Answer:
Step-by-step explanation:
The i is usually the square root of -1 which does not exist in the real number system.
The number given is a mixture of real and complex and is classified as complex.
The answer is C
Answer:
the answer is: C,Complex
Step-by-step explanation:
Complex Numbers
A Complex Numbers is a combination of a real number and an imaginary number in the form a + bi. The real part is a, and b is called the imaginary part.
Examples include 4 + 6i, 2 + (-5)i, (often written as 2 - 5i), 3.2 + 0i, and 0 + 2i.
Note the last two examples:
3.2 + 0i is just the real number 3.2. All real numbers are complex numbers with zero for the imaginary part.
0 + 2i is just the imaginary number 2i. All imaginary numbers are complex numbers with zero for the real part.

Ana is going to a craft fair where she'll sell her handmade scarfs. She has six scarf designs, and she's made 15 of each. She's paid $128 for the booth, and each scarf costs $9.80 to make. How much should she charge for each scarf if she wants to break even after selling a third of her scarves?
Answer:
$33.6667
Step-by-step explanation:
Given the following :
Number of Scarf designs = 6
Number of each made = 15
Total scarfs = (15 * 6) = 90
Cost:
Booth = $128
Production cost per scarf = $9.80
Total production cost = $9.80 * 90 = $882
Total cost = $128 + $882 = $1010
Break even = profit - loss = 0
One third of scarves = 1/3 * 90 = 30
This means he must cover for the total cost of $1010 after selling 30 scarves
Hence price per scarf will be :
$1010 / 30
= $33.6667
Can you please tell me the four types of algebraic expressions?
Answer:
MonomialPolynomialBinomialTrinomialMultinomial (these are the five types of algebraic expressions)What is the x-intercept of the slope of -2 and a y-intercept of 0, 6
Answer:
x- intercept = 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2 and c = 6 , thus
y = - 2x + 6 ← is the equation of the line
To find the x- intercept, let y = 0 in the equation and solve for x
- 2x + 6 = 0 ( subtract 6 from both sides )
- 2x = - 6 ( divide both sides by - 2 )
x = 3 ← x- intercept or (3, 0 )
Which of the lines graphed has a slope of 1 and a y-intercept of -3?
HELP!!!! Please it’s 6th grade!!
pls help me on this!
Answer:
5 2/3
Step-by-step explanation:
So because it is a mixed number that means you want to have a whole plus a fraction. You keep the 5 as the whole and because 2/3=.666666. You add them together making 5 2/3.
Can someone tell me the Term, variable, exponet, power and coefficient
I would appreciate it a lot
Write an equation and interpret the y-intercept.
You need $125 to buy an MP3 player. Your allowance is $5 per week and you earn $20 per lawn mowed
Write an equation that represents your weekly income in dollars for x lawns mowed. Interpret the y intercept . How many lawns do you need to mow to earn enough money in one week to buy the MP3 player?
Answer:
Answer in explanation
Step-by-step explanation:
The equation of a straight line can be represented in the form;
y = mx + c
where m is slope and c is y-intercept
In this particular case
y = 20x + 5
y is the weekly income, x is the number of lawns mowed
The y-intercept 5 is the amount earned in a week given they no lawn was mowed
In a case where y = 125
125 = 20x + 5
20x = 125-5
20x = 120
x = 120/20
x = 6
You need to mow 6 lawns to earn enough money in one week to buy the MP3 player

If x is direct proportional to y cube and x=32 when y=2
1. Find the value of x when y=6
2. Calculate the value of y when x=108
Answer:
1x=864,
2y=3
Step-by-step explanation:
y=6,x=?
if x is directly proportional to y^3 &if (when x=32, y is=2) we can understand that x=4y^3
1,x=4y^3
x=4(6^3)
x=4(216)
x=864
2,x=4y^3
108=4y^3
108/4=4y^3/4
27=y^3
√27=y
y=3
i think it is easy to understand,but if the answers are not clear you can ask me &i hope it helps you

Help!!! What is the equation of the following function? Show any work.
Answer:
[tex]y=-3(x+2)^2-3[/tex]
Step-by-step explanation:
Equation of the Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
The graph provided in the question, assumed as a parabola, has two clear points:
The vertex, located at (-2,-3)
The point (-1,-6)
Substituting the coordinates of the vertex, the equation of the function is:
[tex]y=a(x-(-2))^2-3[/tex]
[tex]y=a(x+2)^2-3[/tex]
The value of a will be determined by using the other point (-1,-6):
[tex]-6=a(-1+2)^2-3[/tex]
Operating:
[tex]-6=a(1)-3[/tex]
Solving:
a=-3
The equation of the graph is:
[tex]\boxed{y=-3(x+2)^2-3}[/tex]

Help i really need some help for this!!!! Complete the equation so that it has infinitely many solutions.
13(3−z)
Answer:
13(3 - z) = 13(3 - z)
13(3 - z) = 39 - 13z
Step-by-step explanation:
To make the equation have infinitely many solutions, when you simplify, the equation will become z = z
To make this happen, the equation has to be the same on either side of the equal sign. Here are the two options :
13(3 - z) = 13(3 - z)
13(3 - z) = 39 - 13z
