Answer :
n = 4
Step-by-step explanation:
5n + 34 = -2(1-7n)
first distribute
5n + 34 = -2(1) -2(-7n)
5n + 34 = -2+14n
-5n
+2
then get all of n to the same side
36 = 9n
isolate the variable
36/9 = 9n/9
4 = n
1) find the corresponding y values for when x = 0 and when x = 4,
when x = 0, y = 4
when x = 4, y = 4
the coordinates are (0,4) and (4,4)
2) to calculate the average rate of change, find the slope of the two points:
(0,4) (4,4)
(change in y) 4 - 4 = 0
(change in x) 4 - 0 = 4
0/4 = 0
the average rate of change is 0!
