Answer:
All are correct
Step-by-step explanation:
If Friend A gives 145 and Friend C gives 245 they already have a total of $390 out of the $700. So the missing amount is 310, half that for both friends and get 155, so the last 2 could both pay 155. No matter which way you put the number you will get the same answer. And as the communitive property states "The numbers on which we operate can be moved or swapped from their position without making any difference to the answer." and all of the answer choices apply to that statment.
Answer:
The function is odd because it is symmetric about the origin.
Step-by-step explanation:
we know that
A function f(x) is even when
f(x)=f(-x) ----> the function is symmetry about the y-axis
A function is odd when
-f(x)=f(-x) ---> the function is symmetry about the origin
In this problem we have
f(x)=-5x
<em>Verify if the function is even</em>
For x=1 ----> f(1)=-5(1)=-5
For x=-1 ---> f(-1)=-5(-1)=5
so
f(x) is not equal to f(-x)
therefore The function is not even
<em>Verify if the function is odd</em>
we have
f(1)=-5
f(-1)=5
so
-f(1) is equal to f(-1)
-f(x)=f(-x)
therefore
The function is odd because it is symmetric about the origin.

Answer:
substitution property of equality
Step-by-step explanation:
im assuming this means that you substitute x's value of 2 into the equation y=3x2-11. i'm guessing that it's meant to be 3x2, instead of 3.2. i hope this makes sense, and i hope i answered it as you needed!
