Answer:

m = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, - 1 ) and (x₂, y₂ ) = (3, 8 )

m = [tex]\frac{8-(-1)}{3-(-3)}[/tex] = [tex]\frac{8+1}{3+3}[/tex] = [tex]\frac{9}{6}[/tex] = [tex]\frac{3}{2}[/tex]

Answer:

3/2

Step-by-step explanation:

To find the slope, we use the slope formula

m = ( y2-y1)/(x2-x1)

    = (8- -1)/( 3 - -3)

    = (8+1)/(3+3)

     = 9/6

    = 3/2

The required, -x is also 13 units from 0, but to the right of 0 instead of to the left.

The statement about -x is that it is 13 units to the right of 0. This is because the original number, which is 13 units to the left of 0, is represented by a point on the number line to the left of 0. If we negate this number to get -x, then we are reflecting it across the origin (0) to the right side of the number line. This means that the distance of -x from 0 is the same as the distance of the original number from 0, which is 13 units.

Therefore, -x is also 13 units from 0, but to the right of 0 instead of to the left.

Answer:

To rotate a point 90 degrees clockwise about another point, you can follow these steps:

1. Subtract the coordinates of the center of rotation from the coordinates of the point you want to rotate to translate the center of rotation to the origin.

A translated point A would be: (5 - 0, 4 - 1) = (5, 3)

2. Perform the rotation by swapping the x and y coordinates and negating the new x-coordinate.

The rotated point A' would be: (3, -5)

3. Add the coordinates of the original center of rotation to the rotated coordinates to translate the origin back to the center of rotation.

The final coordinates of point A' would be: (3 + 0, -5 + 1) = (3, -4)

The length of the remaining rope is 166/63 meters, or approximately 2.635 meters when rounded to three Decimal places.

To find the length of the remaining rope, we need to subtract the sum of the lengths of the two pieces that were cut from the original length of the rope.

Original length of the rope = 8 m

Length of the first piece cut = 15/7 m

Length of the second piece cut = 29/9 m

Therefore, the length of the remaining rope can be found as:

Remaining length = Original length - Length of first piece - Length of second piece

Remaining length = 8 - 15/7 - 29/9

To perform the subtraction, we need to find a common denominator for 7 and 9, which is 63.

Remaining length = 504/63 - 135/63 - 203/63

Remaining length = (504 - 135 - 203)/63

Remaining length = 166/63

To simplify the fraction, we can divide both the numerator and denominator by their greatest common factor, which is 1.

Remaining length = 166/63 meters

Therefore, the length of the remaining rope is 166/63 meters, or approximately 2.635 meters when rounded to three decimal places.

The hotel charge in the first city before tax was $6000 and the hotel charge in the second city before tax was $7500.

Let x be the hotel charge before tax in the first city, and y be the hotel charge before tax in the second city. Then we have:
y = x + 1500   (the hotel charge before tax in the second city was $1500 higher than in the first)
0.075x + 0.05y = 825   (the total hotel tax paid for the two cities was $825)
We can use the first equation to solve for y in terms of x:
y = x + 1500
Then we can substitute this expression for y into the second equation:
0.075x + 0.05(x + 1500) = 825
Simplifying this equation, we get:
0.075x + 0.05x + 75 = 825
0.125x = 750
x = 6000
So the hotel charge before tax in the first city was $6000. Using the first equation, we can find the hotel charge before tax in the second city:
y = x + 1500
y = 6000 + 1500
y = 7500
So the hotel charge before tax in the second city was $7500.
Therefore, the answer is: The hotel charge in the first city before tax was $6000 and the hotel charge in the second city before tax was $7500.

Answer: 40 cups per min = 2.5 gallons per hour

Step-by-step explanation:

The value of x that satisfies the equation -1.5x - 2.7 = 20.1 + 4.5x is -3.8.

To solve this equation, we need to isolate the variable x on one side of the equation. We can do this by using basic algebraic operations, such as adding, subtracting, multiplying or dividing both sides of the equation by the same value.

The first step in solving this equation is to get rid of the constant terms on one side of the equation. We can do this by adding 2.7 to both sides of the equation:

-1.5x - 2.7 + 2.7 = 20.1 + 4.5x + 2.7

Simplifying the left-hand side of the equation, we get:

-1.5x = 20.1 + 4.5x + 2.7

Next, we can move the variable terms to the left side of the equation and the constant terms to the right side of the equation by subtracting 4.5x from both sides:

-1.5x - 4.5x = 20.1 + 2.7

Simplifying the left-hand side, we get:

-6x = 22.8

Finally, we can solve for x by dividing both sides of the equation by -6:

x = -3.8

Therefore, the value of x that satisfies the equation -1.5x - 2.7 = 20.1 + 4.5x is -3.8.

Miles is the number of miles Martin has run, and Total Time is the total time in minutes that he has been running, which is 11Miles + 5.

To create a linear model, we need to find the equation of the line that best fits the data.

We can do this by finding the slope and y-intercept of the line.
First, we need to find the slope, which is the change in y divided by the change in x.

We can choose any two points on the line to calculate the slope.

Let's use the first and second data points:
Slope = (y2 - y1) / (x2 - x1)
Slope = (104 - 60) / (9 - 5)
Slope = 44 / 4
Slope = 11
Now we can use the point-slope form of the equation of a line to find the y-intercept.

We can use the first data point:
The linear model has the form y = mx + b, where y represents the total time (in minutes), x represents the miles run, m is the slope, and b is the y-intercept.

We can use the data points to find the slope (m) as follows: m = (change in total time) / (change in miles)

Using the first two data points, (5, 60) and (9, 104):

m = (104 - 60) / (9 - 5) = 44 / 4 = 11

Now that we have the slope, we can find the y-intercept (b) using one of the data points.

Let's use (5, 60): 60 = 11 * 5 + b 60 = 55 + b b = 5

So the linear model representing Martin's pace is: y = 11x + 5 In this model, x is the miles run, and y is the total time in minutes.
y - y1 = m(x - x1)
y - 60 = 11(x - 5)
y - 60 = 11x - 55
y = 11x + 5
So the linear model that shows the miles Martin has run as the input, and the total time, in minutes, he has been running as the output is
Total Time = 11Miles + 5

Tickets Sold: 146

Step-by-step explanation:

Let's assume that the number of adult tickets sold is "x".

According to the problem, the number of student tickets sold is three times the number of adult tickets sold. Therefore, the number of student tickets sold is 3x.

The total number of tickets sold is 584, so we can set up an equation:

x + 3x = 584

Simplifying the equation, we get:

4x = 584

Dividing both sides by 4, we get:

x = 146

Therefore, the number of adult tickets sold is 146.

Answer: 146

Step-by-step explanation:

let x = # of adult tickets sold

let y = # of student tickets sold

x + y = 584

this is because the sum of adult tickets and student tickets is 584.

3x = y

this equation is written because there is 3 times more students there than adults

using substitution, we can find the equation :

x + (3x) = 584

4x = 584

x = 146

since x is equal to the number of adult tickets sold, your answer is 146.

We first graph the line 2x - 3y = 12:

To graph the line, we can find the x and y intercepts:

When x = 0, we have -3y = 12, then y = -4, so (0, -4) is a point on the line.

When y = 0, we have 2x = 12, then x = 6, so (6, 0) is a point on the line.

Plot these two points and draw the line passing through them:

Next, we shade the region that satisfies the inequality 2x - 3y < 12:

We can choose a test point not on the line, such as (0,0).

Substitute the coordinates into the inequality:

17.55% is the probability for any day, the number of special orders sent out will be exactly 5

The given situation describes a Poisson distribution with a mean of 5 special orders per day. The probability of getting exactly 5 special orders in a day can be calculated using the Poisson probability formula, which is:

P(X = k) = (e^(-λ) * λ^k) / k!

where X is the random variable representing the number of special orders, λ is the mean number of special orders per day, and k is the number of special orders we want to find the probability for.

Plugging in the given values, we get:

P(X = 5) = (e^(-5) * 5^5) / 5!

Simplifying this expression, we get:

P(X = 5) = 0.1755

Therefore, the probability of getting exactly 5 special orders in a day is 0.1755 or 17.55%, rounded to four decimal places.

Intuitively, this means that out of many days, we can expect around 17.55% of them to have exactly 5 special orders sent out. The Poisson distribution is commonly used to model the number of events occurring in a fixed period of time, given a known average rate of occurrence.
