Any complex number can be written in fallowing form:
Z = x + yi
When drawing complex numbers as point on x,y coordinate system we can use variables x and y to represent our coordinates in x y coordinate system.
Our complex number is:
Z = 3i which means
x = 0 and y = 3
x is real part of complex number and we draw it on x axis (real number axis) and y is imaginery part and we draw it on y axis (imaginery axis)
answer is point with coordinates (0,3) Graph 1
The change is the remaining money that is needed to take from the seller so a change of Umberto will be $6.62.
<h3>What is subtraction?</h3>
To subtract in mathematics is to take something away from a group or a number of objects.
The group's total number of items decreases or becomes lower when we subtract from it.
Given that,
Umberto buys a game for $7.89 and some batteries for $5.49.
Total money of buying = 7.89 + 5.49 = $13.38
Now he gives a $20 bill.
Remaining (change) = 20 - 13.38
⇒ $6.62
Hence "The change of Umberto will be $6.62".

Step-by-step explanation:
A negative divided by a negative is a positive.
Answer:
y = 7
Step-by-step explanation:
Given:
x1 = -2
y1 = 7
slope (m) = 0
y - y1 = m ( x - x1 )
y - 7 = 0 ( x - (-2) )
y - 7 = 0 ( x + 2 )
y - 7 = 0
y = 7
