The point (2, 18) is an ordered pair in a proportional relationship. What equations represents this relationship?


y = 1/9x

y = 18x

y = 9x

y = 2x

Answers

Answer:

y = 9x

Step-by-step explanation:

If you plug in the point into each equation, you get:

y = 1/9x

18 = 1/9 * 2

18 = 2/9

not true

y = 18x

18 = 18 * 2

18 = 36

not true

y = 9x

18 = 9 * 2

18 = 18

true, so this is the answer

y = 2x

18 = 2 * 2

18 = 4

not true

si por que esta bien hecha

1.Distribute

1 5n+24-4(n-3(+6-2n=105

15n+24-4n+12+6-2n=105

2.Add the numbers

15n+24-4n+12+6-2n=105

15n+42-4n-2n=105

3.Combine like terms

15n+42-4n-2n=105

9n+42=105

4.Subtract  42 from both sides of equation

9n+42=105

9n+42-42=104-42

Simplify

Subtract

9n+42-42=105-42

9n=105-42

subtract again

9n=63

Divide both sides of the equation by the same term

9n=63

9n/9=63/9

Simplify

Cancel terms that are in both the numerator and denominator

9n/9=63

n=63/9

Divide the numbers

n=7

so the answer is n=7

A rectangle has the height of X and the width of 7X -4

Answers

Answer:

Step-by-step explanation:

Area = x(7x-4) = 7x^2-4x

A rectangle has the height or breadth of [tex]X[/tex] and the width or length of  [tex]7X -4[/tex] , then area of rectangle will be   [tex](7X^2-4X)[/tex].

What is rectangle ?

Rectangle is a shape with four sides and having internal angles of  . Two of the sides are longer than the other two. The opposite sides of the rectangle are equal in length.

Area of rectangle [tex]= \text(Length \ * \ Breadth)[/tex]

We have,

Length [tex]=7X-4[/tex]

Breadth [tex]= X[/tex]

So, Using the above formula

Area of rectangle [tex]= \text(Length \ * \ Breadth)[/tex]

                              [tex]=X \ * \ (7X-4)[/tex]

                              [tex]=7X^2 - 4X[/tex]

So, the   Area of rectangle is [tex]7X^2 - 4X[/tex] which is find out using above given formula.

Hence, we can say that a rectangle has the height or breadth of [tex]X[/tex] and the width or length of  [tex]7X -4[/tex] , then area of rectangle will be   [tex](7X^2-4X)[/tex].
