Answers

Answer 1

Answer: y = 6x

Step-by-step explanation:

Answer 2

Answer:

y = 6x

In real-world terms
x = number of sandwiches

y = total cost of x sandwiches in dollar amounts

Step-by-step explanation:

The first piece of advice I have for you is to have confidence in yourself that you will succeed. That is what learners and tutors here at brainly are for. To help out.

Now to explanation of the problem and solution
The linear equation of a graph can be written in a couple of ways. On ios the standard form which is of the form
Ax + By = C where A, B and C are constants

The other is in slope-intercept form which is written as
y = mx + b

Here m is the slope which is also referred to as rise/run. I will explain these terms as we solve the problem

b is the y-intercept. This is the y-value at which the line crosses the y-axis. It corresponds to the value of y when x = 0

Sometimes the graph will not show the complete line so we cannot determine where the line crosses the y-axis. In this case this determination is a cinch

Looking at the graph, we see the line crosses the y-axis at (0,0) which is the origin

Therefore the y-intercept is 0 and hence b=0

Hence we get the line equation as

y = mx + b
==> y = mx + 0
==> y = mx

Let's find m, the slope:
Take any two points on the line. Here two points have been identified as (1, 6) and (4, 24)

The difference in y-values for these two points is 24 - 6 = 18.
This difference in y-values is known as the rise since it is measured vertically

The corresponding difference in x values is 4 - 1 = 3
This is referred to as run because it is measured horizontally

The slope m = rise/run
Here m = 18/3 = 6

Therefore plugging in m = 6 the equation in slope-intercept form is
y = 6x

Slope has another meaning. It signifies the rate of change
In this particular case in real-world terms it means that the cost of sandwiches is proportional to the number of sandwiches

Every sandwich you purchase will cost you $6 more

So the cost per sandwich is $6

For 1 sandwich -→ $6,

For 2 sandwiches → $12

For 7 sandwiches → $42

and all this is clearly evident in the graph

Hope that helps you and good luck on all your subjects

At the beginning of a snowstorm, Abigail had 12 inches of snow on her lawn. The snow then began to fall at a constant rate of 0.5 inches per hour. Assuming no snow was melting, how much snow would Abigail have on her lawn 5 hours after the snow began to fall? How much snow would Abigail have on her lawn after tt hours of snow falling?

Answers

The snow on the lawn after 5 hours is 14.50 inches.

The snow on the lawn after tt hours is 12 + 0.5tt inches

How much snow is on the lawn?

The equation that represents the amount of snow after a number of hours is a linear equation. A linear equation is an equation that has a single variable that is raised to the power of one.

The form of the equation is:

Total snow = snow on the lawn + (rate at which the snow falls x number of hours)

Snow after 5 hours = 12 + (0.5 x 5)

= 12 + 2.5 = 14.50 inches

Snow after tt hours = 12 + (0.5 x tt)

= 12 + 0.5tt inches

Answer:

v = 21

Step-by-step explanation:

Suppose v varies directly as g, meaning that there is a constant k such that v = kg. If v = 70 when g = 30, then we can use this information to find the value of k:70 = k * 30k = 70 / 30k = 7 / 3Now that we have the value of k, we can use it to find v when g = 9:v = kgv = (7 / 3) * 9v = 21So when g = 9, v = 21.In conclusion, by finding the value of the constant of proportionality k and using the formula v = kg, we determined that when g = 9, v = 21.

The false statement is (a) P( A^c n B^c)=P(A^c) P(B^c). The probability of the intersection of complements is generally not equal to the product of individual complements.

The misleading assertion including p, and the erratic occasions An and B is (a) P( A^c n B^c)=P(A^c) P(B^c).

This assertion is bogus in light of the fact that by and large, the likelihood of the convergence of the supplements of two occasions, A^c and B^c, isn't equivalent to the result of their singular supplements.

For instance, assume we flip a fair coin. Let A be the occasion of getting heads and B be the occasion of getting tails. Then, P(A) = P(B) = 1/2, so P(A^c) = P(B^c) = 1/2. In any case, A^c and B^c are a similar occasion (getting heads or tails, separately), so P(A^c n B^c) = P(A^c) = 1/2. Then again, P(A^c) P(B^c) = (1/2)(1/2) = 1/4, which isn't equivalent to P(A^c n B^c).

Consequently, proclamation (a) is misleading.

Now do 545 x 0.91

Answer: 495.95

ANSWER:The original price of the antique was £500.EXPLANATION:

Let's assume that the original price of the antique was x.

We know that the antique was sold at a profit of 9%, which means that the selling price is 109% of the original price:

[tex]Selling \: price = Original \: price + Profit[/tex]

[tex]£545 = x + 0.09x \\ £545 = 1.09x[/tex]

To find the original price, we can divide both sides of the equation by 1.09:[tex]x = \frac{545}{1.09} [/tex]

[tex]x = 500[/tex]

Therefore, the original price of the antique was £500.

Please help

Answers

{2x + y = 2

{5x + 3y - 9

Solution: We can solve this system of equations either by substitution or elimination method. Here, let's use substitution method.

From equation 1, we have: y = -2x + 2

Substituting this in equation 2, we get: 5x + 3(-2x + 2) - 9 = 0

Expanding the right-hand side, we get: 5x - 6x + 6 - 9 = 0

Simplifying further, we get: -x + (-3) = 0

Adding x to both sides, we get: -3 = x

Substituting this value of x in y = -2x + 2, we get: y = -2(-3) + 2 = 6

So, the solution to the system of equations is (x, y) = (-3, 6)

{5x - 2y = -2

{3x + 4y - 30

Solution: We can solve this system of equations by either substitution or elimination method. Here, let's use elimination method.

We can multiply equation 1 by 3 and equation 2 by 2, to make the coefficients of y same in both equations. Doing this, we get:

15x - 6y = -6

6x + 8y - 60 = 0

Adding these two equations, we get: 21x + 2y - 60 = 0

Simplifying further, we get: 21x = 60 + 2y

Dividing both sides by 21, we get: x = (60 + 2y)/21

Substituting this in equation 1, we get: 5((60 + 2y)/21) - 2y = -2

Expanding the right-hand side, we get: 60/21 + 10/21 y - 2y = -2

Simplifying further, we get: 60/21 + (-12/21) y = -2

Adding 12/21 y to both sides, we get: 60/21 = (-2) + (12/21) y

Subtracting -2 from both sides, we get: 62/21 = (12/21) y

Dividing both sides by 12/21, we get: y = 62/12 = 5 1/6

Substituting this value of y in x = (60 + 2y)/21, we get: x = (60 + 2(5 1/6))/21 = (60 + 11 1/3)/21 = (71 1/3)/21 = 71/21 + 1/63

So, the solution to the system of equations is (x, y) = (71/21 + 1/63, 5 1/6)

2. The area of a garden plot can be represented by
the expression 85.2z - 58.8. The garden will be
divided into six sections for planting six different
vegetables. The sections will be equal in area.
Write an expression that represents the area of
each section.

Answers

The expression that represents the area of each section is 14.2z - 9.8.

What is area ?

To find the area of each section, we need to divide the total area of the garden plot by the number of sections, which in this case is six.

The expression for the area of each section can be obtained by dividing the expression for the total area by 6:

(area of each section) = (total area of garden plot) / 6

(area of each section) = (85.2z - 58.8) / 6

Simplifying this expression, we can divide both terms by 6:

(area of each section) = 14.2z - 9.8

Therefore, the expression that represents the area of each section is 14.2z - 9.8.

what is 250lb in kg ?

Answers

Using the formula to convert pounds to kilogram,

We know that :

1 lb/ Pound = 0.453592 kilogram

therefore,

250 lbs/ Pound = 113.398 kilogram.

Using the formula to convert pounds to kilograms, you find that 250 pounds equals 113.398 kilograms

To convert 250 pounds (pounds) to kilograms (kg), you must use the conversion factor 1 pound = 113.398 kilogram.

Therefore,

we multiply 250 pounds by 86.18 kg/lb to get the equivalent weight in kilograms:

250 pounds x 0.45359237 kg/lb = 113.398 kilogram

Therefore,

250 pounds is 113.4 kilogram.

To understand the conversion factor, you need to know that pounds and kilograms are units of mass, but are used in many parts of the world. In the United States and some other countries, the accepted unit of mass is the pound, while most other countries use the kilogram.

A conversion factor connects the number of pounds to the number of kilograms, so you can easily convert from one unit of measure to another. It is important to use the correct conversion factor for accurate conversion.

According to a Manila police, two people were killed when the 1,000 kg car illegally drag racing at a speed of 30 m/s had a head on collision with a 2,000 kg truck whose driver fell asleep as it traveled 20 m/s. Which vehicle has received the greater force?

Answers

Answer: To determine which vehicle received the greater force, we need to calculate the momentum change for each vehicle during the collision. The force experienced by a vehicle during a collision is equal to the rate of change of its momentum.

First, let's calculate the initial momentum for each vehicle:

The car has a mass of 1,000 kg and a velocity of 30 m/s, so its initial momentum is 1,000 kg * 30 m/s = 30,000 kg m/s.

The truck has a mass of 2,000 kg and a velocity of 20 m/s, so its initial momentum is 2,000 kg * 20 m/s = 40,000 kg m/s.

Next, let's calculate the final momentum for both vehicles after the collision:

The car and truck collide head-on, so their velocities will become zero after the collision. So the final momentum for both vehicles will be zero.

Finally, we can calculate the rate of change of momentum for each vehicle:

The rate of change of momentum for the car is equal to its final momentum minus its initial momentum, or 30,000 kg m/s - 0 kg m/s = 30,000 kg m/s.

The rate of change of momentum for the truck is equal to its final momentum minus its initial momentum, or 0 kg m/s - 40,000 kg m/s = -40,000 kg m/s.

Since the magnitude of the rate of change of momentum for the truck is greater than the magnitude of the rate of change of momentum for the car, the truck has received the greater force.

What is the cost and area of the mat

Answers

The costs and areas of the mat are

Mat area = 2x + 2y + 4; Cost = 0.1x + 0.1y + 0.2Mat area = 4x + 4y + 16; Cost = 0.2x + 0.2y + 0.8

How to determine the cost and area of the mat

Represent the dimensions of the frame with

Length = x

Width = y

So, the frame area is

Area = xy

When the mat is 1 inch from the frame, we have

Whole Area = (x + 1 + 1) * (y + 1 + 1)

Whole Area = (x + 2) * (y + 2)

Expand

Whole Area = xy + 2x + 2y + 4

So, the mat area is

Mat area = xy + 2x + 2y + 4 - xy

Mat area = 2x + 2y + 4

The cost is

Cost = 0.05 * (2x + 2y + 4)

Cost = 0.1x + 0.1y + 0.2

When the mat is 2 inches from the frame, we have

Whole Area = (x + 4) * (y + 4)

Expand

Whole Area = xy + 4x + 4y + 16

So, the mat area is

Mat area = xy + 4x + 4y + 16 - xy

Mat area = 4x + 4y + 16

The cost is

Cost = 0.05 * (4x + 4y + 16)

Cost = 0.2x + 0.2y + 0.8
