Dennis has a 3/7 yard long hair. she cuts 1/5. how much is left?

8/35 is your answer because

3 x 5/ 7 x 5       1 x 7/ 5 x 7

15/35 - 7/35

15 - 7/ 35

8/35

8/35

Step-by-step explanation:

Dennis has 3/7 yard long hair and cuts 1/5. So make 7 and 5, 35, because it is a number they are both divisible to. Then whatever you multiplied by do it to the numerators and then subtract.

(Note: if the denominator is the same with the other fraction don't subtract them only the numerators)

Step-by-step explanation:

* Lets explain how to solve the problem

- The form of the exponential function is , where

 a is the initial amount (x = 0) , b is the growth factor

- If b > 1 , then the function is exponential growth function

- If 0 < b < 1 , then the function is exponential decay function

- If the function translated horizontally by h units to the right , then

 the new function is

- If the function translated horizontally by h units to the left , then

 the new function is

- If the function translated vertically by k units up , then the new

 function is

- If the function translated vertically by k units down , then the new

 function is

* Lets solve the problem

∵ f(x) is an exponential function

∵ Points (0 , 1) , (1 , 10) , (2 , 100) belong to f(x)

- g(x) is the image of f(x) after translation

∵ Points (3 , 1) , (4 , 10) , (5 , 100) belong to g(x)

∵ point (0 , 1) on f(x) becomes (3 , 1) on g(x)

∵ point (1 , 10) on f(x) becomes (4 , 10) on g(x)

∵ point (2 , 100) on f(x) becomes (5 , 100) in g(x)

∵ All the y-coordinates of the points on the function f(x) are the same

 with the y-coordinates of the points on the function g(x)

∴ There is no vertical translation

∵ The x-coordinates of the points on the function f(x) are added by

   3 units to give the x-coordinates of the points on the function g(x)

∴ f(x) is translated 3 units to the right

∵

∴
