Is 4500 a rational number whole number or integer

Answer:

4500 is a rational number.

Because rational number consist of whole number and integer.

Step-by-step explanation:

Whole numbers start from 0 and continue so on.

W = {0, 1, 2, 3, 4, 5.......}

Integers are the numbers 0 and both positive and negative numbers.

Z = {0, ±1, ±2, ±3, ±4.......}

Rational numbers are in the form of where q ≠ 0.

Note: All the whole numbers and integers can be written in the form of .

For example, 5 can be written as

and -25 =

Conclusion:

The rational numbers consist of both the whole numbers and integers.

So, we can say 4500 is a whole number, it is an integer and it is also called rational number.

It is rational, whole number and an integer.

Find v(w+3) for v(w)=2w-1

So we have v(w) = 2w - 1

Now we make the following change: w ---> w +3.

So we change every "w" into a "w+3" as follows:

v(w) = 2w - 1 --------> v(w+3) = 2*(w+3) - 1

Let's solve this.

2*(w+3) - 1

2*w + 2*3 - 1

2w + 6 - 1

2w + 5

So

v(w+3) = 2w + 5

Now we make the following change: w ---> w +3.

So we change every "w" into a "w+3" as follows:

v(w) = 2w - 1 --------> v(w+3) = 2*(w+3) - 1

Let's solve this.

2*(w+3) - 1

2*w + 2*3 - 1

2w + 6 - 1

2w + 5

So

v(w+3) = 2w + 5

Joe scored 10 points in the basketball game. This is 2 more than one-sixth of the points scored by the team. Which equation, when solved for x, gives the number of points scored by the team?

(1/6) x + 2 = 10

Step-by-step explanation:

Step 1 :

Let x be the number of points scored by the team.

Given Joe has scored 2 points more than one sixth of the point scored bynthe team

Step 2:

Based on the above given information the equation which gives the points scored by Joe is as follows:

(1/6) x + 2

Given that Joe has scored 10 points, we have

(1/6)x + 2 = 10

Step 3:

When we solve the above equation for x , we get the total number of points scored by the team

Answer:

c)

x/6+2=10

Step-by-step explanation:

The answer is C on USATP

Consider the equation 5x+7=22 What two operations are represented in this equation??

How would you "undo" each of those operations

Which operation should you "undo" first why?? Please I need help

The two operations being represented are subtraction and division. ( subtract 7 from 22, then you have 5x=15, and then divide by 5 to get x=3) to "undo" it you would just use the opposite if each operation (so use addition to add 7 back to 15, and then multiply 5 times 3 to get the original equation on 5x+7=22. I assume you would undo it in the reverse order that you did it the first time. Hope that helped!

You should subtract 7 from both sides and then divide by 4 on both sides and that will be you answer for x and then plug in x to make sure you have the correct answer

Pre-Calc help: Write the general equation for the circle that passes through the points (1, 1), (1, 3), and (9, 2).

You must include the appropriate sign (+ or -) in your answer. Do not use spaces in your answer.

8x² + 8y²___x___y = 0

Answer:

Step-by-step explanation:

Let the equation be :

The point (1,1) must satisfy this equation.

Similarly, the point (1,3) must satisfy:

Also for the point (9,2), we have:

Solving the equations (1), (2) and (3) simultaneously, we get:

We Substitute this values to get:

Multiply through by 8 to get:
