Answer:
FOr the first one you can do:
y= -x +4
y= -x+2
y = -x
y= -x-2
y = x-4
Step-by-step explanation:
I'll do the second one in a different answer use these for now.
Answer: The net change would be -2.
Step-by-step explanation: The upward change of elevator is represented by positive sign while the downward change represented by negative sign.
Given, First the elevator goes up 15 floors, change = + 15, Then it goes 9 floors down, change = -9, Then it goes 11 floors up,Change = + 11, Finally, it goes 19 floor down, Change = - 19 So, the net change = sum of total changes = 15 - 9 + 11 - 19 = -2

-The perimeter is the length of the line if the whole rectangle was straightened out.
-a rectangle has 2 sets of 2 even sides. The top and bottom width would be equal and the two heights would be equal
Armed with these two facts we know the perimeter would be Side A + Side B + Side C + Side D
9.35 + 9.35 + 6.82 + 6.82 = ?
The actual formula for a rectangle or even a square is
2(length + width)
