Y-y1= m(x1-x2)
using this formula
the answer is d
because slope has to remain the same if its parallel
Answer:ggg
Step-by-step explanation:ggggg
Alright, lets get started.
In the question given that glacier receded 4 feet a day for a period of 25 days.
Which shows in 1 day, it recedes = 4 feet
means in 1 day, the height of the glacier gets shorter = 4 feet
So, in 25 days, the height of the glacier gets shorter = 4 * 25
So, in 25 days, the height of the glacier gets shorter
feet
It means the glacier will get 100 feet shorter at the end of the period of 25 days. : Answer
Hope it will help :)
Answer:880
Step-by-step explanation: They need to cover expense of $13200. If printing fee is $25 and they sell the books for $40 each, then that means when selling a book they cover expense of printing plus they earn $15 per book.
So if they earn $15 per book that means they have to sell 13200/15=880 books to break even.
If you want to solve this by using equation the this would look like this:
expenses: $13200 + $25x where x is number of books sold
earnings: $40x
Equation:
13200+25x=40x
13200=15x
x=880
