Answer:
Step-by-step explanation:
Let p represent the number of pens Nick sold. Then the revenue is ...
0.10p +0.05(1000 -p) = 74.50
0.05p = 24.50 . . . . . . eliminate parentheses, subtract 50
p = 490 . . . . . . . . . . . . multiply by 20
The number of pencils sold is then ...
pencils = 1000 -490 = 510
Nick's Printing Press sold 490 pens and 510 pencils.
I’m sorry but Where is the graph
<span>(-3 + 3i) + (-6 + 6i) =
= -3 + 3i + (-6) + 6i
= 3i + 6i + (-3) + (-6)
= 9i + (-9)
= 9i - 9

Do you mean scientific notation?
If so,
A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.
In order to write a number in scientific notation, I suggest you place the tip of your pencil right after the last digit in the number.
Then go backwards, counting each jump to the next number (this will be your exponent number).
You will go backwards until you reach your first NON-ZERO digit, which is where you will place the decimal point.
Multiply the decimal you now have by 10 (multiplying by 10 applies every time!) and then to the power of however many spaces you went back.
