The solution of the linear equation 5x + y =8 and -6x + 2y = -4 will be (1.25, 1.75).

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The linear equation is given below.

5x + y = 8                        ...1

-6x + 2y = -4                   ...2

From equations 1 and 2, then we have

- 6x + 2(8 - 5x) = - 4

- 6x + 16 - 10x = - 4

- 16x = - 20

16x = 20

x = 1.25

The value of 'y' is given as,

5(1.25) + y = 8

6.25 + y = 8

y = 8 - 6.25

y = 1.75

The solution of the linear equation 5x + y =8 and -6x + 2y = -4 will be (1.25, 1.75).

Therefore , the solution of the given problem of triangle comes out to be KY = 16/3 inches , ZJ = 8 inches and  LY =2.66 inches.

The fact that a triangle contains four or segments qualifies it as a polygon. It is an elementary geometric form. Triangle ABC is the name given to a square with angles A, B, or C. Euclidean geometry creates one plane and square when side are not collinear. It is a polygonal if a triangle includes three sides + three corners. The intersection of a triangle's three sides is at its corners. Three triangle angles added together equal 180 degrees.

Here,

Given : A triangle XYZ

side length XY = 8 inches

and ZX = 12 inches

So,

Using centroid theorem:

We get

=> KY = 2/3 * 8

=> KY = 16/3 inches

and

=> ZJ = 2/3 * 12

=> ZJ = 8 inches

and For LY

=>  8 - 16/3

=> 2.66 inches

Therefore , the solution of the given problem of triangle comes out to be

KY = 16/3 inches , ZJ = 8 inches and  LY =2.66 inches.

When dividing the polynomial 3x^2 + 8x -3 by x + 3, we get the quotient as 3x - 1.

The given polynomial is 3x^2 + 8x -3.

First we choose a term to multiply with the first term of the divisor such that we get the first term of the polynomial:

(x)(3x) = 3x^2

Thus, we multiply the divisor (x+3) by 3x which gives 3x^2 + 9x.

Now we subtract this from the polynomial which gives -x -3.

In the same way we multiply the divisor by -1 which gives -x-3. Subtracting the same from the remaining polynomial -x -3 we get the remainder 0.

Thus, the quotient is 3x - 1.

The perimeter of the given figure is 36.84 ft.

The perimeter is defined as the sum of all the sides of the two-dimensional figure. The perimeter for the given figure will be the sum of all the sides.

The perimeter of a closed shape is the overall length of the boundary. As a result, the perimeter of that shape is determined by adding up all of its sides. Therefore, Perimeter(P) = Sum of All Sides is the perimeter formula.

The perimeter will be calculated as:-

Perimeter = ( 3 x 3 ) + ( 3 x 3 ) +  ( 2πr )

Perimeter =  9 + 9 + ( 2π x 3)

Perimeter = 18 + 18.84

Answer:

On Saturday, Matt practiced for 11 hours, and on Sunday, he practiced for 2 hours. So the total time Matt practiced on Saturday and Sunday is 11 hours + 2 hours = 13 hours.

On Monday, Matt practiced for half the time he practiced on Saturday and Sunday combined. To find out how long Matt practiced on Monday, we can divide the total time he practiced on Saturday and Sunday by 2.

13 hours / 2 = 6.5 hours

So, Matt practiced for 6.5 hours on Monday.

6.5 hours in fraction form can be expressed as 13/2 hours.

You can also express it as 6 + 1/2 = 6 1/2 hours.

The domain and the range of y = 12x - 35 are the set of all real numbers

from the question, we have the following parameters that can be used in our computation:

y = 12x - 25

There is no restriction on the input values, x

So, the domain of y = 12x - 35 is all real numbers, since there is no restriction on the input (x).

The range of y = 12x - 35 is also all real numbers, since the output (y) can be any real value, depending on the input (x).

This can be seen by considering that for any real number x, the output y = 12x - 35 will also be a real number.

The average speed that Antti must maintain for the last 8 km of the race is 9.6 km/h. The result is obtained by using the formula for speed of a moving object

Speed is the rate of change in position of an object without considering the direction. It is a scalar quantity that measures the distance travelled per unit of time. It can be expressed as

s = d/t

Where

To win the 10 km race, Antti's goal is finish in one hour. He completes the first 2 km at the average speed of 12 km/h. Determine the average speed that Antti must maintain for the last 8 km to reach the goal!

We call an average speed in that situation because running can't be constant in nature. So, we use the formula for speed.

The time needed for the first 2 km is

s₁ = d₁/t₁

12 = 2/t₁

t₁ = 2/12

t₁ = 1/6 hour

The remaining time is

t₂ = 1 - t₁

t₂ = 1 - 1/6

t₂ = 5/6 hour

With the remaining time, Antti should sprint at the average speed of

s₂ = d₂/t₂

s₂ = 8/(5/6)

s₂ = 8 × 6/5

s₂ = 9.6 km/h

Hence, Antti must maintain the speed of 9.6 km/h for the last 8 km of the race.

Step-by-step explanation:

To get the cost per desk, divide the total cost by the number of desks.

R840 000 x 3,450 desks = R242.86 per desk for Provider 1.

R760 000 R2250 desks = R338.89 per desk

According to the aforementioned computation, Provider 1 is less expensive than Provider 2 since the cost per desk is R242.86 vs R338.89 for Provider 2.

As a result, Provider 1 is less expensive than Provider 2.

A quadratic equation that can be written in the form ax^2 = b can be solved using the square root method.

Here are the steps of the square root method:

Take the square root of both sides of the equation, giving you √(ax^2) = √(b)

Solve for x by dividing both sides of the equation by √a.

If the value of b is positive, the solutions will be x = √(b/a) and x = -√(b/a).

For example, to solve the equation 4x^2 = 16, we can use the square root method as follows:

√(4x^2) = √(16)

x = ±√(16/ 4)

A repeating decimal or recurring decimal is the decimal representation of a number with periodic digits and an indefinitely repeated component that is not zero.

When a collection of decimal terms must be repeated uniformly, it is known as repeating decimals.

The decimal representation of a number with periodic digits and an infinitely repeated component that is not zero is called a repeating decimal or recurring decimal. Only when a number's decimal representation repeats or terminates can it be demonstrated that the number is rational.

Decimal values that repeatedly occur are known as recurring decimals (also known as repeating decimals). The customary behavior when a decimal expires and so ceases is not the case here. Therefore, 0.75 would be a repeating decimal since it would proceed indefinitely up to 0.755555 rather than ending at 0.75 like the previous example.
