Answer:
y = 8x + 4
Step-by-step explanation:
combine 1/2 and y:
-4x + y/2 = 2
add 4x to both sides:
+4x -4x + 1/2y = 2 +4x
mutiple both sides by 2 :
2 (y/2) = 2 (2 +4x)
simplify both sides:
y= 8x + 4
You can use substitution and solve y-x=2 for y which is y= x+ 2 and plug it into the y of the other equasion and you get x=5 y=7
Using derivatives, it is found that the best estimate of f '(2) based on this table of values is of 10.
The rate of change <u>from x = 0 to x = 2</u> is given by:

From <u>x = 2 to x = 4</u>, it is given by:

The average of these rates is:

Hence, the best estimate of f '(2) based on this table of values is of 10.
