<h3>Answer:</h3>
8 -2i
<h3>Explanation:</h3>
For purposes of addition and subtraction, "i" can be treated in the same way any variable would be. Like terms are added in the usual way.
... (5 -4i) + (3 +2i) = (5 +3) +(-4 +2)i = 8 -2i
Their total score is 8 - 2i.
Answer:
HOw to graph it
Step-by-step explanation:
Start at origin 0,0 make a point
go up 1 and over 2 make a point
connect with straight line
C would be the best deal.
A is $45 for 1 hr
D is $40 for 1 hr
C is $30 for nearly an hour...That is the best deal
Amounts of paint left over are:
Yellow: 1 1/7 - 3/4 = 32/28 - 21/28 = 11/28 gallon
Green: 1 1/8 - 3/4 = 9/8 - 6/8 = 3/8 gallon
Blue: 7/8 - 3/4 = 7/8 - 6/8 = 1/8 gallon
Add 11/28 gallon, 3/8 gallon and 1/8 gallon to answer this question.
we conclude that the cost of the camera at the photography store is P = $448.50

What is the cost of the camera at the photography store?</h3>
We know that the electronics store sells a certain camera for a total of $299.
Then, a photography store buys that camera, and re sells it, such that the old price, $299, is 2/3 of the new price.
If the new price is P, then we can write:
(2/3)*P = $299
This is just a linear equation that we need to solve for P, if we divide both sides by 2/3, we will get:
P = (3/2)*$299 = $448.50
In this way, we conclude that the cost of the camera at the photography store is P = $448.50
