22+-7=15 3y = 15 then 
Divide each side by '3'. y = 5
Simplifying y = 5
so your answer is going to be 5

Choose the four expressions that are equivalent to 3^-4 ?

Ivan

3^(-4) means "one over 3^4"

1/(3^4)

That's equal to

1/81

and

(1/3)^4

This is also equal to 3^2/3^6.

So four of those are correct.

Katrina wants to build a fence around her Square Garden the garden has an area of 121 square feet How much Fencing will Katrina

Sindrei [870]

Answer:

The perimeter of the fencing is 44 feet (Option D)

Step-by-step explanation:

Area and Perimeter

A square shape of side length (a) has an area given by:

$A = a^2$

And its perimeter is calculated as:

P = 4a

The area of Katrina's square garden is given as A=121 square feet. We need to calculate the side length by solving for a:

$a=\sqrt{121}$

a = 11 feet

Once we know the value of a, then we calculate the perimeter:

P = 4*11 = 44

The perimeter of the fencing is 44 feet (Option D)

F(x)=x-1/x^2-x-6 which is the graph of

hoa [83]

Answer:

The graph is attached below.

Step-by-step explanation:

As you have not added the graph, so I will be solving the function for a graph.

Given the function

$f\left(x\right)=x-\frac{1}{x^2}-x-6$

$x-\mathrm{axis\:interception\:points\:of\:}-\frac{1}{x^2}-6:$

$\mathrm{x-intercept\:is\:a\:point\:on\:the\:graph\:where\:}y=0$

$-\frac{1}{x^2}-6=0$

$-1-6x^2=0$

$\mathrm{No\:Solution\:for}\:x\in \mathbb{R}$

$\mathrm{No\:x-axis\:interception\:points}$

$y-\mathrm{axis\:interception\:point\:of\:}-\frac{1}{x^2}-6:$

$y\mathrm{-intercept\:is\:the\:point\:on\:the\:graph\:where\:}x=0$

As we know that the domain of a function is the set of input or argument values for which the function is real and defined.

$\mathrm{Domain\:of\:}\:-\frac{1}{x^2}-6\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x0\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:0\right)\cup \left(0,\:\infty \:\right)\end{bmatrix}$

$\mathrm{Since}\:x=0\:\mathrm{is\:not\:in\:domain}$

$\mathrm{No\:y-axis\:interception\:point}$

$\mathrm{Asymptotes\:of}\:-\frac{1}{x^2}-6:\quad \mathrm{Vertical}:\:x=0,\:\mathrm{Horizontal}:\:y=-6$

$\mathrm{Range\:of\:}-\frac{1}{x^2}-6:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)$

The graph is attached below.

The sales tax on a surfboard is $12. What is the percent of sales tax if it is $240

Mazyrski [523]

Answer: Percentage of sales tax will be 5%.

Step-by-step explanation:

Since we have given that

Original amount of a surfboard = $240

Sales tax on a surfboard = $12

So, Percentage of sales tax will be

$\frac{Sales\ tax}{Original\ price}\times 100\\\\=\frac{12}{24}\times 100\\\\=\frac{1}{2}\times 100\\\\=\frac{100}{2}\\\\=5\%$

Hence, Percentage of sales tax will be 5%.
