= (5 - 9i) + (-4 + 7i) - (14 - 3i)
Combine like terms; two negatives make a positive when you remove parentheses
= (5 + -4 + -14) + (-9i + 7i + 3i)
= -13 + 1i or -13 + i
ANSWER: -13 + i (first choice)
Hope this helps! :)
Answer:
A. 14040 cubic inches
B. 61 gallons
Step-by-step explanation:
The volume of a cuboid is given by the formula ...
V = LWH
__
<h3>A.</h3>
One yard is 36 inches, so 1 yard 3 inches is 36 +3 = 39 inches.
One foot is 12 inches, so 1.5 ft = 1.5×12 = 18 inches.
The volume of the fish tank is ...
V = (39 in)(18 in)(20 in) = 14,040 in³
The volume is 14,040 cubic inches.
__
<h3>B.</h3>
One gallon is 16 cups, so 976 cups is 976/16 = 61 gallons.
976 cups equals 61 gallons.
_____
<em>Additional comment</em>
One gallon is 231 cubic inches, so the volume of the tank is actually about 972 cups, or 60.8 gallons.
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
Hey there,

B should equal 10. you just have to figure out what would get you b and then you can figure it out from there!!
