Answer:

b. {-9, 3}.

Step-by-step explanation:

x^2 + 6x - 27 = 0

We need 2 numbers whose product is -27 and whose sum is + 6.

These are + 9 and - 3. So the factors are:

(x - 3)(x + 9) = 0

(x - 3) = 0 or (x + 9) = 0

x = 3 or -9.

Answer: option b is the correct answer.

Step-by-step explanation:

The given quadratic equation is expressed as

x^2+6x-27=0

In order to solve the equation by factorization, the first step is to find two numbers such that their sum or difference is 6x and their product is

- 27x^2. The two numbers are 9x and - 3x. Therefore,

x^2 + 9x - 3x - 27 = 0

x(x + 9) - 3(x + 9) = 0

x - 3 = 0 or x + 9 = 0

x = 3 or x = - 9

Which of the following lines of Shelly's "On the Medusa of Leonardo Da Vinci in the
RUDIKE [14]

Answer:

A: Tis the melodious hue of beauty thrown  .

Explanation:

An appeal to the sense of hearing and sight will be something that presents an act that gives the readers a sense of the sounds in the writing. While an appeal to the sense of sight will present an image or a form of the picture to the readers. These types of sense appeals are used by writers to engage their readers' interest and keep them hooked.

In Percy Bysshe Shelly's poem "On the Medusa of Leonardo Da Vinci in the Florentine Gallery", the poet talks about the goddess Medusa but most importantly talks about the painting of "Medusa" by Da Vinci. The poem structured in the iambic pentameter scheme presents an image of Medusa and also how she was depicted by Da Vinci in his work. Out of the given options from the second stanza of the poem, the line that appeals to the sense of hearing and sight is<u><em> "Tis the melodious (hearing/ sound) hue of beauty thrown (sight)".</em></u>

Thus, the correct answer is option A.

PLS HELP I DONT UNDERSTAND
Norma-Jean [14]

Step-by-step explanation:

the average change rate is simply the change of the functional values in a given interval relative to the change of the input values.

in short

(f ( interval upper limit) - f (interval lower limit) ) /

(interval upper limit) - (interval lower limit)

and you know that f (x) is usually also called y (the functional result variable).

so, the upper limit is 0, the lower limit is -2.

y (or f (x)) is 6 and 10 at these points.

and we get

(6 - 10) / (0 - -2) = -4 / 2 = -2
