The expressions are simplified to 2x and \frac{2}{(x+ 1)(x - 1)}

<h3>How to simply the expressions</h3>

1.

Given the expression;

\frac{8x^2 - 4x}{4x - 2}

Let's factorize the numerator;

\frac{2x( 4x - 2)}{4x - 2}

Factor the common terms, we have;

2x

2. \frac{1}{x-1} - \frac{2}{x} + \frac{1}{x + 1}

Find the Lowest common multiple

\frac{x(x+ 1) - 2 (x+ 1)(x - 1) + x(x-1)}{x(x-1)(x+ 1)}

expand the brackets

\frac{x^2 + x -2(x^2 -x + x -1) + x^2 -x}{x(x-1)(x+ 1)}

\frac{x^2+x - 2x^2 -2 + 2x + 2 + x^2 - x}{x(x+1) (x -1)}

collect like terms

\frac{2x}{x(x+ 1) (x-1)}

Divide common terms

\frac{2}{(x+ 1)(x - 1)}

Thus, the expressions are simplified to 2x and \frac{2}{(x+ 1)(x - 1)}

Use the Pythagorean theorem to find the length of the leg in the triangle shown below 12 15
Norma-Jean [14]

Answer:

9 = x (assuming 15 is the hypotenuse)

Step-by-step explanation:

15^2 = 12^2 + x^2

225 = 144 + x^2

subtract 144 from both sides

81 = x^2

square root both sides

9 = x

(-3, 6) &amp; m = -¹/2 what’s this equation in point slope form
Gre4nikov [31]

The equation of the line in point-slope form is <u>y - 6 = (-1/2)(x - (-3))</u> which can be simplified as <u>x + 2y = 9</u>.

The equation of a line that has a slope m, and passes through the point (x₁, y₁) is given by the point-slope form of a line, which can be shown as:

(y - y₁) = m(x - x₁).

In the question, we are asked to find the equation of the line in point-slope form, that passes through the point (-3, 6) and has a slope m = -1/2.

We know that the equation of a line that has a slope m, and passes through the point (x₁, y₁) is given by the point-slope form of a line, which can be shown as:

(y - y₁) = m(x - x₁).

Taking (x₁, y₁) as (-3, 6) and m = -1/2, in the point-slope form, we get the equation of the line as;

y - 6 = (-1/2)(x - (-3)).

This can be simplified as:

2y - 12 = - x - 3,

or, x + 2y = 9.

Thus, the equation of the line in point-slope form is <u>y - 6 = (-1/2)(x - (-3))</u> which can be simplified as <u>x + 2y = 9</u>.
