Answer:

Option D. $x=-3$

Step-by-step explanation:

we have

$f(x)=\frac{5x^{4}-7}{x+3}$

we know that

The denominator cannot be equal to zero

therefore

To find the equation of the vertical asymptote equate the denominator to zero

$(x+3)=0$

$x=-3$ -----> equation of the vertical asymptote

10. The perimeter of the table shown is 16 feet. Write an equation in

Aliun [14]

Answer:

p = 2

q = 6

r = 16

x = 5 feet

Step-by-step explanation:

The perimeter of the rectangle is

$P=2(\text{Width}+\text{Length})$

In your case,

Width = 3 feet

Length = x feet

So, the perimeter is

$P=2(3+x)\\ \\P=6+2x$

Since the perimeter is 16 feet, we have

$2x+6=16$

Hence,

p = 2

q = 6

r = 16

Solve this equation for x:

$2x+6-6=16-6\\ \\2x=10\\ \\x=\dfrac{10}{2}=5\ feet$

Problem 3

Murljashka [212]

Answer:

$-\frac{2}{5}$

Step-by-step explanation:

Given expression:

2x + 5y = -10

The equation of a straight line is;

y = mx + c

y and x are the coordinates

m is the slope

c is the intercept

Now;

let us write the given expression in slope intercept format;

2x + 5y = -10

5y = -2x - 10

y = $-\frac{2x}{5}$ - 2

So, the slope of the line is $-\frac{2}{5}$

Does any one know the answer?

nekit [7.7K]

Answer: option C

find f(x) - g(x)

f(x)= $-9x^2 - 7x + 12$

g(x) = $3x^2 - 4x -15$

To find f(x) - g(x) we plug in the functions and subtract

$-9x^2 - 7x + 12- ( 3x^2 - 4x -15)$

Remove the parenthesis and change the sign of each term

$-9x^2 - 7x + 12 - 3x^2 + 4x +15$

Combine like terms

$-12x^2 - 3x + 27$

So option C is correct
