i’m stuck on this question
Answer:
See below
Step-by-step explanation:
So you are moving the decimal to the right, right?
This action would make the number bigger.
For this explanation I will use the example 7.2
So lets move the decimal 3 to the right.
You get 7200.
Now try dividing 7200 by 100 = 72
This did not get us the original # 7.2
Now lets divide 7200 by 1000 = 7.2
Now that we got the original #, switch the operation and multiply 7.2 by 1000
7.2 x 1000 = 7200
Answer = multiplying the number by 1,000

the value of 7y–2 is 10 more than the value of 2y
Answer:
y=12/5 (in decimal notation y=2.4)
Step-by-step explanation:
the value of 7y-2 = 10 more than 2y
7y-2 = 10+2y
7y-2y = 10+2
5y = 12
y = 12/5
y = 2.4

Definition of a conditional:
A conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences. For this conditional statement, P is called the hypothesis and Q is called the conclusion. Intuitively, “If P then Q” means that Q must be true whenever P is true.

Answer:
4x-2
Step-by-step explanation:
First, distribute the minus sign.
-2x+3-(5-6x)
-2x+3+ -1(5)+ -1(-6x)
-2x+3+ (-5) + (6x)
-2x+3-5+6x
Next, combine like terms.
-2x+3-5+6x
(-2x+6x)+(3-5)
4x+(-2)
4x-2
Answer:
4x - 2
Step-by-step explanation:
-2x + 3 - -5 + 6x ( First distribute the parenthess and apply minus-plus rules making it -2x+3-5+6x )
-2x + 6x + 3 - 5 ( Group the equation like this putting like terms together)
4x + 3-5 ( From there add -2x and 6x- like terms to get 4x)
4x -2( After that subtract 3-5 ad the answer is -2)
THE FINAL ANSWER BECOMES 4x - 2

The mean of 6 numbers is 3 the median is 6. List the numbers
Answer:
Step-by-step explanation:
We have 6 numbers, the mean is the average of all 6, so adding all 6 numbers together and dividing by 6 will give you 3. Because of this we know the 6 numbers will have to add up to 18.
The median is the middle number, but we have an even number so the median is found by adding the 2 middle numbers and dividing by 2.
Because the mean is low, we can guess the first 2 numbers will be small, so let's try 1.
1 + 1 + _ + _ + _ + _
The remaining 4 numbers will have to add up to 16, and the next 2 numbers need to add up to 12. There would not be any possible combination where this would work. Now we know our first 2 numbers are too big.
Now we try 0.
0 + 0 + _ + _ + _ + _
Now our remaining 4 numbers neet to be 18, but the middle 2 need to add to 12 (so when we divide by 2 we get 6) so 0 is still too big!
-2 + -2 + _ + _ + _ + _
If we try -2 now the next 4 numbers need to add to 22, but that's still not going to work because 22-12 = 10 and the last 2 numbers have to be the same, or larger than the middle 2.
-3 + -3 + _ + _ + _ + _
With -3 then our total of the remaining 4 numbers needs to be 24 and 24-12 = 12 so this could be an option!
Our numbers could be:
-3, -3, 6, 6, 6, 6
Let's check:
-3 + -3 + 6 + 6 + 6 + 6 = 18 18/6 = 3 and our middle 2 numbers are 6 so our median would be 6.
If the numbers all have to be different we can come up with a different solution by making our first 2 numbers smaller.
-9, -5, 5, 7, 9, 11
Let's check
-9 + -5 + 5 + 7 + 9 + 11
-14 + 32 = 18 mean 18/6 = 3 median 5+7 = 12 and 12/2 = 6
So that could also work! There are actually many options that would be correct!
One of the set of numbers whose mean is 3 and median is 6 is 0, 1, 5, 7, 2 and 3.
What is Mean?Mean of a set of numbers is the average value of the numbers. Mean is calculated by taking the sum of the given numbers divided by the total number of numbers.
Let x₁, x₂, x₃, x₄, x₅ and x₆ be the six numbers.
We have mean = 3
⇒ (x₁ + x₂ + x₃ + x₄ + x₅ + x₆) / 6 = 3
⇒ x₁ + x₂ + x₃ + x₄ + x₅ + x₆ = 18
Median is the midpoint of the set of numbers arranged in ascending or descending orders.
If the number of set of numbers are odd, then median is the midpoint of the set and if the number of the set is even, then median is the average of the middle two elements.
Median = 6
Since there are 6 numbers here median = (x₃ + x₄) / 2
(x₃ + x₄) / 2 = 6
(x₃ + x₄) = 12
So x₁ + x₂ + x₅ + x₆ = 18 - 12 = 6
Lets just say x₁ = 0, x₂ = 1, x₅ = 2 and x₆ = 3, the sum of which equals 6.
Now, let x₃ = 5 and x₄ = 7, such that x₃ + x₄ = 12
So one of the set which satisfies the given conditions is x₁, x₂, x₃, x₄, x₅ and x₆ = 0, 1, 5, 7, 2 and 3 respectively.
Hence, one of the list of 6 numbers whose mean equals 3 and median equals 6 is 0, 1, 5, 7, 2 and 3.

What is the inverse of the function f (x) = x2 - 49?
Answer: [tex]f^{-1}(x)=\sqrt{x+49}[/tex]
Step-by-step explanation:
To find the inverse of a function, you want to switch the x with y and y with x. After that, you solve for y.
y=x²-49 [switch x with y and y with x]
x=y²-49 [add both sides by 49]
x+49=y² [square root both sides]
[tex]y=\sqrt{x+49}[/tex]
Now, we know that [tex]f^{-1}(x)=\sqrt{x+49}[/tex].
