Answer:

x = 3.5y

Step-by-step explanation:

Simplifying

3x + 8y + -5x + -1y = 0

Reorder the terms:

3x + -5x + 8y + -1y = 0

Combine like terms: 3x + -5x = -2x

-2x + 8y + -1y = 0

Combine like terms: 8y + -1y = 7y

-2x + 7y = 0

Solving

-2x + 7y = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-7y' to each side of the equation.

-2x + 7y + -7y = 0 + -7y

Combine like terms: 7y + -7y = 0

-2x + 0 = 0 + -7y

-2x = 0 + -7y

Remove the zero:

-2x = -7y

Divide each side by '-2'.

x = 3.5y

Simplifying

x = 3.5y

Answer:

The set of coefficients asociated with the given polynomial in ascending order is $[C] = \{4,0,5\sqrt{3}\}$ .

Step-by-step explanation:

Let $y = 5\sqrt{3}\cdot x^{2}+4$ , which is a polynomic function, defined as:

$y = \Sigma_{i=0}^{n}c_{i}\cdot x^{i}$ (1)

Where:

$c_{i}$ - i-th Coefficient.

$x^{i}$ - i-th Power.

$n$ - Grade of the polynomial.

We notice that given polynomial has degree 2 and can be rewritten by applying this definition:

$y = 4 + 0\cdot x + 5\sqrt{3}\cdot x^{2}$

Then, the set of coefficients asociated with the given polynomial in ascending order is:

$[C] = \{4,0,5\sqrt{3}\}$
