Answer:
The change in the total cost for each book printed is $10
The cost to get started is $1250
Step-by-step explanation:
In the linear equation y = m x + b, where
- m is the rate of change per unit
- b is the initial amount (value y at x = 0)
∵ y represents the total cost of publishing a book in dollars
∵ x represents the number of copies of the book printed
∵ y = 1250 + 10 x
- Compare it with the linear equation y = m x + b
∴ m = 10
∴ b = 1250
∵ m = Δy/Δx
- That means m is the change in the total cost per book
∴ The change in the total cost for each book printed is $10
∵ b is value y at x = 0
- That means b is the cost to get started before print any book)
∴ The cost to get started is $1250
The single factor tested in an experiment is: THE VARIABLE.
The longest side in the figure measures 14 cm.
the side that is parallel to this side measures 9 cm.
if you are confused on how to look at this problem, look at it this way...
if we take away the side that measures 6 cm, we also need to take away 6 cm from the 10 cm side. if we do this, we end up with a 14 cm side and a 9 cm side with a missing (x) cm which we would add to the 9 cm side. look at it this way, if we put the 9 cm side and the (?) side on top of each other, it looks equal to the 14 cm side.
to solve for the length (in cm) of the missing side, I took 14 cm and subtracted 9 cm from it. when I did this, I got an answer of 5 cm. in conclusion, the missing side (?) is 5 cm.
the answers to the other two problems in your picture are:
5 cm
25 cm^2
125 cm^3
