How do you use the slope to prove lines are parallel or perpendicular?

1 answer:

8 0

For this, there is two rules. The common slope-intercept form is y=ax + b. For parallel, b can change, but a, or the slope, can't change. But for perpendicular, the a should be -1/a, where the answer for times the original equation, or a, and the second equation, or -1/a, is -1. To prove these two rules, you can graph it using random numbers but follow these two rules. if you have any part that don't understand for this answer, feel free to ask in the "Ask for details" section.

The ____ of ____ property allows you to rewrite . xa· xb as xa + b.

gregori [183]

The rule of distributive property allows you to rewrite xa + xb as x (a + b).

So if x = 2, a = 3 and b = 4, xa + xb = x(a + b)
(2 * 3) + (2 * 4) = 2 (3 + 4)
6 + 8 = 14
14 = 14
...and so on. You may try it yourself with different variations.

What is the rational expression in simplest form? State any restrictions on the variables.

allochka39001 [22]

According to the question, the given rational expression can be simplified which is as shown below:

Rational expression = $\frac{12-4x}{x^{2} -9}=\frac{4(3-x)}{(x-3)(x+3)}$

For the simplification of the given expression, calculate the factors of the numerator as well as denominator terms and divide them from each other. In this change the sign of the expression before dividing with each other.

Rational expression = $\frac{-4}{(x+3)}$

The rational expression are also known as polynomial expression. The highest degree of these expression is two. And these expression uses concept of factor rule.

Therefore, the final expression is $\frac{-4}{(x+3)}$

What is polynomial expression?

Polynomial expression are those equation whose highest degree is two. It is also called as quadratic equation. And it is simplified by performing the factors on the given expressions.

The narrator uses the phrase "making trial of

Volgvan

The narrator uses the phrase "making trial of everything" from the passage to present Eppie as curious. The correct option is B.

Given a passage which is shown in attached images.

Option B is the best answer. The first paragraph describes Eppie as "a creature of endless dreams and ever-increasing desires", someone who "tried everything to the test". In this context, his "trying everything" can be read as acting on his curiosity by trying to experience the world around him.

Options A, C and D are incorrect because in the context of her "doing everything to check", Eppie could be seen as curious, unfriendly (option A), disobedient ( option C) or criticize (option D).

Hence, the narrator uses the phrase "making trial of everything" from the given passage to present Eppie as curious.
