Step-by-step explanation:
Hello,
First, of all, as x is positive we know that:

Let's simplify the expression:

Hope this helps.
Do not hesitate if you need further explanation.
Thank you
Answer:
It is not a function because it is not linear. If you place the coordinates in order of the x coordinates you can see that some of the y's are the same, and therefore do not have a pattern. This makes them non linear. The domain is -4≤x≤3, and the range is 0≤x≤4
Answer:
7 ft
Step-by-step explanation:
Let x be the shorter and y be the longer length
x + y = 10
x = 10 - y
4x = 2y - 2
4(10 - y) = 2y - 2
40 - 4y = 2y - 2
6y = 42
y = 7
Missing fact is 13 seats are empty
One endpoint at 1,3 and the midpoint at 3,5
Your answer would be to as two to each the x and y of the midpoint. so 5,7
