The average cost when producing x items is found by dividing the cost function, c(x), by the number of items, x. when is the average cost less than 100, given the cost function is c(x) = 20x + 160?

When the produced item greater than 2, the average cost will be less than 100

Step-by-step explanation:

C(x) / x = 100 ... when x items produced and the cost is 100

(20x + 160) / x = 100

20x + 160 = 100x

80x = 160

x=2

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
