Considering the expression of a line, the equation of the line that passes through the pair of points (-3,5) and (1,-1) is y=-1.5x +0.5.

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope of the line can be calculated using:

m= (y₂ - y₁)÷ (x₂ - x₁)

Substituting the value of the slope and the value of one of the points, the value of the ordinate to the origin can be obtained.

In this case, being (x₁, y₁)= (-3, 5) and (x₂, y₂)= (1, -1), the slope m can be calculated as:

m= ( -1 -5)÷ (1 - (-3))

m= ( -1 -5)÷ (1 + 3)

m= (-6)÷ 4

m= -1.5

Considering point 2 and the slope m, you obtain:

-1= -1.5×1 + b

-1= -1.5 +b

-1 + 1.5= b

0.5= b

Finally, the equation of the line is y=-1.5x +0.5.

Answer:

The unit rate is 35 pages per minute.

Step-by-step explanation:

Divide 175 by 5, or 175/5  to get the unit rate, which is 35.

Answer:

Step-by-step explanation:

To solve this problem, we can use the formula:

distance = rate x time

Since Tina bicycles at a constant speed, we can simplify the formula to:

distance = speed x time

For the first 2 hours, Tina bicycles at a constant speed, so the distance she travels is:

distance = speed x time = s x 2

After taking a 1-hour break, Tina continues to bicycle at the same speed for another 2 hours, so the distance she travels is:

distance = speed x time = s x 2

Therefore, the total distance Tina travels over the 5-hour period is:

total distance = 2s + 2s = 4s

This means that the total distance Tina bicycles is directly proportional to the speed at which she travels. In other words, if Tina travels twice as fast, she will cover twice the distance in the same amount of time.

With this in mind, we can eliminate choices (A) and (B), which show linear relationships between distance and time. Since Tina is traveling at a constant speed, the graph of her distance should be a straight line with a positive slope.

Choice (C) shows a straight line with a positive slope, but the slope is too steep. This graph would indicate that Tina is traveling at a much faster speed than she actually is.

Choice (D) shows a straight line with a positive slope that is not as steep as (C). This graph accurately represents Tina's constant speed and shows the increase in distance after the break. Therefore, the correct graph is (D).

Example

It took Markus half an hour to drive home from work.  He averaged 34 miles per hour.  How far does Markus live from his work?

Solution

We are given that it takes 1/2 an hour for the trip.  This is a time:

       t  =  1/2

We are given that he averages 34 miles per hour.  This is a rate:

       r  =  34

We are asked how few he has traveled.  This is a distance.  We use the d=rt equation:

       d  =  rt

           =  (34)(1/2)

           =  17

Markus lives 17 miles from work.

there were 28,800 handshakes that occurred at the meeting.

How to solve the question?

In order to calculate the number of handshakes that occurred, we can use the formula for the sum of the first n-1 positive integers. The reason we use n-1 is because each person shakes hands with n-1 other people (themselves excluded).

The formula is:

(n-1) + (n-2) + (n-3) + ... + 1

where n is the number of people in the group.

In this case, n = 240, so we plug in:

(240-1) + (240-2) + (240-3) + ... + 1

Simplifying:

239 + 238 + 237 + ... + 1

We can see that this is an arithmetic series with a common difference of -1 and a first term of 239. Using the formula for the sum of an arithmetic series, we get:

S = n/2 * (first term + last term)

S = 240/2 * (239 + 1)

S = 240/2 * 240

S = 28,800

Therefore, there were 28,800 handshakes that occurred at the meeting.

It's worth noting that this calculation assumes that each handshake is counted twice (once for each person involved). If we only counted each handshake once, then we would need to divide our final answer by 2, giving us 14,400 handshakes.

Answer:g maybe

Step-by-step explanation:

I choose City Bus as mode of transport since from function rule it is clear that the per mile cost for City Bus is lesser than any other transportation.

Option 1: Let the model for Taxi be f(x) = ax + b, where f(x) is total cost and x is number of miles.

From the table of Taxi we get, f(3) = 26.95; f(6) = 28.90; f(9) = 30.85 and f(12) = 32.80.

So, 3a + b = 26.95 and 6a + b = 28.90

So, (6a + b) - (3a + b) = 28.90 - 26.95

3a = 1.95

a = 1.95/3 = 0.65

Now, f(9) = 30.85

9*0.65 + b = 30.85

5.85 + b = 30.85

b = 30.85 - 5.85 = 25

So the model is, f(x) = 0.65x + 25

Option 2: Let the model for City Bus be f(x) = cx + d, where f(x) is total cost and x is number of miles.

From the table of Taxi we get, f(2) = 0.60; f(4) = 1.20; f(6) = 1.80 and f(8) = 2.40.

So, 2a + b = 0.60 and 4a + b = 1.20

(4a + b) - (2a + b) = 1.20 - 0.60

2a = 0.60

a = 0.60/2 = 0.30

Now, f(8) = 2.40

8*0.30 + b = 2.40

2.40 + b = 2.40

b = 2.40 - 2.40 = 0

So the function rule for City Bus is, f(x) = 0.3x.

Option 3: From the graph of Light Rail we can see that for any distance travelled total cost remains same that is 15.

So the function rule for Light Rail will be a constant function is, f(x) = 15

Option 4: Let the model for Motorized Scooter be f(x) = mx + n, where f(x) is total cost and x is number of miles.

From the graph we can see that, f(0) = 5, f(1) = 6, f(3) = 8 etc.

So, n = 5

and m + n = 6

m + 5 = 6

m = 6 - 5 = 1

Hence the function rule for Motorized Scooter is, f(x) = x + 5.

Hence I choose City Bus as mode of transportation as the per mile cost for that transportation mode is less than any other.

The specific numerical solution will depend on the number of firms in the market and their behavior.

In a Stackelberg version of monopolistic competition, there is a leader firm that sets its output first, and all the other firms in the market act as followers and choose their outputs simultaneously.

Suppose there are "n" firms in the market, with the first firm denoted as the leader. Let's assume that each firm has a constant marginal cost of $10 per unit. Then, the leader firm's profit-maximizing output level can be found by solving the following problem:

max (30-Q1-Q2-...-Qn)Q1 - 10Q1

subject to Q1 >= 0

where Q1 is the output level of the leader firm, and Q2, Q3, ..., Qn are the output levels of the follower firms.

Taking the first-order condition by differentiating with respect to Q1 and setting it equal to zero, we get:

d/dQ1 [(30-Q1-Q2-...-Qn)Q1 - 10Q1] = 0

Simplifying this expression, we get:

30 - Q1 - Q2 - ... - Qn - 2Q1 = 0

Solving for Q1, we get:

Q1 = (30 - Q2 - ... - Qn)/3

This equation gives us the leader firm's profit-maximizing output level as a function of the follower firms' output levels.

Now, let's consider the follower firms' profit-maximizing output levels. Since each follower firm is a price-taker, its profit-maximizing output level can be found by equating marginal cost to market price, which is equal to the market demand curve divided by the total quantity produced by all firms in the market. Therefore, the profit-maximizing output level of the jth follower firm can be expressed as:

Qj* = (1/n) * (30 - Q1 - Q2 - ... - Qj-1 - Qj+1 - ... - Qn - 10)

where Qj* is the follower firm's profit-maximizing output level, and j = 2, 3, ..., n.

Using these expressions for the leader and follower firms' profit-maximizing output levels, we can solve for the equilibrium outputs and profits in the Stackelberg version of monopolistic competition. However, the specific numerical solution will depend on the number of firms in the market and their behavior.

Answer: 6 units

Step-by-step explanation:

The formula for the volume of a cylinder is V = πr²h, where V is the volume, r is the radius, and h is the height.

In this case, we know that the radius (r) of the cylinder is 5, and the volume (V) is 150π. Substituting these values into the formula, we get:

150π = π(5²)h

Simplifying the equation, we get:

150 = 25h

Dividing both sides by 25, we get:

h = 6

Therefore, the height of the cylinder is 6 units.
