To answer this you need to make simple thought experiment. Since the number of sales after time passes cannot go negative (note that rate at which copies are sold can drop over time but total number cannot) that means that you are adding number of sales at first hour and during first hour.
first option cannot be the answer because you are subtracting 100 copies to total number of sold copies which is not logical.
The answer is D) s(x) = 100 + 12(x-1)
after 1 hour (if you replace x with 1 in equation above) you will get 100 copies which matches conditions in the text.
The edge represented by EA is the edge skewed to edge FG. Skew lines are non-intersecting lines in space. These lines are neither parallel nor they form right angles.
Answer: -4 becus it is less then 2, which means it is steep
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
1. Add the costs together 10.98+13.95+22.56=47.49
2. To get an average, divide by the amount of numbers you added together. We added 3 numbers together (10.98+13.95+22.56) so we divide by 3.
47.49/3=15.83
The option closest to our number is D so we round up.
$15.83->$20
Have a good day.
first make them into improper fractions 124/15 and 54/15 then subtract so it would be 70/15 then turn it into a mixed number 4 10/15
