You average the x's and average the y's.

This means add x+x and divide by 2. And add y+y and divide by 2. See image.

Answer:

{x | x ≠ -1, 2, 4}

Step-by-step explanation:

Domain: input values (x-values)

Asymptote: a line which the curve gets infinitely close to, but never touches.

Hole: a point on the graph where the function is not defined.

From inspection of the graph:

As vertical asymptotes and holes restrict the domain of a rational function, the domain is  {x | x ≠ -1, 2, 4}

Answer:

there are 20 students in mr.clarks fourth grade class there are 5 times as as many students in the entire fourth grade class as there are in mr.clacks. which equation can be used to determine the number of students,n, in the entire fourth grade?

n= 20(5)

100 kids in the fourth grade

or

there are 140 kids in the 4 th grade

Step-by-step explanation:

the equation is n=20(5)

because 20(5) is the same as 20×5 so that 8s the equation

Answer:

To create a "mini-triangle", we could use any number pairs (coordinates matter). We can use the side lengths of 4, 6, and 7 as they are the smallest pairs. It's a pretty easy concept which I'm sure you'll be able to grasp (I know you're smart! :) ). Ask your teacher if you have more questions. <3

Good luck!,

Answer:

2.27

Step-by-step explanation:

Let's start the sum as follows:

x³ = 8

X × X × X = 8

This means there are 3 number which after Multiplication gives answer 8.

If 2 is multtiplied 3 times it will give you 8

Thus the answer of x is 2

x = 2.

x^3 = -8

The cube root of 8 is 2 = 2 x 2 x 2 is 8.

But, the answer is negative, which means that the cube root of -8 must be -2.

-2 x -2 x -2 = -8

x = -2

Answer:

10.9 units

Step-by-step explanation:

Let the hight of the wall be " x ".

( Height = x )

Here,

12 foot ladder is the hypotenuse side.

( Hypotenuse = 12 )

5 feet away is the base side.

( Base = 5 )

Formula : -

Height² + Base² = Hypotenuse²

x² + 5² = 12²

x² + 25 = 144

x² = 144 - 25

x² = 119

x = √119

x = 10.9 approximately

Therefore,

High up the wall does the top of the ladder reach is 10.9 units.

Answer:

Step-by-step explanation:

y-3=15

+3 +3

if you add 3 to the other side, you would get:

y=18

The length of the side labeled x is Option B.  [tex]\sqrt{21}[/tex].

Pythagorean theorem is a basic principle to be applied when determining the unknown side of a given right triangle when the values of two sides are given. The theorem states that;

/Hyp/^2 = /Adj/^2 + /Opp/^2

From the triangle given, we have;

/Hyp/^2 = /Adj/^2 + /Opp/^2

x^2 = 4^2 + ((5)^1/2)^2

      = 16 + 5

      = 21

x = 21^1/2

  = [tex]\sqrt{21}[/tex]

The length of the side labeled x is [tex]\sqrt{21}[/tex]. Option B.

Explanation:

Lamont should sample only registered voters to predict who will be elected mayor

A survey is a research method used for collecting data from a predefined group of respondents to gain information and insights into various topics

Since Lamont is trying to predict who will be elected, surveying people that are not registered to vote will not give him an accurate prediction.  If someone is not registered to vote, they cannot vote for any candidate.

To get more accurate results, Lamont should only sample people that are registered voters.

Answer:

The mode would not increase or decrease.

Step-by-step explanation:

I say this because the mode is the value(s) in the data set that occur most frequently. 30 is the mode before adding 80 because 30 is in the set 3 times, more than the other values. Because 80 would be the only 80 in the set it would not become the mode once added. I hope this explained my reasoning and helped!

Answer:

Attach the graph options so i can help...

Step-by-step explanation:

Answer:

Statement 1 - false

A function is one-to-one or many-to-one.

One-to-one means each value in the range (y-values) corresponds to exactly one value in the domain (x-values)

Many-to-one means some values in the range (y-values) correspond to more than one (many) value in the domain (x-values).

Therefore, as some y-values correspond to more than one x-value, this is a many-to-one function.

The true statement should be:

The relation is a function because some y-values correspond to more than one x-value.

Statement 2- true

The domain is the set of input values (x-values).  Therefore, the domain is 3 ≤ x ≤ 8 as the smallest x-value is 3 and the highest x-value is 8.

Statement 3 - true

The range is the set of output values (y-values).  Therefore, the range is {6, 7, 8, 10} as these are the y-values of the ordered pairs.

Given:

Angle 6 = 25 degrees

To Find:

The value of Angle 7

Solution:

We know that,

the value of Angle 6 is equal to 25 Degrees

Since Angle 6 and Angle 7 together comprise of a Straight Line, this means that they are Supplementary Angles.

Therefore,

Angle 6 + Angle 7 = 180 degrees

This implies that,

25 degrees + Angle 7 = 180 degrees.     (since Angle 6 = 25 Degrees)  

Angle 7 = (180-25) degrees

Thus ,

Angle 7 = 155 degrees

Hence, Angle 7 is  155 degrees (Option 1)
