What is the value of x?

x = 5.5y - 1

Step-by-step explanation:

this is an equilateral triangle.

(you know that because the sides all have a line through them, meaning they are equal.)

this means that the angles are also equal.

using that, you can make this equation:

7x - 3 = 11y + 5

7x = 11y + 5 - 3

7x - 11y = 2

7x = 11y - 2

x = (11y - 2 )/2

x = 5.5y - 1

I think that's as simplified as it goes..

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
