Answer:

<em> f ( x ) = - 2x^2 + 3x + 1</em>

Step-by-step explanation:

If f (x ) extends to → − ∞, as x→ − ∞ , provided f(x) → − ∞, as x → +∞, we can rewrite this representation as such;

− ∞  < x < ∞, while y > − ∞

Now the simplest representation of this parabola is f ( x ) = - x^2, provided it is a down - facing parabola;

If we are considering a down - facing parabola, the degree of this trinomial we should create should be even, the LCM being negative. Knowing that we can consider this equation;

<em>Solution; f ( x ) = - 2x^2 + 3x + 1</em>, where the degree is 2, the LCM ⇒ - 2

Makaila read 44 pages of her book yesterday and 2/3 of the book today. If she read a total of 200 pages in the past two days how
pogonyaev

Answer:

Total number of pages in the book is 234.

Step-by-step explanation:

Let us assume that the total number of pages in the book = <em>x</em>

Now, it is given that Makaila read 44 pages yesterday.

Also, Makaila read two-third of the book today. As we have assumed that, there are a total of x number of pages in the book, so we can say that Makaila read two-third of <em>x </em>number of pages today.

Number of pages read by Makaila today = \frac{2}{3}\;of\;x=\frac{2}{3}\times\;x=\frac{2x}{3}

Now, it is also given that, Makaila read a total of 200 pages in the past two days.

∴ according to question,

Pages read yesterday + Pages read today = 200

⇒44+\frac{22x}{3}=200

⇒\frac{44\times3+2x}{3}=200

⇒\frac{132+2x}{3}=200

⇒132+2x=200\times3\;\;\;\;\;\;\;\;\;[On\;cross-multiplying]

⇒132+2x=600

⇒2x=600-132

⇒2x=468

⇒x=\frac{468}{2}=234

∴ Total number of pages in the book = <em>x</em> = 234
