[tex]\boxed{y = -\dfrac{10}{3}x - 23}[/tex]

Step-by-step explanation:

Equation of a straight line: y = kx + b

Points: (-9,7) and (-6,-3)

Сompose the system of equations:

[tex]\displaystyle \left \{ {{7=-9k + b} \atop {-3=-6k + b}} \right[/tex] [tex]\displaystyle \left \{ {{b= 7 + 9k} \atop {b=6k - 3}} \right \Longrightarrow 7 + 9k = 6k - 3[/tex]

[tex]7 + 9k = 6k - 3[/tex]

[tex]3k = -10|:3[/tex]

During a thunder storm, the amount of rain on the ground increased at an average rate of 0.25 inch per hour. There was already 4.5 inches of rain on the ground when the storm started. Write an equation that can be used to determine the total amount of rain on the ground (T), in inches, after h hours of the storm.

Answers

4.5 + 0.25T

Explanation: 4.5 inches of rain already exist on the ground and 0.25 inches are being added every hour. And since the amount of hours are “T”, the amount of rain after T hours will be 0.25T

What is the equation of the line shown in the graph?

Answers

Answer:

y = -1x -2

Step-by-step explanation:

[] First, we can tell it is negative because it is going from top-left to bottom-right

[] Next, it intercepts the y-axis at -2, so our b is -2

[] Last, since it is graphed, we can use "rise over run"

       () We move down one and to the right one, this becomes 1/1, which becomes a slope of 1, so our m is -1 since it is negative

Now let's plug our pieces in

Slope-intercept form is y = mx + b

y = mx + b

y = (-1)x + b

y = -1x -2

Mr. Murphy is designing a rectangular concrete fire pit. The concrete sides and bottom will be 5 inches thick. The interior length will be 3 times the interior
height and the interior width will be 2 times the interior height. What should the outer dimensions of the fire pit be if the inner volume is to be 6000 cubic
inches?
Enter the correct values in the boxes.

*15 is correct but 25 & 35 are wrong ..*

Answers

For the outer dimensions: length = 35 inches, width = 25 inches, and height = 15 inches.

Step-by-step explanation:

For the interior;

volume = 6000

length, l = 3h

width, w = 2h

height = h

But,

Volume of a cuboid = length x width x height

So that;

6000 = 3h x 2h x h

6000 = 6

Divide through by 6 to have;

1000 =

h =

 = 10

Thus, the height is 10 inches. Thus;

length, l = 3h = 3 x 10 = 30 inches

width, w = 2h = 2 x 10 = 20 inches

For the outer dimension, since the concrete sides and bottom would be 5 inches thick. Then its dimension are;

length, l = 30 + 5 = 35 inches

width, w = 20 + 5 = 25 inches

height = 10 + 5 = 15 inches

Can you find x for me?

Answers

180 - 110 = 70

70 - 30 = 40

40 / 8 = 5

x = 5

Answer:
x = 10

Explanation:
So, from the two arches in the angles were can infer that those two angles are congruent. That means that 110 equals 8x+30. So to solve this here’s the process:
110=8x+30 (set up the equation)
80=8x (subtract 30 from both sides)
x=10 (divide by 8 on both sides)

Please Help me i need help Pleaaaasssseeeee im not good at numbers ._. Find the equation of the line that passes through the point (2,-6) and is perpendicular to the line y=1/4x-2.

Answers

Answer:

y = -4x + 2

Step-by-step explanation:

1) Find perpendicular slope

1/4 = -4

2) Plug in x and y

y = -4x + b

((((( y = -6, x = 2 ))))))

-6 = -4(2) +b

-6 = -8 + b

2 = b

3) Return to equation but plug in b, but not x and y

y = -4x + 2
