How is finding percent increase the same as finding percent decrease? How are they different


don't say u don't know or ill report

Answers

Answer 1

Answer:

They are not the same, but they do have there similarities.

Step-by-step explanation:

well what I mean is when you find the increase percent vs the decrease percent you get different answers. but they may end up the same answer depending on the question.

plz tell me if I i got it wrong thx :)

Answer 2

Answer:

So I have my own way of thinking:

So lets say a 25% increase of 60.

First what I would do is 25% x 60 = 15. THEN MAKE SURE YOU DON"T FORGET THIS STEP. You will have to do 60 + 15 = 75.

So that is for increase, you can do this with any numbers :).

So now lets say 25% decrease of 60.

First what I would do is 25% x 60 = 15 and then do 60 - 15 = 45. (Since we are decreasing)

So that is for the decrease, you can do this with any numbers :).

I HOPE THIS HELPS!!!!

Answer:

\(f^{-1}\left(f(576)\right)=\boxed{576}\)

\(f^{-1}(-7)+f(-7)=\boxed{13}\)

Step-by-step explanation:

The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).

Given table:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)

Inverse function:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)

If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).

Therefore:

\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)

The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.

The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.

Therefore:

\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

Answers

Answer:


D.

Step-by-step explanation:


According to the dot plot,


3 students spend 0.5 minutes brushing their teeth.


2 students spend 1.5 minutes brushing their teeth.


1 student spends 2.5 minutes brushing their teeth.


2 students spend 3.5 minutes brushing their teeth.


1 students spend 4 minutes brushing their teeth.



So, the number set will be: {0.5, 0.5, 0.5, 1.5, 1.5, 2.5, 3.5, 3.5, 4}


Median: The middle number in a set that is ordered from least to greatest.


In this example, the median is 1.5


Mean: The sum of all values divided by the number of values.

In this set there are 9 values so we’ll divide the sum by 9

In this example, the mean would be:

(0.5 + 0.5 + 0.5 + 1.5 + 1.5 + 2.5 + 3.5 + 3.5 + 4) ÷ 9

18 ÷ 9 = 2


If we compare the mean to the median we can see that the mean is greater because 2 > 1.5

When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.

When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

How to Interpret the Quadratic Graph?

The relative minimum or maximum of a graph is:

A relative maximum point is a point where the function changes direction from increasing to decreasing (making that point a "peak" in the graph).

A relative minimum point is a point where the function changes direction from decreasing to increasing (making that point a "bottom" in the graph).

Thus, the relative minimum of the graph is -4°C.

write a direct variation equation that relates 16 and 2

Add commeAnswer:

y = -4x

When x = 4, y = -16

When y = 20, x = -5

Step-by-step explanation:

First off, definitions: Direct variations refers to two variables being related with neither being the denominator of a fraction. (nothing along the lines of y = 1/x)

So, given that, I simply found what the ratio was between the two values. Something like buying gas at the gas station. The ratio between the gas you get and the money you pay is the price per gallon of gas. In this case, the proportion is -4 (-16 divided by 4).

Thus we have a relationship. For each y, you have negative four x's. Thus, y = -4x.

Finding the value of x when y = 20 simply requires plugging values in. Remember, a fundamental principle in all of Algebra is substitution. If two things are equal, they are interchangeable. So, if you saw "3 + 4" in a mathematical expression, you could simply erase it and write 7, so long as no other mathematical rules (multiplication before addition, for instance) interferes.

Thus, if y = 20, we can take our original equation and replace y with 20.

y = -4x       =>     20 = -4x

Then, simply solve for x, keeping in mind that when two items in math are written against each other, it means multiplication. Thus, we reverse the multiplication to division and divide both sides of the equation by -4.

20 / -4 = -5
