Acompany that manufactures hiking boots produces 100 pairs of boots each day. the total daily production costs are $8,200, which include the cost of producing the boots plus $200 of fixed costs per day. which of the following equations represents the daily production cost based on the number of pairs of boots manufactured?
(let c(x) represent the daily production cost and x represent the number of pairs of boots manufactured.)
a.
c(x) = 80x + 200
b.
c(x) = 80x - 200
c.
c(x) = 82x
d.
c(x) = 90x + 200

step-by-step explanation: where's the phrase?

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

x = 12

y = 15
