1 answer:
517284 books have been sold to date.
Step-by-step explanation:
Given,
Copies sold in first month = 41900
This represents 8.1% of copies sold to date.
Let,
x be the number of copies that have been sold to date.
8.1% of x = 41900
Dividing both sides by 0.081
Rounding off to nearest whole number
x = 517284
517284 books have been sold to date.

Answer: slope = -1,5
Step-by-step explanation:
We can use slope formula to find the slope of a line that passes through two points (x₁ , y₁) and (x₂ , y₂)
m = ∆y/∆x = (y₂ - y₁)/(x₂ - x₁)
Given points are: p(x₁ , y₁) = (5 , −9) and q(x₂ , y₂) = (−5 , 6)
Substituting these two known points in the slope formula, we have:
m = (6-(-9))/(-5-5) = 15/-10 = -1,5
Therefore, the slope of this line = -1,5
Answer: slope = -1,5
