Answer:
c>6, since a negative coefficient reverses the sign
Step-by-step explanation:
7-c<1
-c<-6
c>6
Multiply all three numbers to get 560 yards cubed :))
You times it by one and then add the two zeros so your answer is 3,500
The average rate of change formula is
f(b) - f(a)
arc = ----------------
b-a
Here, a= -10 and b = 10
(10)^2 + 9(10) + 18 - [ (-10)^2 + 9(-10) + 18]
Here arc = --------------------------------------------------------------
10 - (-10)
10^2 and -(-10)^2 cancel. 18 - 18 cancel.
90 - (-90) 180
This leaves us with arc = ----------------- = ------------- = 9 (answer)
20 20
Answer:
