Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x - 9 ← is in slope- intercept form
with slope m =
• Parallel lines have equal slopes, hence
y = x + c ← is the partial equation of the parallel line.
To find c substitute (- 8, - 18) into the partial equation
- 18 = - 6 + c ⇒ c = - 18 + 6 = - 12
y = x - 12 ← equation of parallel line
If we place the books using their width on the length of the book shelf then
each book occupy the length : 9.3* 10^-2 meter on the length of the book shelf .Here width of book and length of book shelf is in same unit , that is meter . so we do not have to do any work with changing the unit .
number of books = length of the book shelf divide by width of the book
That is : 1.865 x 10 ^1 divide by 9.3x 10^-2 = 200.53
Because number of books placed can not be a decimal number so we would place only 200 books
Answer :200 books . Option A is correct .
Answer:
Due to the high number of deaths and the subsequent population reduction, the merchants - and tradespeople in general - saw a decrease in the sales of their merchandise. Once the number of infected people by the plague reduced was reduced at the end of the Fifteenth Century, the population grew exponentially, thus creating a higher demand for services and goods.
