Which equation has a constant of proportionality equal to 7?
A. 4y = 28x
B. 7y = 28x
C. 28y = 4x
D. 28y = 7x

Answers

A is correct.

Reasoning: 4 x 7 = 28


good luck!

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

the expressions a[8x+7] and 4x+3.5 are equivalent. what is the value of a

Answers

Answer:

[tex]a=0.5[/tex]

Step-by-step explanation:

Divide each term by  [tex]8x+ 7[/tex]  and simplify.

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.

Answers

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.

Micheal is buying Presents for a gift exchange for his four friends. He would like to spend less than $160 total. On average, how much can he spend on each person? Write out the Inequality as well.

Answers

Answer:

Micheal will spent 40 $ on each of his friends

Step-by-step explanation:

160$÷4=40$

why because there is 160 dollars to spend and there are 4 friends now you need to divide that to get the amount of money you need.

Answer:

x≤40. He can spend about $40 on each friend

Step-by-step explanation:

I got this because a number x is the amount of money he can spend on a friend on average. The inequality is then written like 4x≤160. You then try to get "x" on its own by dividing both sides by 4 (both sides being 4x and 160). then you get the average amount Michael can spend on his friends.
