In an inverse proportion two veriables are inversely proportional to each other.You can write the equation as P=n/x, and N is the constant of proportionality.In the equation the X increases and the P decreases.

Answer:

Whenever we talk about direct or inverse proportionality we talk about two variables

Suppose we have two variables x and y they are said to be in direct proportionality if they one vary same as the other

For eg:

x=3y

Here, whenever x increases y will increase and when x decreases y will decrease.

On the contrary, the two variables when have opposite behaviour

For eg:

x=3/y

Here, whenever x increases y will decrease and when x decreases y will increase.

Help ill give brainliest and a thank you and 5 star if correct

Temka [501]

Answer:

85%

Step-by-step explanation:

The discount is 15% which we can write as 0.15 and we multiply that by 30 to get the discount, which is $4.50. We subtract that from the original price; 30 to get $25.50 as the sale price. We want to find out what percent of 30 25.50 is, so we divide 25.50 and 30 to get 0.85. Multiply that by 100 to get 85%.

For the graphed function f(x) = -(5)* - 3 + 2, calculate the average rate of change from x = 3 to x = 4.

Ilia_Sergeevich [38]

Answer:

-4

Step-by-step explanation:

The average rate of change from x=a to x=b of f(x) is $\frac{f(b)-f(a)}{b-a}$

The given function is $f(x)=-5^{x-3}+2$ .

$f(4)=-5^{4-3}+2=-3$ .

$f(4)=-5^{3-3}+2=1$ .

The average rate of change from x=3 to x=4 is given by:

$\frac{f(4)-f(3)}{4-3}$

$\frac{-3-1}{4-3}=-4$

Is 7 1/8 grater or less than 7.025

aliina [53]

7 1/8 is greater than 7.025 because if you convert it into a decimal (8 * 7 = 56 + 1 = 57/8 =....) you get 7.125, which is obviously bigger (1>0)

Riley finished her 5k race in One-half hour. Darby finished the same race in Three-fifths hour. Which statement explains which g

Andrej [43]

Answer:

Riley did better than Darby because One-half < Three-fifths.

Step-by-step explanation:

The statement that explains which girl did better would be that

Riley did better than Darby because One-half < Three-fifths.

There are a total of 60 minutes in an hour, If we multiply each of these fractions by 60 minutes it would give us the exact number of minutes that each girl took to finish the race.

Riley: $\frac{1}{2}$ * 60 = 30 minutes

Darby: $\frac{3}{5}$ * 60 = 36 minutes

Therefore, we can see that it took Riley 6 minutes less than Darby to finish the race meaning that she had the better result.

What is the standard equation of the circle in the graph

ivanzaharov [21]

Answer:

option 1

Step-by-step explanation:

formula:(x-h)^(2)*(y-k)^(2)=r^2

well if you move the circle 3 units left h is (-3), plug it in, you get 3, so it is (x+3)^2*(y-k)^(2)=r^2

if you move the circle 2 units up, plug it in you get (-2), so it is

(x+3)^2*(y-2)^(2)=r^2

now, the radius is 3 (we can see from the graph) so radius ^2 is 9, thus

(x+3)^2*(y-2)^(2)=9

this is the answer, and the option that has it is answer is option 1
