Yes, assuming that it is a straight line, the slope is the same everywhere, and therefore it would not matter at all what two points they selected, as long as they did all of their calculations correctly.
Answer:
The manager of a furniture factory finds that it costs $2400 to manufacture 50 chairs in one day and $4800 to produce 250 chairs in one day.
(a) First we will find m, that represents the rate of change of cost with respect to number of chairs:
so, m = 12 dollars per chair.
Let C be the cost and X be the number of chairs, the function can be written as (assuming that it is linear):
(b) Slope of the graph is m =12
Here slope represents that for every unit increase in number of chairs produced (X), the overall cost (C) will increase by 12 dollars.
Option - the cost (in dollars) of producing each additional chair.
(c) Y intercept is a dependent variable. It is $1800, when the value of independent variable (X) is 0. Also we can say that $1800 is the fixed cost that has to be paid irrespective of any chairs produced. If there is 0 production, still $1800 has to be paid.
Option - the cost (in dollars) of operating the factory daily.
Answer:
(x, y) → (x + 8, y + 4)
Step-by-step explanation:
Answer:
The cost of an orange is 21.5
Step-by-step explanation:
let orange be O and lemon be L
it becomes simultaneous Equations
2O+3L=64----1. x3
3O+4L=89----2. x2
6O+12L=192
6O+8L=178
subtracting
4L=14
L=7
put 7 for L in equ 1
2O+3(7)=64
2O+21=64
2O=64-21
2O=43
O=21.5
