Explanation:
We can pick any (x,y) point on this blue line as long as we don't pick (0,0)
This is because we cannot divide by zero.
Let's say we pick the point (x,y) = (1,4)
The constant of proportionality is found like so
k = y/x
k = 4/1
k = 4
The constant of proportionality is 4
Or we could pick a point like (2,8) to get
k = y/x
k = 8/2
k = 4
We get the same thing.
There are infinitely many points to pick, but in my opinion, it's easiest to stick with (1,4).
As a slight alternative, you can apply the slope formula (pick any two points you want on the blue line) and you should get 4 as well.
-----------------
Extra info:
The direct proportion equation always goes through the origin. This means the y intercept is 0. The slope is equal to the constant of proportionality. The equation of this line is y = 4xAnswer:
y/x = 4Step-by-step explanation:
For any point from line for 1 of x we have 4 ys:
x=1→y=4, x=2→y=8=4×2, x=7→y=28=4×7
It means:
y = 4x dividing by x we get: y/x = 4

- 33 - 6a = - 5(4a - 3)
could I please get some help
Answer:
can I get a better explanation and I'll help
Answer:
Step-by-step explanation:
first distribute -5(4a-3) to get -20a +15
second -33-6a=-20a+15 and add 20 to both sides to get -33+14a=15
third add 33 to both sides to get 14a=48
fourth divide 14 on both sides to get a = 3.43 (rounded to nearest hundredth)

Roberto is dividing his baseball cards equally between himself, his brother, and his 3 friends. Roberto was left with 9 cards. How many cards did Roberto give away? Write and solve an equation to solve the problem.
PLZZZ HELP MEE ILL GIVE BRAINLIEST AND 50 POINTS!!!
Answer:
The answer would be 45.
Step-by-step explanation:
5*9=45
Answer:
45
Step-by-step explanation:
First we count how many people he split it between which is 5 and we have to remember the key word here is equal so if he was left with 9 then everybody else did as well. so we multiply 5 times 9 which is 45

Answer:
X= 11 Y= 7 Z= 55
Step-by-step explanation:
125+ z= 180. Z= 55.
55+ (8x+37) =180. —> 92 +8x = 180. Subtract 92 from both sides. 8x = 88. Divide both sides by 8. X =11. 8(11) + 37 = 125 for that angle. Then 125+(6y+13) = 180 —>138 + 6y = 180. Subtract 138 from both sides. 6y= 42. Divide both sides by 6. Y = 7
Answer: It should be:
X=11
Y=7
Z=55
Step-by-step explanation:
8x+37=125, 125 - 27 = 88 / 8x = 11
6y+13=z : 180-125 = z {55}
6y+13=55, 55-13 = 42 / 6y = 7

Answer:
18 and 162
Step-by-step explanation:
JUST REPOSTING THIS QUESTION UNTIL I GET A CORRECT ANSWER lol!
Answer:
3x+(8x+15=180
3x+8x+15)=180
11x+15=180
11=180-15
11x=165
x=165/11
x=15
What is the area? of this
Answer:
365 in^2

Kenneth Drew a scale drawing of an apartment the scale of the drawing was 2 meters:1 meter the living room is 6 m long in real life how long is the living room in drawing
Answer:
3 meters
Step-by-step explanation:
Given the scale drawing :
2m : 1m
Length of living room in real life = 6 m long
2 meter = 1 meter
Real life = scale drawing
If length = 6 meter long ;
using cross multiplication :
2 meter = 1 meter
6 meter = x
2x = 6
x = 6/2
x = 3 meter
Length of living room in drawing = 3 meters

Denise rode 3 kilometers on a bike. her friend clark rode 5000 meters on a bike
how much farther in meters did one person ride than the other?
[tex] \huge \purple{\tt{Answer:}} [/tex]
Denise rode 3 kilometres .
Clark rode 5000 metres which is 5 kilometres .
So , Clark rode 2 kilometres more than Denise .
Answer:
Step-by-step explanation:
1 km = 1000m
3km = 3000m
So difference = 5000 - 3000 = 2000m = 2km
Clark rode 2km more than denis
Is value of X in the equation 6x+3+4x= 1/2(9+10x)
Answer:
x = 0.3
Step-by-step explanation:
6x + 3 + 4x = 1/2 (9 + 10x)
=> 10x + 3 = 1/2 *9 + 5x
=> 5x + 3 = 9 / 2
=> 5x = 9 / 2 -3
=> 5x = (9 - 6) / 2
=> 5x = 3 / 2
=> x = 3 / 10
=> x = 0.3

Lucy, Luke, and Lilly went trick-or-treating on Halloween. After they finished, they compared the amount of candy they all had. Luke had twice the amount Lilly had, and Lucy had 15 less than 3 times the amount Lilly had. If together, they had 225 candies, how many candies did Lucy have? PLEASE HELP URGENT
Hi there!
Let think talk about these clues we have right now...
Luke is x2 more than Lily.
Luce is 45 less candy than Lily since 3 times 15.
225 candys in total...
Let make a random guess...
Lily: 70
Luke: 140
Lucy: 35
Total: 245
Now we know that there must be a half candy since it’s a odd number at the end of that...
Lily: 67.5
Luke: 135
Lucy: 22.5
Total: 225
But we are asked for only Lucy...
So the answer to this problem is 22.5.

linear equation.
Answer:
x=7
Step-by-step explanation:
3x-30=-9
3x=21
x=7
hope this helped! have a Blessed day!
3(x-10) =-9
3x - 30 = - 9
3x - 30+30= - 9+30
3x =21
X = 21/3.
X= 7
A farmer sells a dozen eggs at the market for 2.00 and one of his bags of gains for 5.00 he sold 5 time as many bags of grains as he has dozens of eggs. By the end of the day he has made 243.00 worth of sales. How many bags of grain did he sell
Answer:
45 bags
Step-by-step explanation:
Cost of a dozen eggs = 2
A bag of grain = 5
Let :
dozens of eggs sold = x
Bag of grains sold = 5x
Total sales worth = 243
Quantity sold * price
2* x + 5 * 5x
2x + 25x = 243
27x = 243
x = 243 / 27
x = 9
Bags of grains sold = 5x = 9*5 = 45 bags
