Step-by-step explanation:
Let z = 5 – 9i and w = 6 + i.
Which expression shows the first step in finding the quotient of StartFraction z Over w EndFraction ?
StartFraction 5 minus 9 I Over 6 + I EndFraction times StartFraction 6 minus I Over 6 minus I EndFraction
StartFraction 5 minus 9 I Over 6 + I EndFraction times StartFraction 6 + I Over 6 + I EndFraction
StartFraction 5 minus 9 I Over 6 + I EndFraction times StartFraction 5 minus I Over 5 minus I EndFraction
StartFraction 5 minus 9 I Over 6 + I EndFraction times StartFraction 5 + I Over 5 + I EndFraction
Given:
[tex]z=5-9i[/tex]
[tex]w=6+i[/tex]
To find:
The expression that shows the first step in finding the quotient of [tex]\dfrac{z}{w}[/tex].
Solution:
According to the question,
[tex]\dfrac{z}{w}=\dfrac{5-9i}{6+i}[/tex]
First, we need to multiply and divide the conjugate of denominator, i.e., 6-i, to find the quotient.
[tex]\dfrac{z}{w}=\dfrac{5-9i}{6+i}\times \dfrac{6-i}{6-i}[/tex]
Therefore, the correct option is A.

The absolute value of opposite numbers is the same?
True or False?
Why or Why not
Answer:
false, it's the opposite so its doesn't have the same amount, negative or positive.
True.
The absolute value of opposite numbers is the same as the number because the absolute value is always positive.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number = x
The opposite of x is -x.
Now,
The absolute value of -x.
= |-x|
= x
We are getting the number back.
Thus,

The sides of a right triangle are (x-5) (x+2) (x+3). solve for x.
Can someone pls help me on this problem
Answer:
x = 10.
Step-by-step explanation:
The longest side , the hypotenuse = x + 3 because the lengths of the sides are positive.
So, by Pythagoras:
(x + 3)^2 = (x - 5)^2 + (x + 2)^2
x^2 + 6x + 9 = x^2 - 10x + 25 + x^2 + 4x + 4
0 = 2x^2 - x^2 - 10x + 4x - 6x + 29 - 9
x^2 - 12x + 20 = 0
(x - 10)(x - 2) = 0
x = 2, 10.
x cannot be 2 because that would make one side = 2- 5 = -3 so the answer is x = 10.

Solve the following equation by combining like terms:
x +x +2 +3x- 6 = 31
Answer:
x=7
Step-by-step explanation:
We want to get the variable "x" alone to get our answer. So.
1. combine like terms
x+x+2+3x-6=31
like terms in equation: (left side)
x, x, 3x= 5x (equation: x+x+3x)
2, -6= -4 (equation: 2-6)
so, this is what the equation would look like with our new answers:
5x-4=31
2. add 4 to both sides
5x-4+4=31+4
(on left side of equation, the -4 and +4 cancel each other out, leaving the 5x alone)
5x=35
3. divide 5 from both sides, to get the "x" alone
5x/5=35/5
so, our answer would be:
x=7

Step-by-step explanation:
We simplify it into 3 1/6 - 1 5/6.
Since 5 cannot subtract from 1, we convert 3 1/6 into 2 7/6 because it is equivalent to 3 1/6, and subtract 1 5/6 from that fraction to get 1 1/3.
If triangle STR ~ triangle PTQ, find QT
Answer:
QT = 45
Step-by-step explanation:
ST = 65
SP = 26
RQ = 30
QT = 4x - 3
Given that ∆STR is similar to ∆PTQ, therefore:
[tex] \frac{ST}{PT} = \frac{RT}{QT} [/tex]
Plug in the values
[tex] \frac{65}{65 - 26} = \frac{30 + (4x - 3)}{4x - 3} [/tex]
Solve for x
[tex] \frac{65}{39} = \frac{30 + 4x - 3)}{4x - 3} [/tex]
[tex] \frac{5}{3} = \frac{27 + 4x}{4x - 3} [/tex]
Cross multiply
[tex] 5(4x - 3) = 3(27 + 4x) [/tex]
[tex] 20x - 15 = 81 + 12x [/tex]
Collect like terms
[tex] 20x - 12x = 81 + 15 [/tex]
[tex] 8x = 96 [/tex]
Divide both sides by 8
[tex] x = \frac{96}{8} [/tex]
[tex] x = 12 [/tex]
✅QT = 4x - 3

16x=176
Answer:
x = 11
Step-by-step explanation:
16x = 176 is the problem
You bring the 16 over the the other side.
The equation changed.
x = 176 ? 16. You don't no the operation.
If the other side is number + variable,
it equals to division cause division is
the reverse operation.
That means, the equation changes again!
x = 176/16 Its easier to reduce cause its a

176/16 reduced is 11

Identify a segment skew to AB using the figure
Answer:
EH
Step-by-step explanation:
Skew lines are lines that do not intersect (touch) or are parallel!
A line segment skew to AB is EF. Therefore, option EF is the correct answer.
We need to identify a segment skew to AB.
What are skew lines?Skew lines are a pair of lines that are non-intersecting, non-parallel, and non-coplanar. This implies that skew lines can never intersect and are not parallel to each other. For lines to exist in two dimensions or in the same plane, they can either be intersecting or parallel.
From the given figure, line EF is skew line to AB.
A line segment skew to AB is EF. Therefore, option EF is the correct answer.

Select the table that represents a linear function. (Graph them if necessary.)
Answer:
table B represents the linear equation which is:
[tex]y=-3x+11[/tex]
The graph of the linear function is also attached below.
Step-by-step explanation:
Given the table B values
x y
0 11
1 8
2 5
3 2
As the equation for the linear function
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
As the y-intercept can be obtained by setting x=0
From the table, it is clear that when the value of x=0, then the value of
y=11.
so (0, 11) is the y-intercept.
Also taking two points (0, 11) and (1, 8) to find the slope
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:11\right),\:\left(x_2,\:y_2\right)=\left(1,\:8\right)[/tex]
[tex]m=\frac{8-11}{1-0}[/tex]
[tex]m=-3[/tex]
so substituting the value m=-3 and the point (1, 8) in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-8=-3\left(x-1\right)[/tex]
[tex]y-8=-3x+3[/tex]
[tex]y=-3x+3+8[/tex]
[tex]y=-3x+11[/tex]
comparing the equation with the slope-intercept form of linear equation
[tex]y=mx+b[/tex]
[tex]y=-3x+11[/tex]
here
m=slope=-3b=y-intercept=11Therefore, table B represents the linear equation which is:

If g + 11 = 16, then evaluate 5g + 12
Answer:
37
Step-by-step explanation:
use inverse operations to solve ,
16 - 11 = g
g = 5
if g = 5 then , 5 times 5 is 25 , add 12 to 25 and get 37
*please name brainliest if you can :)
The value of the expression 5g + 12 is 37, when g equals 5.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Substitution in mathematics is when we replace some specific numerical values to variables according to our wants or given in the problem.
Given A equation g + 11 = 16.
g = 16 - 11.
g = 5.
Now, 5g + 12
= 5×5 + 12.
