The temperature was 45 degrees at 6am and and 70 degrees at noon. Identify the rate of change and explain what it means in this situation

A perpendicular line has the negative reciprocal slope of the given line.

The slope of the given line is x/2, which can be written as 1/2x

The negative reciprocal of 1/2 would be -2

The equation for a line is written as y = mx +b, where m is the slope and b is the y-intercept.

We already have the slope ( -2)

So we can solve for b by replacing y x and m with the slope and the point given:

8 = -2(1) +b

8 = -2 + b

b = 10

The equation would be y = -2x + 10

most likely it would be less than

3+4+5.

You could split it into different groups because of the communative property.

These are two combonations. :) (I'll put 3 so you can chose)

3 + 4 = 7 + 5 = 12.

3 + 7 = 10 + 4 = 14

7 + 4 = 11 + 3 = 14

The formula of a midpoint:

[tex]M_{ST}\left(\dfrac{x_S+x_T}{2},\ \dfrac{y_S+y_T}{2}\right)[/tex]

We have:

[tex]M(5,\ -8)\to x_M=5,\ y_M=-8\\T(4,\ -6)\to x_T=4,\ y_T=-6[/tex]

Substitute:

[tex]\dfrac{x_S+4}{2}=5\qquad|\cdot2\\\\x_S+4=10\qquad|-4\\\\x_S=6\\\\\dfrac{y_S+(-6)}{2}=-8\qquad|\cdot2\\\\y_S-6=-16\qquad|+6\\\\y_S=-10[/tex]

Answer: 75 customers

Step-by-step explanation:

hey! so for this question you have to cross multiply and divide.

1/12 = 900/1 so 1 times 900 is 900 then divide that by 12 which is 75.

The Answer is: -116

(sorry I'm 3 years late...)

Step-by-step explanation:

Speed = Distance /  time:

Speed = 825 miles / 17 hours

Speed = 48.529 miles per hour. (Round the answer as needed).

Gas mileage = miles traveled  / gallons used

Gas mileage = 825 miles / 38 gallons = 21.71 miles per gallon (Round answer as needed).

Unit rate of gas = Total money spend /  gallons bought:

Unit rate of gas = $125 / 38 gallons = $3.289 per gallon.

Answer:

[tex]Speed = 48.53mph[/tex]

[tex]Gas.Mileage = 27.7 mpg[/tex]

[tex]Unit.Price = 3.29/gallon[/tex]

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

In order to find the Speed we need to divide the amount of total miles in the trip to California by the amount of time that it took.

[tex]Speed = \frac{Miles}{Hours}[/tex]

[tex]Speed = \frac{825.miles}{17.hours}[/tex]

[tex]Speed = 48.53mph[/tex]

Next we can calculate the Gas Mileage by dividing the amount of total miles  by the amount of gallons of gas that the trip wasted.

[tex]Gas.Mileage = \frac{Miles}{Gallon}[/tex]

[tex]Gas.Mileage = \frac{825.miles}{38.gallons}[/tex]

[tex]Gas.Mileage = 27.7 mpg[/tex]

Finally, we can calculate the Unit Price by dividing the total amount of money wasted in the trip by the amount of gallons used in that trip.

[tex]Unit.Price = \frac{Total}{Gallons}[/tex]

[tex]Unit.Price = \frac{125}{38.gallons}[/tex]

[tex]Unit.Price = 3.29/gallon[/tex]

Okay for this problem you can multiply 6 by 4.5 aand get 27 as your answer.

So 6×4.5=27 miles in 4.5 hours

We need to graph a function and use that graph to estimate how many miles lava moves in 4.5 hours.

The graph and estimations can be seen at the end of the answer.

Let's see how to graph this:

We know that the function is y= 6*x

What we need to do, is find two points in the that belong to the line, to get that, we need to evaluate the function in two points:

if x = 0:

y = 6*0 = 0

Then we have the point (0, 0)

if x = 1:

y = 6*1 = 6

Then we have the point (1, 6)

Now to graph the function, we just need to find these two points and draw a line that connects them.

A graph is shown at the end of the answer.

To estimate the distance that the lava has moved in 4.5 hours, we need to find the value 4.5 in the x-axis, then we draw a vertical line that passes through there.

In the point where this vertical line intersects the graph, we draw a horizontal line.

That horizontal line will intersect the y-axis in the correspondent y-value to x = 4.5

An example of this can be seen in the image below, my estimation is that the lava has moved something near 26 miles.

Answer: [tex]y=1.6x+6.8[/tex]

Step-by-step explanation:

1. The equation of a regression line has the following form:

[tex]y=mx+b[/tex]

Where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.

2. You need to calculate the slope with the points given in the exercise:

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

3. Substitute values:

[tex]m=\frac{18-10}{7-2}[/tex]

[tex]m=\frac{8}{5}=1.6[/tex]

4. Now, you must calculate [tex]b[/tex]:

-Substitute the value of the slope into the equation above.

- Take one of the given points and substitute them into the equation.

Then:

[tex]y=mx+b\\10=(1.6)(2)+b\\b=10-3.2\\b=6.8[/tex]

5. Therefore, the equation is:

[tex]y=1.6x+6.8[/tex]

20x

in mathematics ' product ' means multiply

4 × 5x = 20x

Answer:

In 5 weeks they will have the same amount.

Step-by-step explanation:

1. You have that Tyronne has $60, she gets $5 each week and also gets an additional $10 each week. She saves her money. Therefore, you can write the following expression:

[tex]60+5x+10x\\60+15x[/tex]

Where [tex]x[/tex] is the number of weeks.

2. Her sister has $135, she gets $5 each week and also gets an additional $10 each week, but she spends this money. Therefore:

[tex]135+5x+10x-5x-10x\\135[/tex]

3. If this amounts of money will be equal, you have:

[tex]60+15x=135\\15x=75\\x=5[/tex]

4. Therefore, in 5 weeks they will have the same amount.

(a)

Let's assume

y is total cost

x is number of ride tickets

(b)

Since, this is linear relationship

so, we can assume equation as

[tex]y=mx+b[/tex]

The Fall Festival charges $0.75 per ticket for the rides

so,

[tex]m=0.75[/tex]

we can plug it

[tex]y=0.75x+b[/tex]

Kendall bought 18 tickets for rides and spent a total of $33.50 at the festival

so, we have

at x=18 , y=33.50

we can use it to find b

[tex]33.5=0.75*18+b[/tex]

now, we can solve for b

[tex]b=20[/tex]

we can plug it back

and we get

[tex]y=0.75x+20[/tex]

(c)

we got

[tex]y=0.75x+20[/tex]

here ,

y is the cost for anyone who only pays for festival admission and rides

x is number of admission

so, our equation will give total cost

To determine if it’s a right triangle you would use the Pythagorean theorem. A^2+B^2=C^2 <——- That’s the equation. So you have to know that the hypotenuse(c) is always the longest side. 28^2+45^2=53^2. So yes it is a right triangle.

The  equation of the circle shown in the graph will be (x - 3)² + (y)² = 4

The standard equation of a circle is given as:

(x - a)² + (y- b)² = r²

where:

(a, b) is the centre

r is the radius of the circle

Assume the centre of the circle is (3, 0) and the radius of 2

Substitute to have:

(x - 3)² + (y-0)² = 2²

(x - 3)² + (y)² = 4

Hence the  equation of the circle shown in the graph will be (x - 3)² + (y)² = 4

To solve this we must isolate x which involves having the variables on one side and the numbers on the other.

First add 2m to both sides

3m+7/2=-2m+5/2

5m+7/2=5/2

Then we subtract 7/2 from both sides

5m+7/2=5/2

5m=-1

Finally we divide both sides by 5

5m/5=-1/5

Our final answer is -1/5

So the answer is B

Answer:

The artist's earnings for the CD will be $168000.

Step-by-step explanation:

The total sales amount is $2500000

The artist receives a royalty payment of 7%. So, the amount of royalty, the artist receives will be:  [tex](\$2500000\times 7\%)= (\$2500000\times 0.07)=\$175000[/tex]

The agent gets 4% of what the recording artist gets. So, the amount of money the agent gets will be:  [tex](\$175000\times 4\%)=(\$175000\times 0.04)=\$7000[/tex]

So, the artist’s earnings for the CD will be:  [tex](\$175000-\$7000)= \$168000[/tex]

The modified recipe will make a total of 10 servings.

Since Marcus is using 5 eggs in the modified recipe instead of 3, we can calculate the ratio as follows:

Ratio = (Number of eggs in modified recipe) / (Number of eggs in original recipe)

Ratio = 5 eggs / 3 eggs

Next, we need to apply this ratio to the number of servings in the original recipe. Since all other ingredients are being increased proportionally, the number of servings will change accordingly.

Total Servings in Modified Recipe = (Number of servings in original recipe) * Ratio

Given that the original recipe makes 6 servings, we can substitute the values:

Total Servings in Modified Recipe = 6 servings * (5 eggs / 3 eggs)

Total Servings in Modified Recipe = 6 * (5/3)

Total Servings in Modified Recipe = 10

Therefore, the modified recipe will make a total of 10 servings.
