the groups generated by two elements of order 2 are K4  and dihedral group.

We are given that G be  a finite group with  x, y belong to G have two elements of order two.

We have to prove that <x,y> is either abelian or isomorphic  to a dihedral group.

<x,y> means the group generated by two elements of order 2.

We know that  Zn is a cyclic group and  number of elements of order 2 is always odd in number and generated by one element  .So , given group is not isomorphic to Zn

But we are given that two elements of order 2 in given group

Therefore, group G can be K4 or dihedral group

Because the groups generated by two elements of order 2 are K4  and dihedral group.

We know that  is abelian group of order 4 and every element of K4  is of order 2 except identity element and generated by 2 elements of order 2 and dihedral group can be  also generated by two elements of order 2

Hence, <x,y> is isomorphic to K4 or D2.

The value of y in each case are 18,8 and 4 respectively.

Given equation:-

y = -x + 9

Values of x = {-9, 1, 5}

We have to find the corresponding values of y for each value of x.

Putting x = -9 in the given equation, we get,

y = -(-9) + 9 = 9 + 9 = 18

Putting x = 1 in the given equation, we get,

y = -1 + 9 = 8

Putting x = 5 in the given equation, we get,

y = -5 + 9 = 4

The slope of the line passing through the coordinates (2, 12) and (4, 3) is -9/2.

Slope is simply expressed as change in y over the change in x.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Given the data in the question;

Point 1( 2, 12 )

Point 2( 4,3 )

To determine the slope, plug the given x and y values into the slope formula and simplify.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Slope m = ( 3 - 12 )/( 4 - 2 )

Slope m = ( -9 )/( 2 )

Slope m = -9/2

Therefore, the slope of the line is -9/2.

Checking if the results of the following divisions are true or false.

a) -5/-1 = 5 ↔ True

The fraction, (remembering that it is a division), -5/-1​ can be simplified to 5 by removing the negative sign from the numerator and denominator.

b) (0/-4) = 0 ↔ True

We know that any number divided by zero, the result will always be zero.

c) -3/1 = -3 ↔ True

Any number divided by one equals the same number.

d) -8/0 = 0 ↔ False

A normal number simply cannot be divided by 0.

The three previous divisions are true, that is, your answers are correct. While the last one can't, since it can't be divided by 0, this one is false.

Dimensions of rectangle after dilation of scale factor 7/8 will be

[tex] (\frac{7}{2},14),  (\frac{-7}{2},14),  (\frac{-7}{2},-14),  (\frac{7}{2},-14) [/tex]

Dilation means the area of any rectangle increases or decreases due to change in it's dimensions but the shape of that rectangle will remain same.

Now Consider the point of dilation as the center of rectangle and assume that the center of given rectangle is at the origin.

As given the length and width of rectangle is 32ft and 8ft respectively.

∴ The Dimensions of rectangle will be (4,16), (-4,16), (-4,-16) and (4,-16).

Now As the rectangle is diluted by the factor of 7/8.

So Now New Dimensions are Calculated by simply multiplying the available dimensions with the scale factor of dilation.

∴ new Dimension after dilation will be

[tex] (4(\frac{7}{8}),16(\frac{7}{8})), (-4(\frac{7}{8}),16(\frac{7}{8})), (-4(\frac{7}{8}),-16(\frac{7}{8})), (4(\frac{7}{8}),-16(\frac{7}{8})) [/tex]

∴ Dimension after dilution will be ;

Considering the area and the perimeter of a square, it is found that:

Each length of the large square floor is of 21 meters, and each length of the small square floor is of 3 meters.

Supposing a square of side length s, the area and the perimeter are given as follows:

The area of the figure is given by the subtraction of the area of the large square, of side length x, by the area of the small square, of side length y, hence:

A = x² - y²

x² - y² = 432.

The perimeter of the figure is the perimeter of the square of side length s added to two edges of the smaller square of side length s, hence:

ANSWER

EXPLANATION

Step 1: Given that:

Step 2: Simplify matrix D

Hence, matrices C and D are equal.

Answer:

perpendicular

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{2}{3}[/tex] x + 5 ← is in slope- intercept form

with slope m = - [tex]\frac{2}{3}[/tex]

3x - 2y = 4 ( subtract 3x from both sides )

- 2y = - 3x + 4 ( divide through by - 2 )

y = [tex]\frac{3}{2}[/tex] x - 2 ← in slope- intercept form

with slope m = [tex]\frac{3}{2}[/tex]

• Parallel lines have equal slopes.

clearly the slopes are not equal, so not parallel.

• the product of the slopes of perpendicular lines = - 1

- [tex]\frac{2}{3}[/tex] × [tex]\frac{3}{2}[/tex] = - 1

then the lines are perpendicular to each other.

Answer:

The lines are perpendicular.

Step-by-step explanation:

[tex]3x -2y=4[/tex]

Step 1: Add -3x to both sides.

[tex]3x-2y+-3x=4+-3x[/tex]

[tex]-2y=-3x+4[/tex]

Step 2: Divide both sides by -2.

[tex]\frac{-2y}{-2} =\frac{-3x+4}{-2}[/tex]

[tex]y=\frac{3}{2} x-2[/tex]

Finally...

[tex]y=\frac{3}{2} x-2\neq y=-\frac{2}{3} x+5[/tex] so the lines are not parallel.

However, [tex]\frac{3}{2}[/tex] is the opposite reciprocal of [tex]-\frac{2}{3}[/tex], so, the lines are perpendicular.

The equation of the given linear function passing through two points is

y = 6 -2x.

Let (x₁, y₁) and (x₂, y₂) be two points on the given linear function whose equation in variables x and y is given by formula below.

(y -  y₁) = {(y₂ -y₁)/(x₂-x₁)} (x -x₁)

Given that  f is a linear function ,

f(-3) = 12

f(6) = -6

⇒(x₁, y₁) = ( -3,12)

  (x₂, y₂) = ( 6,-6)

Thus the equation of the linear function is :

⇒ y - 12 = { ( -6-12)/(6-(-3))} ( x - (-3))

⇒ y - 12 = { -18/ 9} ( x +3)

⇒ y - 12 = -2 ( x+3)

⇒ y = 12 -2x - 6

⇒ y = 6 -2x

Step-by-step explanation:

//////////////////////////////

Answer:

Step-by-step explanation:

A, B:  Define the Variables and Write Equations

Let T be the number of toppings.

Option 1:  $3 + $0.75*T

Option 2:  $4 + $0.50*T

C.  Graph the System

See the attached graph.  The intersection point is (4,6).  This means that 4 toppings will result in a cost of $6 for both yogurt options.

D.  Solution to the Problem

The solution is given above, but we can also solve using equations, instead of graphing.  We want the value of T that will make these expressions equal:

$3 + $0.75*T = $4 + $0.50*T

$0.25*T = $1

T = 4 toppings

=============

CHECK:

For 4 toppings:

Option 1:  $3 + $0.75*T

                  $3 + $0.75*(4)

                  $3 + $3 = $6

Option 2:  $4 + $0.50*T

                  $4 + $0.50*(4)

                  $4 + $2 = $6

Four toppings will make both options equal in cost.

E:  Is the solution reasonable?

Yes.  The cheaper option ($3) has a more expensive topping, so at some point (at 4 toppings) it will be the same price as the second option, with a higher initial price, but with cheaper toppings.

Expressing y in terms of x gives y = x - 19/ 6

Subject of formula can be defined as the variable that is being expressed in terms of other variables in an equation, function or expression.

It is also described as the variable that is being worked out in an expression or equation.

It is made to stand alone on on side of the equality sign.

We have the equation;

6(x-y) = 19

To make 'y' the subject of formula, let's take the following steps;

Divide both sides by 6, we have;

x - y = 19/ 6

now, take the variable 'x' over the equality sign

-y = 19/ 6 - x

Divide both sides by -1

y = x - 19/ 6

Hence, the equation is y = x - 19/ 6
