The two equations represent the proportional relationship.

y=3x and y=12x are proportional relation ship equations

proportion equations can be defined as

If we change x the y will change in the same proportion.

<h3>What is the proportional relationship?</h3>

Proportional relationships are relationships between two variables where their ratios are equivalent.

Another way to think about them is that, in a proportional relationship, one variable is always a constant value time the other.

That constant is known as the constant of proportionality.

proportional relationship equation contain (0,0) points

If we put x=0

This will give us,y=0

If we put x=0, in y=12x

It will give y=0

put if we put x=0 in

y=3x it will give us y=0

hence these two equations represent the proportional relationship.

Rashid [163]

Answer:

List_of_students = {}; //Structure array that contains the scores of students and Names

Number_of_students = size(List_of_students);

Average_score ; //Variable Stores average score

Below_Average = []; //That is initially filled with zeros

Highest_score ; //Initialize variable to store highest score

for ( i = 0 ; i < Number_of_students; i = i + 1)

{

Average_score = Average_score + List_of_students(i);

if ( i = 15)

{

Average_score = Average_score / Number_of_students;

}

for ( j = 0; j < Number_of_students ; i = i + 1)

{

if ( List_of_students(j) < Average_score)

{

print( "student %name got %score , List_of_students(j), List_of_students(j) )

}

Compare_Score = 0; //Variable to compare score

for ( k = 0; K < Number_of_students; k = k+1)

{

if ( List_of_students(k) => Compare_Score)

{

Compare_Score = List_of_students(k);

}

Highest_Score = Compare_Score;

Pls help (kinda easy)

3241004551 [841]

Answer:

$f(x)=(2x+1)(2x-1)$ .

Step-by-step explanation:

We want to convert the function into the form that let's us easily find the x-intercept, and it would be for the form $(ax+b)(cx+d)$ because then we can find the x-intercept in the following manner:

$(ax+b)(cx+d)=0$

$x=-b/a$

$x=-d/c$

We factor our function $f(x)=4x^2-1$ and get

$\boxed{f(x)=(2x+1)(2x-1)}$

Now this form let's us easily find the x-intercepts:

$x=-1/2$

$x=1/2$

and so we pick the second choice: f(x)=(2x+1)(2x-1).

PLEASE HELP! 15PTS! GIVE EXPLANATION!

Tanzania [10]

1/3m +3 - 5/6m= -15
I am going to change the first fraction to match the second fraction
2/6m +3 - 5/6m= -15
Simplify by subtracting 5/6m from 2/6m
-3/6m +3 = -15
Subtract 3 from each side
-3/6m = -18
Take the minus signs off
3/6m = 18
Simplify
1/2m = 18
Divide by 1/2 on each side
m= 18 ÷ 1/2= 36
Option D, m is 36

Hope this helped
