Which equation has a constant of proportionality equal to 7?
A. 4y = 28x
B. 7y = 28x
C. 28y = 4x
D. 28y = 7x
The solution is Option A.
The equation which has a constant of proportionality k = 7 is 4y = 28x
What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the equation be represented as A
Now , the value of A is
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
Now , the equation is
4y = 28x
On simplifying the equation , we get
Divide by 4 on both sides of the equation , we get
y = 28x/4
y = 7x
y = 7x is of the form y = kx where the value of k is 7
Therefore, the value of k is 7
Hence , the value of proportionality constant is 7

Pls help its not that hard, im in 7th grade
i think it's 20 but i'm not that sure
Answer:
7/5
Step-by-step explanation:
To determine the proportionality you'll have to multiply the answers by x to get y. In this case 7/5 is the answer.
Calculations
0 x 7/5 = 0
20 x 7/5 = 28
40 x 7/5 = 56

Hope this helps :)
-ilovejiminssi♡
a(8x + 7) = 4x + 3.5
8ax + 7a = 4x + 3.5
equating coefficients of x : 8a = 4 so a = 1/2
also 7a = 3.5 so a = 1/2
The value of a is 1/2

Two linear functions are represented in different formats.
Function 1:
x y
0 −2
2 0
3 1
5 3
Function 2:
Graph of a line passing through the point begin ordered pair negative 2 comma 0 end ordered pair and the point begin ordered pair 0 comma 4 end ordered pair.
Which statements are true?
Select each correct answer.
Function 1 has a greater rate of change than function 2.
Function 2 has a greater rate of change than function 1.
Function 1 has a greater y-intercept than function 2.
Function 2 has a greater y-intercept than function 1.
The statements that are true are;
Function 2 has a greater rate of change than function 1.
Function 2 has a greater y-intercept than function 1.
Step-by-step explanation:
Given that function 1 has the table;
x y
0 -2
2 0
3 1
5 3
Finding the slope of the linear function gives the rate of change of the function. In this case,
m=Δy/Δx
m=3-1/5-3 = 2/2 =1
The equation of the linear function is given as;
m=Δy/Δx
y-3/x-5= 1
y-3=x-5
y=x-5+3
y=x-2
y-intercept is -2
In function 2, the line passes through points (-2,0) and (0,4)
Finding the slope of the line,
m₁=Δy/Δx
m₁=4-0/0--2
m₁= 4/2 =2
Rate of change is 2
Finding the equation of the line
y-4/x-0 = 2
y-4=2(x-0)
y-4 =2x
y=2x+4
The y-intercept is 4
The statements that are true are;
Function 2 has a greater rate of change than function 1.
Function 2 has a greater y-intercept than function 1.

Hip hop music makes up 75% of Landon's music library. If he has downloaded 120 hip hop songs, how many songs does Landon have in his music library? (Explain your answer/show your work)
Answer: 160 songs.
Step-by-step explanation:
75% hip hop music - 120 songs
100% all music - x songs
Let's write the proportion:
[tex]\dfrac{120}{75} =\dfrac{x}{100} \\\\75x=120 \cdot 100\\75x=12000\\75x : 75 = 12000 : 75\\x = 160[/tex]
Thus, Landon have 160 songs in his music library.
