Ket [755]3 years ago
3 0

Answer:

2) 2x-6

Step-by-step explanation:

"6 less than" is subtracting 6 from "twice the value of x" or 2x. So the expression is 2x - 6.

Here it the question
Cerrena [4.2K]

Answer:

Variable A and variable B have a negative linear association.

Step-by-step explanation:

We are asked to find which best describes the association between variable A and variable B.

From the scatter plot we could clearly see that as the value of variable A are increasing the corresponding value of variable B is decreasing.

Also we could see that the points are linear.

Hence, the relationship that best describes variable A and variable B is:

Negative linear Association

The hyperbolic orbit of a comet is represented on a coordinate plane with center at (0, 4). One branch has a vertex at (0, 10) a
Anuta_ua [19.1K]

Remember that

If the given coordinates of the vertices and foci have the form (0,10) and (0,14)

then

the transverse axis is the y-axis

so

the equation is of the form

(y-k)^2/a^2-(x-h)^2/b^2=1

In this problem

center (h,k) is equal to (0,4)

(0,a-k)) is equal to (0,10)

a=10-4=6

(0,c-k) is equal to (0,14)

c=14-4=10

Find out the value of b

b^2=c^2-a^2

b^2=10^2-6^2

b^2=64

therefore

the equation is equal to

<h2>(y-4)^2/36-x^2/64=1</h2><h2>the answer is option A</h2>

Which statements are true about exponential decay functions? Check all that apply. The domain is all real numbers. As the input
lorasvet [3.4K]
<h2>Answer:</h2>

The correct options are:

  • The domain is all real numbers.
  • The base must be less than 1 and greater than 0.
  • The function has a constant multiplicative rate of change.
<h2>Step-by-step explanation:</h2>

We know that the exponential function is given by:

                f(x)=ab^x

where a>0 and b are constants.

Also, it represents a growth function if b>1

and a decay function if 0<b<1

where b is the base.

  • x belongs to whole of the real numbers( since the exponential function is well defined for all the real values of x.

Hence, the domain of the function is all the real numbers )

  • Also, the graph of a decay function decreases continuously i.e. with the increasing input value the output value decreases.
  • The exponential decay function always have a constant multiplicative rate of change i.e. b.
