Answer:
41Step-by-step explanation:
Given a complex number z = x+iy, the modulus of the complex number is expressed as |z| = √x²+y².
Given the complex number z = 9+40i
The modulus of the complex number z will be expressed as;
|z| = √9²+40²
|z| = √81+1600
|z| = √1681
|z| = 41
Hence the modulus of the complex number |9+40i| is 41. Note that a complex number will return a real value.
Answer:
|9+40i| = 41
|-10+24i| = 26
He should have used 13 instead of 13i.

describe how you can tell by lookin at a graph of a function which variable is the input variable and which is the output variable
Answer:
The output variable will be on the y-axis, the input variable will be on the x-axis.
Step-by-step explanation:
To create a function, we must an equation in the form of
[tex]Y(x) = kx + b[/tex]
The x-axis of a graph will be what we change in the function. We will get a certain value ([tex]Y(x)[/tex]) that changes when the right side of the function changes. This means that the input of the function will be [tex]x[/tex].
The y-axis of a graph will be what the x-axis makes. In this case, it's [tex]Y(x)[/tex]. This is the output of the graph after given the input. This means the output is [tex]Y(x)[/tex].

Answer:
6
Step-by-step explanation:
if the 10% is equal to 3 then 20% is
10/3 = 20/x cross multiply
60 = 10x

midpoint of AB with A(-3, 5) and B(1, 7).
Answer:
(- 1, 6 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ ) ]
Here (x₁, y₁ ) = A(- 3, 5) and (x₂, y₂ ) = B(1, 7) , thus
midpoint = [ [tex]\frac{1}{2}[/tex] (- 3 + 1 ), [tex]\frac{1}{2}[/tex] (5 + 7) ] = (- 1, 6 )

What is the equation of a line that is perpendicular to y = -1/5x + 1 and passes through point (0, -2)?
Answer:
y = 5x - 2
Step-by-step explanation:
The slope will be 5, because that is the opposite reciprocal of the original slope, -1/5
Then, plug the slope and the given point into y = mx + b to find b:
y = mx + b
-2 = 5(0) + b
-2 = 0 + b
-2 = b
Then, plug the y-intercept and the slope into the equation:
y = 5x - 2 will be the equation

Choose the number in which the digit 2 is ten times greater than the digit 2 in 426.
Answer: 237
Step-by-step explanation:
Ok we can write 426 as:
400 + 20 + 6
Then the 2 in 426 is in the place of the tens and represents a 20.
If we want a number with a 2 that is 10 times greater than 20, we have that:
10*20 = 200.
Then we should find a number with a 2 in the hundreds place, an example can be:
237
where we can write this number as:
237 = 200 + 30 + 7
and the 2 is in the hundreds place.

Find the value of (x) 2x + 2(-3x-5)=26
Answer:
x = -9
Step-by-step explanation:
Solve for x:
2 (-3 x - 5) + 2 x = 26
2 (-3 x - 5) = -6 x - 10:
2 x + -6 x - 10 = 26
2 x - 6 x = -4 x:
-4 x - 10 = 26
Add 10 to both sides:
(10 - 10) - 4 x = 10 + 26
10 - 10 = 0:
-4 x = 26 + 10
26 + 10 = 36:
-4 x = 36
Divide both sides of -4 x = 36 by -4:
(-4 x)/(-4) = 36/(-4)
(-4)/(-4) = 1:
x = 36/(-4)
The gcd of 36 and -4 is 4, so 36/(-4) = (4×9)/(4 (-1)) = 4/4×9/(-1) = 9/(-1):
x = 9/(-1)
Multiply numerator and denominator of 9/(-1) by -1:
Answer: x = -9

The two lines shown intersect at the point (a,b). Find ab. Each unit square in the grid represents a distance of 1.
Answer:
(9/5, 8/5)
Step-by-step explanation:
First you want to find the equations of the lines. One line is y = 2x - 2 and the other line is y = 1/3x + 1. Then you want to find the x and y that both work in the two equations.
y = 2x - 2
y = 1/3x + 1
Then you do 2x - 2 = 1/3x + 1
Then you do some maths and you get 9/5, and 8/5
preform the indicated opperation 5 1/6 - -2 2/3
Answer:
7 5/6
Step-by-step explanation:
Since you're a subtracting a negative, ti cancels each other out and ends up in addition. So it's 5 1/6+2 2/3. And to add fractions the denominators must be the same.
Thus, you multiple 2/3 * 2= 4/6. So 5+2=7.
And 1/6+4/6=5/6.
Therefore the answers is 7 5/6.
Which of the following contains examples of ALLITERATION? Question 2 options: “We real cool. We left school.” “We lurk late. We strike straight.” “My soul has grown deep like the rivers.” “I’ve known rivers; ancient, dusky rivers.”
Answer:
We lurk late. We stike straight.
Step-by-step explanation:
Alliteration is the repetition of the beginning sounds ir letters of words.
Ex: Lucy is lazily laughing.
An item has a listed price of $80. If the sales tax rate is 7%, how much is the sales tax (in dollars)
Multiplying a listed price by the percent can get you the sales tax, and then you can add.
[tex]80*0.07=5.6[/tex]
(0.07 is 7% converted into a decimal)
[tex]80+5.6=85.60[/tex]
So the item is $85.60 after sales tax.
You may also notice that multiplying the listed price by 1.07 will get you the same answer, without the need to add the sales tax.
[tex]80*1.07=85.60[/tex]
Hope this helps.
頑張って!

A term is an expression is a set of constants, variables, and exponents, while the coefficient of a term is the numerical value present in the term.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
A term in an expression is a set of constant or numerical values, variables, and exponents. Each term of an expression is differentiated from others by a mathematical operation. For example, in the expression 2x²+6x-5, 2x², 6x, and -5 all three are terms and it is differentiated from others by the '+' and '-' operators.
The coefficient of a term is the numerical value present in the term. Let's understand this with the similar example above.
In term 2x², 2 is the coefficient.
In term 6x, 6 is the coefficient.
Hence, a term is an expression is a set of constants, variables, and exponents, while the coefficient of a term is the numerical value present in the term.

sarah is drawing a parallelogram abcd on a coordinate plane. the parallelogram has the coordinates A(-7,5) B(6,5) and D(-9,-2). which of the following coordinates should sarah use for point c?
A. (6,-3)
B. (4,-5)
C. (4,-2)
D. (6,3)
Answer:
(4,-2)
Step-by-step explanation:
Okay, I figured out the answer...
You need to use the [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{2}}[/tex] formula.
We know that AB is parallel to CD....(so whatever answer ad is, then cd will have that same answer).
We also know that AD is parallel to BC...(so whatever answer ad is, then bc will be the same).
So we need to find AB, CD, AD, BC. We have to do CD and BC later because we don't have the c.
Find AB: [tex]\frac{5-5}{6-(-7)}[/tex]= [tex]\frac{0}{13}[/tex]= 0
Find AD: [tex]\frac{-2-5}{-9-(-7)}[/tex] = [tex]\frac{-7}{-2}[/tex]
So now that we have the basic ones, we know that AB is parallel to CD. Therefore CD should have the same slope of 0/13 or 0. SO we need to find numbers that combine with the x and y of AB. When they do combine, they should give a fraction of 0/13.
Find CD: [tex]\frac{-2+2}{-9-4}[/tex] ( we already had the -2...what number adds to -2 to make it zero?...positive 2.....Then, we already had -9 from the D coordinates. So what # adds/subs to -9 to make it 13 or -13...well 4 does. Remember to put the correct signs (-+) in the equation. Our answer is 4,-2). If we had to use positive two, then we take the opposite for our answer. We used -4, so we take the opposite for our answer. Then later on, you can plug in (4,-2) into BC to see if you were to get the slope of -7/-2. which you do.

Step-by-step explanation:
It is given that Sally takes [tex]2\dfrac{5}{6}[/tex] minutes to drive from her home to the local shopping center.
[tex]2\dfrac{5}{6}=\dfrac{2(6)+5}{6}[/tex]
