Answer: c) 2x-5
We can represent two times micheal’s age as 2x, and 5 years younger would be you subtract 5
So the answer is 2x-5
1) function 2) not a function
the first one is a function because its y values are the same number (3), which means it is a horizontal line and horizontal lines are functions.
the second one is not a function because the coordinates cannot have different inputs but different outputs. each input must have only one output.
the coordinates for the second one are:
(2,5); (1,1); (1,2); (3,2)
and <u>a function cannot have two same x-coordinates</u>. it must pass the vertical line test which is a way to tell if something is a function or not. since the second graph does not pass the vertical line test, it is not a function
hope this helps :)
Answer:
"4.71" is the correct answer.
Step-by-step explanation:
As we know, 45 envelopes addressed in 2 hours then,
⇒ 
and, 45 in 3 hours,
⇒ 
Now by adding all together, we get
⇒ 
⇒ 
and multiply it by "4.71", we get
⇒ 
⇒ 
Round it "310".
So that "4.71" is the right answer.
60 subs
Because it’s 15 per 45 and 45 times 4 is 180 which means that in 3 hours or 180 minutes they sold 15 times 4 amount of subs and 15 times four is 60. Hope this helps. Sorry if the explanation isn’t that good
First lets start by making the denominators the same. I multiplied the 4 by 5 and 10 by 2.
-25/20 = x -14/20
Add 14/20 on both sides (do the opposite to cancel out and whatever you do to one side you need to do to the other.
You should get -11/20 = x
