Part A: Chose some value for x, that means any amount of books to print for example 100 books, so x=100
Replace x=100 in C(x) and solve:
C(100)=3.5*100+1200=1550
Part B: Replace C(x) by 1900 and solve for x from the given equation:
1900=3.5x+1200
3.5x=1900-1200
x=700/3.5= 200
Part C: the statement C(20)=1270 means that 1270 is the cost for printing 20 books.
Part E: C(40.5)=1341.75 I think this statement is incorrect given the context because x means number of books to print so this value must be an integer number.
It’s d, d is the right answer
|x - 3| - 1 = 5
x - 3 - 1 = 5
x - 4 = 5
x = 9
-(x - 3) - 1 = 5
-x + 3 - 1 = 5
-x + 2 = 5
-x = 3
x = - 3
x = -3 , 9 matched the answers on the number line
Answer is B) |x - 3| - 1 = 5
The equation to find the Volume of something is length*Width*height
therefore:
(I'm confused as to what <span>10/1/2 means so)
</span>
•on the assumption that 10/1/2 means 10 and a half - 10.5
then it would be - 15*10.5*2.5 = 393.75m^3
<span>•on the assumption that 10/1/2 means 10 divided by 1/2 then it would be:
</span>15*20*4 = 1200m^3
