Answer:

12

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form y*x=k or y=k/x

In this problem we have

For x=3 -----> f(x)=8

so

Find the value of k

f(x)*x=k

substitute the value of x and f(x)

8*3=k

k=24

therefore

the equation is equal to

f(x)=24/x

For x=2 -------> substitute in the equation and find the value of f(x)

f(x)=24/2=12

damaskus [11]
One Square Meter= 10.764 Square Feet.
The total area of the quilt in meters is 4.465m^{2}
As you're looking for square feet, you've then got to multiply this by 10.764
4.465*10.764= 48.06086 square feet.
Rounded, this is 48.06 square feet.
Hope this helps :)

Can someone answer this for me pls

Answer: Lin is the most consistent and I would want to have them on my team.

Why is this? Because their dots are more clustered together compared to the other distributions. Elena may have made the most shots (9) at one point, but her data set is very spread out and more unpredictable. The more spread out a data set is, the higher the variance and standard deviation. The range is also affected by how spread out the data set is since

range = max - min

So in a rough sense, the range can be used to estimate the variance and standard deviation. Though more accurate formulas are usually the better way to go.

Answer: 3y3+7y2+−4y+3

Step-by-step explanation:

3y2+y3+−5+4y2+−4y+2y3+8

Combine Like Terms:

=3y2+y3+−5+4y2+−4y+2y3+8

=(y3+2y3)+(3y2+4y2)+(−4y)+(−5+8)

=3y3+7y2+−4y+3

Carmen is using the quadratic equation (x + 15)(x) = 100 where x represents the width of a picture frame. Which statement about
Alekssandra [29.7K]
<span>We write the equation in the standard form which is:

ax^2 + bx + c = 0

(x + 15)(x) = 100
x^2 + 15x - 100 = 0
(x + 20) (x-5) = 0

The solutions are

x = -20 and x = 5

Therefore, the correct answer is option B. </span><span>The solution x = 5 should be kept, but x = –20 is unreasonable.</span><span>
