Describe the possible values for x and y when ∣x − y ∣ > 0. What does it mean when ∣x − y ∣ = 0? Can ∣x − y ∣ < 0? Explain your reasoning.

Answer with explanation:

The equation, y=3 x,

y=Distance traveled

x =Total time

[tex]\frac{\text{Distance traveled}}{\text{Time}}=\frac{y}{x}=3\\\\ \frac{dy}{dx}={\text{Rate of change}}={\text{Velocity}}=3 {\text{unit of time}][/tex]

Also, in terms of straight line

Slope =3= uniform Velocity

Point (3,9) and (5,15) represents Distance traveled in 3 (unit of time) =9 unit ,and 15 unit=Distance traveled in 5 (Unit of time).

→Alonso is moving with uniform speed=3 (unit of time), as velocity remains constant in the entire process.

The graph of line y = 3x, y represents distance and x represents the time and the point (3,9) repersents the distance covered by Alonso's is 9 unit in 3 unit of time and the point (5,15) repersents the distance covered by Alonso's is 15 unit in 5 unit of time.

Given :

y = 3x , represents Alonso's walking speed.

If y = 3x represents Alonso's walking speed than y represents distance and x represent time. The graph of y = 3x is attached below.

The point (3,9) on the line (y = 3x) represent that at 3 unit of time the distance covered by Alonso's is 9 unit.

The ponit (5,15) on the line (y = 3x) represent that at 5 unit of time the distance covered by Alonso's is 15 unit.

Therefore, in the graph of line y = 3x, y represents distance and x represents the time and the point (3,9) repersents the distance covered by Alonso's is 9 unit in 3 unit of time and the point (5,15) repersents the distance covered by Alonso's is 15 unit in 5 unit of time.

Answer:

The correct option is:   $1.45 + $0.55x ≤ $35 ;  x ≤ 61 miles

Step-by-step explanation:

Suppose, the number of miles Ariel can travel [tex]=x[/tex]

The cab charges $1.45 for the flat fee and $0.55 for each mile. So, the total charges for [tex]x[/tex] miles [tex]=\$1.45+\$0.55x[/tex]

Given that, she has $35 to spend. That means, the total charges must be less than or equal to $35.

So, the inequality will be:   [tex]\$1.45+\$0.55x\leq \$35[/tex]

Solving the above inequality....

[tex]1.45+0.55x\leq 35\\ \\ 0.55x\leq 35-1.45\\ \\ 0.55x\leq 33.55\\ \\ x\leq \frac{33.55}{0.55}\\ \\ x\leq 61[/tex]

So, the number of miles Ariel can travel is 61 miles.

Answer:

Step-by-step explanation:

We have given the Sal's and Carrie's ages. We need to represents the table below using equation.

Sal    =    3     5    8    13   15

Carrie =   7    9    12   17    19

Out of given options, equation (3) should be followed. We can proof it as :

c = s + 4

Putting one by one the ages of Sal in the above equation to get Carrie's age.

1. c = 3 + 4 = 7

2. c = 5 + 4 = 9

3. c = 8 + 4 = 12

4. c = 13 + 4 = 17

5. c = 15 + 4 = 19

Hence, the correct option is (c).

Rich spent $8 on baseballs and $44 on basketballs for a total expense of $52. This application of buying multiple items at a given cost and then summing across categories demonstrates the distributive property in mathematics.

Rich bought two baseballs at a cost of $4 each. This cost could be represented as 2 * $4 = $8. He also bought two basketballs for $22 each. This cost could be represented as 2 * $22 = $44. By using the distributive law, we multiply the cost of each basketball or baseball with the quantity purchased and then adding the total costs together which is adding $8 and $44. Hence, the total is $8 + $44 = $52 which represents the total cost of the baseballs and basketballs that Rich bought. This is a clear demonstration of the distributive property where operations inside parentheses can be distributed over other operations.

Consider the Set A = {X | X is an even whole number between 0 and 2 } = [tex]\Phi[/tex].

Since, whole numbers are the set of numbers starting from zero upto infinity.

Even numbers are the numbers which are exactly divisible by '2'.

So, we have to find the even whole number between 0 and 2.

Since, only '1' is a whole number between 0 and 2 which is not an even number as '1' is not divisible by '2'.

Therefore, there is no even whole number between 0 and 2.

So, this set is empty.

Therefore, A = { X | X is an even whole number between 0 and 2} =  [tex]\Phi[/tex]

The distance between the two airports is 252 miles

What is Speed?

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the distance between the two airports be = D

Now ,

Let the first airport be = A

Let the second airport be = B

And , the speed from Airport A to Airport B averaged = 280 mph

The speed from Airport B to Airport A averaged = 120 mph

The total time taken for the journey = 3 hours

So , the value of Time T = 3 hours

So , the equation will be

Time = Distance / Speed

Since , the distance between the airports remains the same on the journey,

Time = D/280 + D / 120

Substituting the values in the equation, we get

D/280 + D / 120 = 3

The LCM of 280 and 120 is 840 , so

( 3D + 7D ) / 840 = 3

On simplifying the equation , we get

Multiply by 840 on both sides of the equation , we get

10D = 2520

Divide by 10 on both sides of the equation , we get

D = 252 miles

Therefore , the value of distance D from the equation is 252 miles

Hence , The distance between the two airports is 252 miles

Final answer:

By solving the equation 280t = 120(3 - t), we find that the time taken to fly to the city is 0.9 hours. Multiplying this by the speed of 280 mph, the distance between the two airports is determined to be 252 miles.

Explanation:

To find the distance between the two airports, we can use the formula distance = speed × time, but first, we need to find the time taken for each leg of the journey. Let t be the time (in hours) it takes for the plane to fly to the city at 280 mph. Hence, the time taken to return to the international airport at 120 mph will be 3 - t hours. We can establish the following equations based on this information:

To the city: 280t (since distance = 280 mph × t)

Returning: 120(3 - t) (since distance = 120 mph × (3 - t))

Since the distances are equal for both trips, we can set the equations equal to each other:

280t = 120(3 - t)

Solving for t, we get:

280t = 360 - 120t
400t = 360
t = 0.9

The time taken to fly to the city at 280 mph is 0.9 hours. Now we can find the distance:

Distance to the city = 280 mph × 0.9 h = 252 miles.

Therefore, the distance between the two airports is 252 miles.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The number of ways in which the password can be formed is 7,893,600.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Given that a computer system password requires five characters, all lowercase letters (remember there are 26 letters), and all the letters must be different. Therefore, if a letter is used once it can not be used again.

For the first place available options = 26 letter

Now, one letter is only used therefore, there are only 25 options available for the next place.

For the Second place available options = 25 letter

Now, two letters are only used therefore, there are only 24options available for the next place.

For the third place available options = 24 letter

Now, three letters are only used therefore, there are only 23 options available for the next place.

For the fourth place available options = 23 letter

Now, the four letter are only used therefore, there are only 22 options available for the next place.

For the fifth place available options = 22 letter

Further, the number of ways in which the password can be formed is,

Number of ways = 26 × 25 × 24 × 23 × 22 = 7,893,600

Hence, the number of ways in which the password can be formed is 7,893,600.
