Answer:
m=rise/sun=y2-y1 x2-x1
Step-by-step explanation:
m=slope (x1, y1) coordinates of first point in the line
(x2, y2) coordinates of second point in line.
Answer:15
Step-by-step explanation:
Given
Craftsman sell 10 Jewelry set for $500 each
For each additional set he will decrease the price by $ 25
Suppose he sells n set over 10 set
Earning
Earning
differentiate to get the maximum value
Equate to get maximum value
Thus must sell 5 extra set to maximize its earnings.

If five mechanical pencils cost #4.27.
we need to find the scale factor used to calculate the cost of 54 pencils
We are given with 5 pencils
We need to find the scale factor for 54 pencils
we need to find out what multiply with 5 to get 54
For that we divide 54 by 5
so scale factor is 10.8
5 times 10.8 = 54
We multiply the scale factor 10.8 by cost of 5 pencils to find the cost of 54 pencils
10.8 * 4.27 = 46.116 = $46.12
the scale factor 10.8 is used to calculate the cost of 54 pencils
