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
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].

15n+24-4n+12+6-2n=105
2.Add the numbers
15n+24-4n+12+6-2n=105

3.Combine like terms
15n+42-4n-2n=105

9n+42=105
9n+42-42=104-42

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
