8b + 8 - 4b - 3
Combine like terms:-
(8-4)b + 8 - 3
4b + 8 - 3
4b + 5
Answer:
Step-by-step explanation:
n = 8
c(n) = -6+5(n - 1)
c(8) = -6+5(8 - 1)
c(8) = -6+5( 7)
c(8) = -6+5(7)
c(8) = -6+35
c(8) = 29

Answer:
The total number of unbroken / working slots
Step-by-step explanation:
Given that Devin's DVD case has 3 rows of slots, but 5 slots are broken
Also given that the number of slots in a row is x
1 row has x slots
3 rows has y slots
on cross multiplication we get y = 3x
ie there are a total of 3x slots in the 3 rows
Given that out of these 3x slots 5 . of the slots are broken
Therefore the total number of working slots = total number of slots - number of slots which are broken
total number of working slots are = 3x - 5
Therefore the given expression is the number of working / good slots
Answer: 14
Square both sides, getting you
2x-3=25
Add 3 to both sides
2x=28
Divide both sides by 2
x=14
Answer:
-0.5
Step-by-step explanation:
The average rate of change from a to b:
[f(b) - f(a)]/(b - a)
Look in the graph for the function values at x = -3 and x = 0.
f(-3) = 2
f(0) = 0.5
average rate of change =
= [f(-3) - f(0)]/(-3 - 0)
= [2 - 0.5]/(-3)
= 1.5/(-3)
= -0.5
