Hello,
Degre 5==> even number of imaginary roots and odd number of reals.

Real roots must be a divisor of 7.
Using Excel, we find


<span> <span><span> x  P(x) 
 </span><span>-7 0 </span>
<span> -6 1369
</span> <span> -5 1352
</span> <span> -4 867

 </span><span>4 3179
 </span><span>5 8112
 </span><span>6 17797
 </span><span>7 35000

So: one real root: 7 and 4 imaginary roots.

What is the vertical asymptotes of the function f(x)=x-2/x*2-3x-4
frozen [14]

Answer:

<h2>x = -1 and x = 4</h2>

Step-by-step explanation:

f(x)=\dfrac{x-2}{x^2-3x-4}\\\\\text{DOMAIN}:\\\\x^2-3x-4\neq0\\\\x^2-4x+x-4\neq0\\\\x(x-4)+1(x-4)\neq0\\\\(x-4)(x+1)\neq0\iff x-4\neq0\ \wedge\ x+1\neq0\\\\x\neq4\ \wedge\ x\neq-1\\\\\text{Therefore the vertical asymptotes are:}\\\\x=-1\ and\ x=4.

Leona [35]

Answer:

The number of miles Lori drive be 134 miles .

Step-by-step explanation:

Let us assume that the number of miles Lori be x.

As given

Lori rented a car for one day.

The daily rental rate was $12.50 plus 25 cents per mile.

As 1 dollar = 100 cent

1\ cent = \frac{1}{100}\ dollar

25\ cent = \frac{25}{100}\ dollar

25\ cent = 0.25\ dollar

As given

The total cost of her rental was $46.

Than the equation becomes

46 = 12.50 + 0.25x

46 - 12.50 = 0.25x

33.5 = 0.25x

x = \frac{33.5}{0.25}

x = 134 miles

Therefore the number of miles Lori drive be 134 miles .
