For the value of k is equal to 6, the system of equations,

kx + 3y - (k – 3) = 0 and 12x + ky - k = 0 have infinitely many solutions

Here we have equations

kx + 3y - (k – 3) = 0

12x + ky - k = 0

For a system of 2 linear equations,

a₁x + a₂y + a₃ = 0

b₁x + b₂y + b₃ = 0

They will have infinitely many solutions if

a₁/b₁ = a₂/b₂ = a₃/b₃

here,

k = a₁,          3 = a₂          - (k – 3) = a₃

12 = b₁         k = b₂           - k = b₃

Hence

k/12 = 3/k = (3 - k)/(-k)

Taking up

3/k = (3 - k)/(-k)

we get

3 = k - 3

or, k = 6

hence for k = 6, the equations will have infinite solutions.

The total cost of the fence will be £841. The solution is obtained using the concept of perimeter of triangle.

What is perimeter of triangle?

Any two-dimensional figure's perimeter is determined by the space surrounding it. By summing the lengths of the sides, we can determine the perimeter of any closed shape.

We are given a right-angled triangle with one angle 59° and the adjacent side as 145 meters.

We know that tan θ = Opposite side/Adjacent side

⇒ tan 59° = Opposite side/145

⇒ 1.66 = Opposite side/145

⇒ 241 meters(approx) = Opposite side

Now, using pythagoras theorem,

⇒Hypotenuse^2 = Base^2 + Perpendicular^2

⇒Hypotenuse^2 = 241^2 + 145^2

⇒Hypotenuse^2 = 58,081 + 21,025

⇒Hypotenuse^2 = 79,106

⇒Hypotenuse = 281 meters(approx)

Perimeter of triangle = Sum of three sides

⇒ Perimeter = 145 + 241 + 281

⇒ Perimeter = 667 meters

The fence costs £ 1.26 per meter

Total cost of fence = 1.26 * 667 = £840.42 = £841

Hence, the total cost of the fence will be £841.

Answer:

32.9 cm^2

Step-by-step explanation:

In the absence of a diagram, lets use the one shown in the attached worksheet.  The assumption is that the "blue areas" are the four sections of the circle that extend beyond the square boundaries.  The approach is to calculate areas for both the circle and the square.

Square = (11 cm)^2              =  121 cm^2

Circle = (3.14)*(14/2 cm)^2  =   153,9 cm^2

Subtract the square from the circle.  That removes all the circle area, except for the four sections outside the square.  The result is 32.9 cm^2

The formula for the sum rule is: P(A or B) = P(A) + P(B) - P(A and B)

The sum rule, also known as the addition rule of probability, states that the probability of any two events occurring together is the sum of the probability of each event occurring individually, minus the probability of them both occurring at the same time. The formula for the sum rule is:

P(A or B) = P(A) + P(B) - P(A and B)

where A and B are two events and P(A) and P(B) are the probabilities of each event occurring individually, and P(A and B) is the probability of both events occurring at the same time.

The sum rule is used when the two events are mutually exclusive, meaning that they cannot happen at the same time. In this case, P(A and B) = 0, so the formula becomes:

P(A or B) = P(A) + P(B)

The point (7, 10.5) is on the graph of both equations and satisfies the system of equations.

To find the solution to a system of equations, we need to find the values of x and y that satisfy both equations simultaneously.

The system of equations is:

y = 2x - 3.5

x - 2y = -14

We can begin by solving one of the equations for one of the variables, for example, we can solve the first equation for y:

y = 2x - 3.5

Next, we can substitute this expression for y into the second equation:

x - 2(2x - 3.5) = -14

This gives us:

x - 4x + 7 = -14

-3x = -21

x=7

Now we can substitute this value of x back into the first equation to find the corresponding value of y:

y = 2(7) - 3.5

y = 10.5

So the solution to the system of equations is x = 7, y = 10.5.

a) To find a formula for the sequence, we can use a difference table.

First, let's write out the first few terms of the sequence:

3, 14, 32, 60, 98, ...

Next, we'll create a difference table:

n | Term | Difference

1 | 3 |

2 | 14 | 11

3 | 32 | 18

4 | 60 | 28

5 | 98 | 38

We see that the difference is increasing by 10 each time, so our formula can be written as:

Term = 11n + 3

To check the formula, we can plug in a few values of n and see if it matches the terms in the sequence:

n = 1, Term = 11(1) + 3 = 14

n = 2, Term = 11(2) + 3 = 32

n = 3, Term = 11(3) + 3 = 60

The formula matches the terms in the sequence, so it is correct.

b) To find the next three terms in the sequence, we can use our formula:

n = 6, Term = 11(6) + 3 = 79

n = 7, Term = 11(7) + 3 = 90

n = 8, Term = 11(8) + 3 = 101

Answer: x = 6 and y = -9

Step-by-step explanation:

Solve by reduction method

7x + 2y = 24

8x + 2y = 30

We will multiply the first equation by 8, and the second equation by -7, then both equations must be added.

8(7x + 2y = 24)

-7(8x + 2y = 30)

Add these equations to eliminate x

  2y = -18

Then we solve 2y = -18 for y. (We divide by 2)

      2y/2 = -18/2

      y = -9

We place the found value of y , in one of the original equations y in order to solve for x.

7x + 2y = 24

7x + 2(-9) = 24

7x - 18 = 24

We add 18 to both sides.

  7x - 18 + (18) = 24 + (18)

       7x = 42

We add 18 to both sides.

 7x/7 = 42/7

Step-by-step explanation:

The given equations 3x - y + 8 = 0 and 6x - ky = -16 represent coincident lines if the value of k is 2.

Given the pair of equations is

3x - y + 8 = 0

6x - ky = -16 describes coincident lines.

We have to calculate the value of k.

We know that,

For a pair of linear equations in two variables a₁x + b₁y + c₁ = 0 and a₂x + b₂y + c₂ = 0,

If a₁/a₂ = b₁/b₂ = c₁/c₂, then the pair of linear equations is dependent and consistent.

We have, a₁ = 3, b₁ = -1, c₁ = 8

a₂ = +6, b₂ = -k, c₂ = +16

So, a₁/a₂ = 3/6 = 1/2

b₁/b₂ = -1/-k = 1/k

c₁/c₂ = 8/16 = 1/2

a₁/a₂ = b₁/b₂ = c₁/c₂ = 1/2

1/k = 1/2

k = 2

Therefore, the value of k is 2.
