Answer:
-26/18 and -39/27
Step-by-step explanation:
-13/9 x 2/2 = -26/18
-13/9 x 3/3 = -39/27

Increase means “go up” which is another way to say addition
Twice means “two times” or “doubled”
A number would be a variable since it’s unknown

2•3=6 +2=8 8 squared is 8•8 which is 64. This problem is quite simple.
Answer:
X=3
Step-by-step explanation:
Step 1: Find the square root of 64
since there is an exponent of 2 around your paranthesis, you must get rid of that first, by finding the square root of the first part of the equation and 64. then you will have (2x+2)=8
Step 2: Subtract 2
next subtract 2 from both sides of the equation, and you will have 2x=6
Step 3: divide by 2
lastly, divide each side by 2. you will get x=3

what if there happened to be 1 person at the gym,
therfor you conclude that 100% of people at school exercise?
rediculus
1. no, becuse yo only asked peple at gym who are probaly exercising or pretenitng to exercise or showing off
2. yes, at the doors of the school or the school cafeteria or where there is a mixed group of people, the more the better, if you can survey the entire school, great
3. that is an either or situation, also people don't like to be called a couch potato so theere will be some people who will lie and say they exercise every day and there will be some peple wo don't want to answer and there will be some who will think you are insulting them and punch you
you will have biased results since you changed the question to the extermes

Final answer:
The scale factor of the dilation is calculated by dividing the length of the line after dilation by the length of the initial line. The length of a line is calculated using the distance formula. The center of dilation is the point from which the shape scales, but we can't determine its location without more information.
Explanation:
To find the scale factor of a dilation in a two-dimensional plane, we divide the length of the line after dilation by the length of the initial line. The length of a line can be calculated using the distance formula which is √[(x₂ - x₁)² + (y₂ - y₁)²].
For AB, the distance will be √[(5 - 9)² + (-4 - 4)²] = √[(-4)² + (-8)²] which equals √80. For A'B', the distance will be √(3 - 6)² + (-3 - 3)² = √[(-3)² + (-6)²] which equals √45. The scale factor (k) of the dilation is the ratio of these distances, so k = √45 / √80 which simplifies to √(9/16) or 3/4.
Unfortunately, without more information, such as a fixed point in the original shape, we can't determine the exact location of the center of dilation. But, conceptually, it's the point that the shape is scaling towards or away from during the dilation.
