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

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.

Jayden used a Groupon at the local pizza shop. Instead of paying $15, for the pizza, he paid $12.
Haley and Arianna agree that the percent of decrease is 20% but their explanations differ. Haley says to find the 20%, you have to determine what percent of 15 is 12. Arianna thinks you have to determine what percent of 15 is 3. Who is correct?

Answers

Answer:

Arianna is correct

Step-by-step explanation:

She is correct because they need to find how much is the discounted price, which is 3. So to see what percentage it is, they need to see how much 3 is worth in comparison to 15. If we spilt 15 into 5 parts to make every part worth 20%, the answer would be 3. Thus Arianna is correct.

arianna is the correct answer

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.

Answers

I have no clue if I even did this right but here’s my work. I don’t wanna get it wrong for you!
Answer: x=11


Explanation: The anglers in a triangle must all add to 180.

Therefore, we can use the equation 180=3x+28+5x+52+2x-10

Combing like terms gives us 180=10x+70

Solving for x gives us 11.

To check our work, we can plug in 11 for x.

3(11)+28+5(11)+52+2(11)-10=180.
