The answer is b. (-2,2)
Since it is a dilation of 2, multiply each number by 2.
-1*2=-2
1*2=2
So after the dilation, it would be (-2,2)
Et y represent the number of students in the group who are not members. You can write an expression for y in terms of x from the information given. What do you know? The total number of students = 19 x + y = 19 which gives you y = 19 - x OR you also know the total cost is 209 and you can use that and the cost of the two types of tickets to obtain an expression for y in terms of x.
Answer:
It's a function because when you simplify it becomes y=-x-3. the only reason it wouldn't be a function would be if the equation were to be x = a random number that is not a variable. The equation would not pass the vertical line test which is the requirement to see if an equation is a function.
Simply put, it's a function.
When building a Venn Diagram, I always start from the area with the most overlap to the areas of least overlap. Once you have placed the 3 in the middle, you have counted those people, and therefore you must subtract them from the other surveys. Example: since there are 3 people that like all three subjects, now only have 5 students that like just math and English instead of 8.
Therefore:
A) 36 Students were in the survey
*Add all the numbers within the Venn diagram up. Overlapping doesn't matter because no one is double counted.
B) 6 People liked only Math
*Can't touch any other circle but Math
C) 20 Students liked English and math, but not history
*You add 9+5+6, since these bubbles are not overlapping with history.

The volume of a rectangular prism is represented by the following equation:

where w is the width , l is the length, and h is the height
Replace
with
since the length is tripled


From this, we see that this new volume is 3x larger than the original. Thus, the volume is tripled when its length is tripled.
Let me know if you need any clarifications, thanks!
