Answer:

p = 6

Step-by-step explanation:

The slope equation is:

[tex]m = \frac{y \frac{}{2} - y \frac{}{1} }{x \frac{}{2} - x \frac{}{1} } [/tex]

then to know the value of "p":

[tex] - \frac{1}{3} = \frac{7 - p}{p - 9} \\ - 1(p - 9) = 3(7 - p) \\ - p + 9 = 21 - 3p \\ 3p - p = 21 - 9 \\ 2p = 12 \\ p = \frac{12}{2} \\ p = 6[/tex]

Composition of functions~

Answers

Answer:

option D

Step-by-step explanation:

First you must find g(n) given that n is -3n:

g(-3n) = -3n - 1

Then plug that in f(n) as the new n:

f(n) 3( -3n - 1) + 5

= -9n -3 + 5

= -9n + 2

So option D

Complete the table using equivalent ratios.

Number of trees Number of cabins

10.5 5
__ 3

Answer:

for seven cabins it should be 14.7 trees, im not sure about 3 cabins, sorry :(

Answer:

3) 6.3

7) 14.7

Step-by-step explanation:

Use ratios to solve the table

10.5/5 = x/3

cross multiply

31.5 = 5x

x = 6.3

10.5/5 = x/7

73.5 = 5x

x = 14.7

Step-by-step explanation:

Tyler says he invented a number puzzle.



He asks Clare to pick a number, and then asks her to do the following:



Triple the number



Subtract 7

Double the result



Subtract 22



Divide by 6



Clare says her final answer is -3. Tyler says her original number she thought must have been 3.



How did Tyler know that? Explain or show your reasoning.

Answers

If Clare’s original number was 3 then she would first triple the number
3*3 is 9
Subtract 7 from 9 and you get 2
2 doubled is 4
22 subtracted from 4 is -18
-18 divided by 6 is -3
So Tyler just took Clare’s final answer (-3) and did the opposite if the steps back words
(multiple by 6, add 22, divide by 2, add 7, divide by 3)

Q: Water is drained out of tank, shaped as an inverted right circular cone that has a radius of 6cm and a height of 12cm, at the rate of 3 cm3/min. At what rate is the depth of the water changing at the instant when the water in the tank is 9 cm deep? Give an exact answer showing all work and include units in your answer. Show your work

Answers

h = 9 cm
r = (6/12)9 = 4.5 cm

dV = pi r^2 dh
so
dV/dt = pi r^2 dh/dt

-3 cm^3/min = pi (4.5)^2 dh/dt
so
dh/dt = -3/[ pi(4.5)^2]
about .047 cm/min

Does the system have no solution?​

Answers

Answer:

[tex]\mathrm{A)\:}-6[/tex]

Step-by-step explanation:

Notice that in the second equation, the coefficient of [tex]y[/tex] is [tex]2[/tex] times greater than in the first. Therefore, by making the coefficient of [tex]x[/tex] in the second equation [tex]2[/tex] times greater than in the first, it's impossible to only isolate one variable.

Therefore, when [tex]a=-3\cdot 2=\fbox{-6}[/tex], there are no solutions to this system.

write an equation of the line in a slope intercept form of a line that passes through (5,7) and (4,4)

Answers

Answer:

y = 3x - 8

Step-by-step explanation:

passes through (5, 7) and (4, 4)

Find slope:

(7 - 4) / (5 - 4)

= 3/1

= 3

This is your slope.

Now plug in a set of coordinates.

y = 3x + b

7 = 3(5) + b

7 = 15 + b

b = -8

Your equation is: y = 3x - 8

Check your work by plugging in the second coordinate pair.

y = 3x - 8

4 = 3(4) - 8

4 = 12 - 8

4 = 4

Your solution is correct.

Find the slope of the line passing through points -2, 2 and 2, 0

Answers

Explanation

We can find the slope by using the slope formula. Also know rise over run.

[tex] \large \bold{m = \frac{rise}{run} }[/tex]

[tex]m = \frac{2 - 0}{ - 2 - 2} \\ m = \frac{2}{ - 4} \\ m = - \frac{1}{2} [/tex]

From the slope-intercept y = mx+b.

[tex] \large \bold {m = slope } \\ \large \bold {b = y - intercept }[/tex]

Answer

[tex] \large \boxed { - \frac{1}{2} }[/tex]

Answer:

-1/2

Step-by-step explanation:

Going from (-2, 2) to (2, 0), x (the run) increases by 4 and y (the rise) decreases by 2.  Thus, the slope of this line is m = rise / run = -2/4 = -1/2.

An online clothing company sells custom sweatshirts. The company charges
$5.50 for shipping plus $8.00 for each sweatshirt. Write a linear function rule that models the total
costy (in dollars) for any number of sweatshirts x

Answers

Well, the equation for this problem is 5.50x + 8.00.
The y-intercept / initial value in the problem is $5.50 because that is what you have to pay and it’s basically your initial value whereas $8.00 is your slope or rate if change because that is why you have $8.00x which means that whatever number of sweatshirts you buy, they will each cost you $8.00.

Just answer the question if you actually answer it you get brainliest and 50 points.

Answers

Step-by-step explanation:

f(x) = a * b^x

We have the following information:

f(0) = a * b^(0) = 15. => a * 1 = 15, a = 15.

f(1) = a * b^(1) = 9. => a * b = 9, (15) * b = 9, b = 0.6.

Hence f(x) = 15 * 0.6^x.

A rectangular prism measures 7 & 1/2 cm by 12 cm by 15 & 1/2 cm. Calculate the number of cubes with edge length 1/2 cm that fit in this prism.

Answers

Answer: 8 cubes

Step-by-step explanation:

Volume of a rectangular prism is length × height × width

Length=7 1/2

Width= 15 1/2

Height=12

Volume of the prism is therefore:

7 1/2×12×15 1/2= 1395cm3

No of cubes with edge length 1/2 to fit into the prism will be:

Volume of cube is L*W*H

1/2*1/2*1/2= 1/8cm3

Therefore the no of cubes to fit into the Prism will be:

1395/(1/8)= 11160 cubes.

If one was stuck,the number of 1/2 edge length

cube to fit into 1cm will be:

1/(1/8)= 8 cubes
