Answer:
5 + i
Step-by-step explanation:
Combine real part ans combine imaginary parts
2 + 3i + 3 - 2i = 2 + 3 + 3i - 2i
= 5 + i
Answer:
5 and 1i
Step-by-step explanation:
So you’re adding the following complex numbers: (2 + 3i) + (3 - 2i)
normally if you see a (-) in front of a number, that means it’s negative so we’re gonna think about this as -2i and positive 3.
so you’re gonna want to take the 2 regular while numbers (without the variable) and then add those together. they’re like numbers so neither of them have a variable, which means they can easily be added, but you can’t add a number like 7 to a number like 9h because there’s a variable.
Now that you’ve added the 2 and 3, you get 5 right? so now you’re gonna take the 3i and -2i, and add those together. since the number 3i is bigger than -2i, the ending number after you add those is gonna be positive, and it’s gonna be 1i.
now i’m not sure if you’re supposed to make an equation out of this but you’re answer will be 5 and 1i or 5 + 1i
also if you don’t want to put 1i, 1i is the same as just “i”. so you can put 5 + i :)

At a sale, coats were sold for 52% of their original price. If the coats originally cost
$200 each, how much did a coat cost on sale?
Help me please
Answer:
Answer is 104
Step-by-step explanation:
The selling price of the coat is $104.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Original price = $200
Selling price.
= 52% of $200
= 52/100 x 200
= $104
Thus,
$104 is the selling price of the coat.

m - 7 = -10
Answer:
m=-3
Step-by-step explanation:
m - 7 = -10
Ok so,
in order to get m by itself you just need to do the opposite of -7 which is +7 so you have to add 7 to both sides. On the left, both of the 7's cancel out and on the right -10 + 7 = -3. So, now it should look like this.
m=-3
To check you just need to plug in -3 into the question

The question was what fraction of all the songs are jazz. Therefore you need to find the common denominator which is 24. (8x3 =24).
Next you Multiply 5x3 which equals 15 and then you multiply 1x8 which equals 8. (We do this because you need to multiply your numerator by the same number you multiplied your denominator with)
Finally, you subtract 8/24 from 15/24 which equals 7. (15-8=7 [make sure you keep your denominator 24] )
Therefore your answer is 7/24

CAE it is 65˚
CBD it is 65˚
Step-by-step explanation:
x+40=3x-10
Move the 3x to the other side by subtracting by 3x on both sides
x-3x+40=3x-3x-10
The equation now looks like this:
-2x+40=-10
Move 40 to the other side by subtracting 40 both sides:
-2x+40-40=-10-40
-2x=-50
Divide by -2 on both sides:
-2x/-2=-50/-2
x=25
Since we found out what x is we can replace x in both CAE and CBD:
For CBD: 25+40 is 65
For CAE: 3(25)-10 is 65
Answer:
m∠CAE = 65, m∠CBD = 65
Step-by-step explanation:
Line CA is a transversal of lines AE and BD which are parallel, in this case corresponding angles are congruent. ∠CAE and ∠CBD are corresponding angles so you can make them equal to each other. x+40=3x-10 -> 2x=50 ->x=25. Now that we have x just plug it into the equations 25+40=65 which is m∠CBD. 3(25)-10=75-10=65 is m∠CAE

Which equation would best help solve the following problem? The height of a triangle is 5 m less than its base. The area of the triangle is 42 m² What is the length of the base?
Answer:
[tex]\boxed{\displaystyle 42=\frac{1}{2}x(x-5)}[/tex]
The second choice is correct
Step-by-step explanation:
Area of a Triangle
Given a triangle of base B and height H, the area is calculated by the formula:
[tex]\displaystyle A=\frac{1}{2}BH[/tex]
Let's call x=base of a triangle
Since the height of the triangle is 5 m less than the base:
x - 5 = height of the triangle.
Thus, the area is
[tex]\displaystyle A=\frac{1}{2}x(x-5)[/tex]
The value of the area is given as A=42 square meters, thus:
[tex]\boxed{\displaystyle 42=\frac{1}{2}x(x-5)}[/tex]
The second choice is correct

Here the question wants to find the range of function. Your answer is incorrect because you are confusing between range and domain.
What is domain?Domain is the set of all x-values. That means any values that are part of x are subset of domain itself. We can find domain two ways which are
Relation methodGraph methodBut we are not talking about domain as we are looking for the range of function.
What is range?Range is the set of all y-values. In the relations or ordered pairs (x, y). Our y is the range. Range can also be called Co-Domain or Output. But of course, we are not talking about finding range using relation method. We are going to find range by looking at the graph.
The range starts from minimum value to maximum value. If there is another point between minimum value and maximum, just ignore it.
Here is a diagram or easier way to understand.
[tex] \boxed{minimum} \Longrightarrow \boxed{maximum}[/tex]
From the graph, our minimum is -5 and our maximum is -1. Notice that there is another opened point at -2 which we are supposed to ignore. Because both minimum and maximum are closed dots. Hence, we use >= or <= only.
Therefore the solution should be
[tex] - 5 \leqslant y \leqslant - 1[/tex]
Answer[tex] - 5 \leqslant y \leqslant - 1[/tex]

The average value of a function f on [a, b]
always lies between f(a) and f(b). Justify your answer.
Answer:
False
Step-by-step explanation:
A parabola is a good example of proving this false, but more specifically is the graph of sin x on the interval [0, pi]. sin 0 = sin pi = 0, but the average value of sin x on this interval is greater than 0.
The average value of a function f on [a, b] always lies between f(a) and f(b) is false.
What is a function?A relation is a function if it has only One y-value for each x-value.
The average value of a function over an interval [a,b] is the total area over the length of the interval
A parabola is a good example of proving this false, but more specifically is the graph of sin x on the interval [0, pi].
sin 0 = sin pi = 0, but the average value of sin x on this interval is greater than 0.
So the average value of a function f on [a, b] always lies between f(a) and f(b) is false.
Hence, the average value of a function f on [a, b] always lies between f(a) and f(b) is false.
