Answer:
Average rate of change = 2
Step-by-step explanation:
Find the average rate of change for f(x) = x^2 − 3x − 10 from x = −5 to x = 10.
f(-5) = (-5)^2 − 3(-5) − 10 = 25 + 15 - 10 = 30
f(10) = 10^2 − 3(10) − 10 = 100 - 30 - 10 = 60
Average rate of change:
f(10) - f(-5) 60 - 30 30
-------------------- = ------------------------------- = ----------------------- = 2
10 - (-5) 15 15
4n-2n+4=-1+17
2n+4=-1+17
-1+17=16
2n+4=16
Move + 4 to the other side. Sign changes from +4 to -4
2n+4-4=16-4
2n=12
Divide by 2 for 2n and 12
2n/2=12/2
n=6
Check answer by using substitution method
4(6)-2(6)+4=16
24-12+4=16
12+4=16
16=16
Answer : n=6
