Answer:
y = -11x - 13
Step-by-step explanation:
Step 1: Subtract 11x from both sides.
[tex]11x+y-11x=-13-11x[/tex] [tex]y=-11x-13[/tex]Therefore, the answer is y = -11x - 13.

The rate of change or essentially the slope is a numerical value that describes the direction and the steepness of the line.
To find the slope, we just need any two points on the line
--> Let's pick (0,2) and (2,6)
The slope's equation = [tex]\frac{y2-y1}{x2-x1}[/tex]
Let's plug the known quantities into the equation
[tex]\frac{y2-y1}{x2-x1}=\frac{6-2}{2-0} =\frac{4}{2} =2[/tex]
Therefore the rate of change is 2 km/trip
Hope that helps!

A man paid a debt of $6789 in three payments. The second time he paid $3 more than he did the first time and the third payment was twice as much as the second payment. What was the amount of each payment?
Answer:
$6789.00, $20,367.00, $40,734.00
Step-by-step explanation:
debt: $6,789.00
multiply by $3 which equals $20,367.00
then take the value of $20,367.00 and multiply again by 2 which equals 40,734.00
that's my step by step explanation

Answer for 20 points
The volume of the rectangular prisms is given by 72 in³, 36 in³, 80 in³ and 54 in³
What is volume?
Volume is the amount of space occupied by a three dimensional shape or object.
The volume of a rectangular prism is given by:
Volume = length * width * height
a) Dimensions: 4 in., 3 in., 6 in.
Volume = 4 * 3 * 6 = 72 in³
b) Dimensions: 6 in., 3 in., 2 in.
Volume = 6 * 3 * 2 = 36 in³
c) Dimensions: 4 in., 5 in., 4 in.
Volume = 4 * 5 * 4 = 80 in³
d) Dimensions: 2 in., 9 in., 3 in.
Volume = 2 * 9 * 3 = 54 in³
The volume of the rectangular prisms is given by 72 in³, 36 in³, 80 in³ and 54 in³

bill can mow a lawn in 40min and jhon can mow for 60min.how long will it take to mow together
24 minutes.
Let me explain.
The lawn can be any size, but for the purpose of simplicity, let's say it's 240 square meters.
Peter mows 6 square meters per minute if he mows 240 square meters in 40 minutes.
John mows 4 square metres each minute if he mows 240 square metres in 60 minutes.
They'll mow 10 square meters per minute if they work together.
As a result, mowing the entire lawn will take them 24 minutes.
(Note that the location is irrelevant as long as we know how long each man takes to complete the task separately.) The answer would be the same if the field was 1 million hectares in size.)
I hope this helps.

In this part we will just focus on Semicircle with diameter 22 ft.
Given :-
Diameter = 22 ft[tex] \\ [/tex]
To find:-
Area of semicircle[tex] \\ [/tex]
So first of all let's convert diameter into radius.
we know:-
[tex] \boxed{ \rm{}radius = \frac{Diameter}{2} }[/tex]
So:-
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{Diameter}{2} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{22}{2} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{2 \times 11}{2} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{\cancel2 \times 11}{\cancel2} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{11}{1} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = 11[/tex]
[tex] \\ \\ [/tex]
Now let's find area of semicircle!
We know:-
[tex] \boxed{ \rm Area~of~semicircle = \frac{\pi {r}^{2} }{2} }[/tex]
[tex] \\ [/tex]
so:-
[tex] \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _1= \dfrac{\pi {r}^{2} }{2} [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _1= \dfrac{22 \times {11}^{2} }{7 \times 2} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _1= \dfrac{\cancel{22} \times {11}^{\cancel2} }{7 \times \cancel2} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _1= \dfrac{11\times {11}^{\cancel2} }{7} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _1= \dfrac{1331}{7} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\bf Area~of~semicircle _1= 190.14 \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \gray{ \bf \dag \frak{Part 2}}[/tex]
So in this part we will find area of other semicircle.
Now as u can see BC isn't given , but AC and AB are given.
So let's find BC:-
AC = AB + BCBC = AC - ABBC = 30 - 22BC = 8 ft[tex] \\ [/tex]
Now we got the diameter, so let's change it into radius.
we know:-
[tex] \boxed{ \rm{}radius = \frac{Diameter}{2} }[/tex]
[tex] \\ [/tex]
so :-
[tex] \hookrightarrow\sf{}radius = \dfrac{Diameter}{2} [/tex]
[tex] \\[/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{8}{2} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{2 \times 4}{2} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{\cancel2 \times 4}{\cancel2} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = 4[/tex]
[tex] \\ [/tex]
Now let's find area of semicircle!
We know:-
[tex] \boxed{ \rm Area~of~semicircle = \frac{\pi {r}^{2} }{2} }[/tex]
[tex] \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{\pi {r}^{2} }{2} [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{22 \times {4}^{2} }{7 \times 2} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{\cancel{22} \times {4}^{\cancel2} }{7 \times \cancel2} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{11\times {4}^{2} }{7} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{11\times 16}{7} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{176}{7} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\bf Area~of~semicircle _2= 25.14 \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \gray{ \bf \dag \frak{Part 3}}[/tex]
Now Finally in this part we'll add both the areas of these semicircles.
Let :-
Area of semicircle with diameter AB be A₁Area of semicircle with diameter BC be A₂[tex] \\ \\ [/tex]
[tex] \sf: \implies Area~of~figure=A_1+A_2 \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \sf: \implies Area~of~figure=190.14+25.14 \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \bf: \implies Area~of~figure=215.28 {ft}^{2} \\ [/tex]
[tex] \\ \\ [/tex]
Explain How you get -8 whe solving -5+-3
Answer:
-5+(-3)
=-5-3
=-8
Step-by-step explanation:In a problem like this you have to write -3 in parentheses.
Since the + sign is outside the parentheses here, the -3 and + sign are multiplied.
+ saha- multiplication yields -sign.
So there's a -3 coming.
Then -5-3.
Since the sign of this is the same, the two numbers are added. In both - the mark is applied to the answer because there is a mark.

The function represent the quadratic function is h(x) = 3x(x – 2) – 4, the correct option is D.
What is Quadratic funtion?
Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax^2 + bx + c where a, b, c, ∈ R and a ≠ 0.
The function which represnt a quadratic function is;
[tex]\rm h(x) = 3x(x - 2) - 4\\\\ h(x)=3x\times x - 3x \times 2-4\\\\ h(x)=3x^2-6x-4[/tex]
The highest degree of the function is 2 so the function is the quadraic function.
Hence, the function represent the quadratic function is h(x) = 3x(x – 2) – 4.

Answer:
y = -1/5x + 6.4
Step-by-step explanation:
Use the point-slope formula.
y-y₁ = m(x -x₁)
so...
y-7 = -1/5(x - (-3))
y = -1/5x+ 32/5

Answer:
to find the volume of a cylinder formulae is pi r² x Height
Step-by-step explanation:
because to find the volume of any object we have to multiply the area of the base and the height
now as the base of the cylinder is circle we have to fulfill the area of circle with the height of the cylinder
hence
volume
of
the
cylinder = area of circle x height
= pi r² x Height
