We are given with the formula
p = 200k - 500
a) The constraint for this formula is obtained from the idea that the profit must be positive
200k - 500 > 0
k > 500/200
k > 2.5
b) To make 14000 profit
14000 = 200k - 500
k = 72.5 or 73 knives must be sold
Answer:
+65
Step-by-step explanation:
If you distribute negative with negative it gives you positive
The equation of line perpendicular to given line through (-6,7) is:

Further explanation:
Given equation of line is:

The co-efficient of x is the slope of given line.
Let m1 be the slope of given line
and
m2 be the slope of line perpendicular to given line
Then

Product of slopes of perpendicular lines is -1

The equation of new line can be written as:

Putting m2

To find the value of b, we will put (-6,7) in equation

Putting the values of b and m in general equation
