Answer:
(a) 81 items
(b) 104 items
(c) 155 items
Step-by-step explanation:
Given:
The expression for the number of items produced by a new employee daily after 't' days on the job is given as:

(a) Number of days (t) = 5
Average number of items produced can be obtained by plugging in 5 for 't' in the above expression. This gives,

Therefore, nearly 81 items are produced after 5 days.
(b) Number of days (t) = 9
Average number of items produced can be obtained by plugging in 9 for 't' in the above expression. This gives,

Therefore, nearly 104 items are produced after 9 days.
(c) Number of days (t) = 30
Average number of items produced can be obtained by plugging in 30 for 't' in the above expression. This gives,

Therefore, nearly 155 items are produced after 30 days.
Answer:
[-7, 0]
Step-by-step explanation:
The range describes all values that y can take on. You may notica that the highest point of the graph has an y coordinate of 0 while the lowest has one of -7. Both values are included because they have filled in dots: this means the parenthesis are closed. So, the range would be: [-7, 0]. An alternate way to write this is
.
Answer:
x=3
Step-by-step explanation:
Answer:
x = -2
Step-by-step explanation:
5(-2x - 1) = -10x -5
-10x -5 - 5x + 2 = 27
-15x -3 = 27
+3 +3
-15x = 30
x = -2
