Answer:13(4200+6*10-)
Step-by-step explanation:
Answer:
D -13/35 ( negative 13/35 )
Step-by-step explanation:
4/5 + x = 3/7
Convert to equivalent fractions with a common denominator:
28/35 + x = 15/35
Subtract 28/35 from both sides
x = - 13/35

4x+y=10
y=10-4x
----------
Now y=f(x), so:
f(x)=10-4x
Since we are already given the equation, we can already solve for the given problems above. Let us start with part 2 so we can easily answer part 1.
Part 2: the cost to get started before any books are printed. Using the equation, x = 0. So, y =1250+25(0)
y= 1250
So the cost to get started before any books are printed is 1250.
Now, to part 1, let us say, only 1 book is printed. So x=1
y = 1250 +25(1)
y= 1250 +25
y = 1275
So, for 1 book is 1275, and no book is 1250. This gives us the answer that the change in the total cost for each book printed would be $25. Hope this is the answer that you are looking for.
