The first (and most typical) way to find distance of two points is by using the distance formula.
One alternative is the Manhattan metric, also called the taxicab metric. This option is much more complicated, and rarely used in high school math. d(x,y)=∑i|xi-yi|
The value of x=1
Step-by-step explanation:
Given the equations as :
-2x + y= 8
5x - y= -5 ------adding the equations
---------------------
3x = 3 -------dividing both sides by 3
x = 1

Hi there!
Your question is:
For 8 days of very hot weather, the water level in a lake dropped 3 inches per day. on the ninth day, storms raised the level 6 inches. Write and find the value of an expression for the change in the water level of the lake during these 9 days.Here is my answer:
If the water level drops 3 inches per day for eight days, it would have gone down a total of 24 inches over those 8 days. Now, the rain storm added 9 inches of water back to the lake. 24 - 9 = 15.
Summary:
8 x 3 = 24
-24 + 9 = -15.
I hope this helped you, and dont hesitate to ask me for anymore help if you need it.
Stay Crazzzzzy! xD
If the line is linear and passes through the point (0,0) then the function is proportional.
3y = -2x + 6 is linear but does not pass through the point (0,0).
3y = -2x + 6 is nonproportional.
