression that represents 5/4z is x-y.
