Step-by-step explanation:

The counter example for the system of equation is given by x + y = 1 ,

-x - y = 1 has the result 0 = 2 but ( 0, 2 ) is not the solution of the equation. It proves statement is false.

As given in the question,

Form the given system of equations , using elimination method to get the solution of the equation which shows the result 0 = 2 is as follow:

a. x + y = 1

- x - y = -1

0 = 0

Not the required result.

b. x + y = 1

  x - y = 1

 2x = 2

Not a required result.

c. x + y = 1

  - x - y = 1

     0 = 2

Required result.

Analyze : substitute x = 0 and y = 2 in any one equation

0 + 2 = 1

or -0 -2 = 1

Both the equations proves that statement is false.

d. x + y = -1

  -x -y = -1

   0 = -2

Not a required result.

Therefore, the system of equation of option c.  x + y = 1 , -x - y = 1 has the result 0 = 2 and proves it is the false statement.

If you dilate by a scale factor of k, and do so about the origin, then you use the rule \((x,y) \to (kx,ky)\). We multiply the scale factor k by each coordinate.

We have the following given points:

Step-by-step explanation:

If the jeans are on sale for 45% off, then they will cost 55% of the original price (100%-45%=55%).

Therefore, the sale price is:

85×55%

Change % into a decimal

= 85×0.55

= 46.75

Therefore, the sale price of the jeans is 46.75 dollars.

Answer:

RA = 24

Step-by-step explanation:

Since the triangle is isosceles ( 2 equal sides ) , then LU is a perpendicular bisector , so

AU = RU , that is

4r = 18 - 2r ( add 2r to both sides )

6r = 18 ( divide both sides by 6 )

r = 3

Then

RA = 18 - 2r + 4r = 18 + 2r = 18 + 2(3) = 18 + 6 = 24

m increased by %8 so it'll be

and t will be

so G =

The number of weeks required to complete the project with crashing cost less than $3,500 is: W2 = W1*(R + $3,500)/(C + $3,500)

What is algebraic expression?

An algebraic expression is a mathematical phrase or equation that contains variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation.

To determine the number of weeks it will take to complete the project, we need to know the regular cost per week and the crashing cost per week.

Let's assume that the regular cost per week is $R, and the crashing cost per week is $C. We also know that Bragg's loses $3,500 in profit per week for every week the bakery is not completed. Therefore, the maximum amount Bragg's is willing to pay for crashing the project is $3,500.

If we denote the number of weeks required to complete the project with the regular cost per week by W1, and the number of weeks required to complete the project with the crashing cost per week by W2, then we have the following equation:

RW1 + $3,500(W2 - W1) = C*W2

where the left-hand side represents the total cost of completing the project with a combination of regular and crashing costs, and the right-hand side represents the total cost of completing the project with only crashing costs.

We want to find the minimum value of W2 that satisfies this equation.

Simplifying this equation, we get:

W2 = (RW1 + $3,500W1)/(C + $3,500)

W2 = W1*(R + $3,500)/(C + $3,500)

Therefore, the number of weeks required to complete the project with crashing cost less than $3,500 is:

W2 = W1*(R + $3,500)/(C + $3,500)

We can solve for W2 using the given values for R, C, and the desired maximum crashing cost of $3,500.

Answer:

They travelled the same distance and they spent the same amount of time from the 225 marker to 230 marker.

Step-by-step explanation:

Given

See attachment for graph

Required

The relationship between distance and time travelled by Kevin and Carrie

The straight line represents Kevin's journey while the curve represents Carrie's

From the graph, we can see that the straight line and the curve both start at the origin (0,0) and they both end at the same point (17,5)

Point (17, 5) represents the 230 marker (i.e. 225 + 5 - 230)

Since the line and the curve meet at this point, then they travelled the same distance and they spent the same amount of time.

To find the combined rate of all the individuals working together, you must add the individual rates.

When calculating the combined rate of individuals working together, you need to add up the individual rates. Each worker contributes their own rate of work or productivity, and by adding these rates together, you can determine the combined rate at which they are working collectively.

This allows you to assess the overall efficiency and output of the team or group. By summing up the individual rates, we have better understanding of the overall productivity and performance of the group.

69200000 in scientific notation is  6.92 × 10⁷.

Scientific notation is a form of presenting very large numbers or very small numbers in a simpler form.

Scientific Notation is a special way of writing numbers:

For example 800 is written as 8 × 10² in Scientific Notation.

Therefore, let's write the scientific notation of the number 69200000.

Hence,

69, 200, 000 = 6.92 × 10⁷

The logic is that we will count backwards until we meet the last number. Since we counted towards the left side, the exponent will be positive.
