Answer:

x -22

Step-by-step explanation:

Sum = -7            (-22+15 = -7)

Product = -330   (-22*15 = -330)

Factors = -22 , 15

x² - 7x - 330 = x² +15x - 22x - 22 *15

                    = x(x + 15) -22(x + 15)

                   = (x +15)(x -22)

\frac{x^{2}-7x-330}{x + 15}=\frac{(x+15)(x-22)}{(x+15)}\\\\ =x - 22

Given f(x) =
inysia [295]

The end behavior of the given function (range) is x< 4 or x > 4. So, f(x) < 4 or f(x) > 4. The solution in interval notation is \mathbf{(-\infty, 4) \cup (4, \infty)}.

The last option is correct.

<h3>What is the range of the function?</h3>

The end behavior of the given function f(x) = (8x+1)/2x-9 wants us to identify the range of the given function.

The range is the set of values of the dependent variable for which a function is defined. The function range is the combined domain of the inverse function.

From the information given:

\mathbf{f(x) = \dfrac{8x +1}{2x -9 }}

Inverse of \mathbf{\dfrac{8x +1}{2x -9 }} becomes \mathbf{f(x) = \dfrac{1+9x}{2(-4+x) }}

The domain of the inverse is x< 4 or x > 4. So, f(x) < 4 or f(x) > 4. Now, representing the solution in interval notation, we have:

\mathbf{(-\infty, 4) \cup (4, \infty)}

Me ajudem com a 3º questão
Alisiya [41]

I can't read that language but I'll guess it says write a second degree equation then solve for n when d=10.

10 = \dfrac{n(n-3)}{2}

20 = n^2 - 3n

n^2 - 3n - 20 = 0

Answer: n² - 3n - 20 = 0

That doesn't factor so there is no integer n solution.

That means there are no polygons with 10 diagonals.

n = \frac 1 2(3 \pm \sqrt{89})

What is the value of s in the equation 3 r equals 10 plus 5 s, when r equals 10?
Artemon [7]

Answer:

s = 4

Step-by-step explanation:

3r = 10 + 5s

3×10 = 10 + 5s

5s = 30 - 10

5s = 20

s = 20 : 5

s = 4
