if you decrease by a given percent and then increase by the same percent, will you be back where you started? how do you know
quester [9]

Lets pick a random number, like 50. Lets decrease and increase it by 50%. After the decrease, you will get 25, but when you increase it by 50%, it's only 37.5. No, because when you decrease it, you have a smaller base, so it increases less than it decreases. 50% of 100 is 50, but 50% of 50 is 25. You can see there is a significant difference.

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number? x = –1 and x =
andrey2020 [161]

we have

f(x)=x^{2}-2x-3

Find the roots

Equate the function to zero

x^{2}-2x-3=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

x^{2}-2x=3

Complete the square. Remember to balance the equation by adding the same constants to each side.

x^{2}-2x+1=3+1

x^{2}-2x+1=4

Rewrite as perfect squares

(x-1)^{2}=4

Square root both sides

(x-1)=(+/-)2

x=1(+/-)2

x=1+2=3

x=1-2=-1

therefore

<u>the answer is</u>

x=3

(will give brainly) orde the values on the cards below in ascending order
VMariaS [17]

Answer:

Step-by-step explanation:

Set 1

first of all we have to look at the negative numbers:

-99% = -0,99

-√80 = is almost 9

so :

-9,(9) ; -√80 ; -99%

then the positive numbers:

19% = 0,19

√9 = 3

1/9 = 0,11...

so

1/9 ; 19% ; √9

final answer:

-9,(9) ; -√80 ; -99% ; 1/9 ; 19%, √9

Set 2

descending order = from greatest to least

In this case we have to look at first at positive numbers

2/3 = 0,6

√23 = 4,...

20/3 = 6,...

23% = 0,23

so

20/3 ; √23 ; 2/3 ; 23%

negative numbers

-√34 = -5,...

so :

-4,(3) ; -√34

final answer:

20/3 ; √23 ; 2/3 ; 23% ; -4,(3) ; -√34
