Answer:
The correct answer is C) Reflection across the Y-axis.
Step-by-step explanation:
This is because only the x-coordinates changed. If these coordinates were reflected across both the x and y axis' the sign of both the x and y coordinates would have changed. When you reflect a point across the x axis, the y-coordinates change their sign. When you <u><em>reflect </em></u><u>a point across the y axis</u>, the <u>x-coordinates change</u> their sign.

Answer:
-2
Step-by-step explanation:
-3(2)+4
-6+4
-2
Alright, lets get started.
Suppose number of books Jim have = x
Sam has twice as many books as Jim. So,
Number of books Sam have = 2x
If Sam gives 12 books to Jim, they will have the same number of books.
When Sam gives 12 books, his remaining books will be 
When Jim gets 12 books from Sam, his books will be 
And as per given question, they both now have equal books, so

Adding 12 in both sides


Subtracting x from both sides


It means Jim has number of books = 24
So, Sam has numberof books = 
So, they have number of books together =

Answer:
This is 0.14 to the nearest hundredth
Step-by-step explanation:
Firstly we list the parameters;
Drive to school = 40
Take the bus = 50
Walk = 10
Sophomore = 30
Junior = 35
Senior = 35
Total number of students in sample is 100
Let W be the event that a student walked to school
So P(w) = 10/100 = 0.1
Let S be the event that a student is a senior
P(S) = 35/100 = 0.35
The probability we want to calculate can be said to be;
Probability that a student walked to school given that he is a senior
This can be represented and calculated as follows;
P( w| s) = P( w n s) / P(s)
w n s is the probability that a student walked to school and he is a senior
We need to know the number of seniors who walked to school
From the table, this is 5/100 = 0.05
So the Conditional probability is as follows;
P(W | S ) = 0.05/0.35 = 0.1429
To the nearest hundredth, that is 0.14
