Answer:
-12 - 10i
Step-by-step explanation:
We are subtracting 3 + 2i from -9 - 8i. Rewrite the left side as -3 - 2i and then ADD this result to -9 - 8i:
-9 - 8i
-3 -2i
-----------
-12 - 10i
Answer:
-9-8i)-(3+2i)
= -9-8i-3-2i
Separate i and the numbers
= (-9-3)+(-8i-2i)
= -12-10i

Hope This Helps :)
Answer:
No
Step-by-step explanation:
No, this is not a function beacuse - 4 and 8 both have the same image 10 and a function is a relation in which every element has one image but this condition doesn't satisfy the definition. So, it is not a function.

Determine whether the equation below has a one solutions, no solutions, or
an infinite number of solutions. Afterwards, determine two values of x that
support your conclusion.
HELP PLEASE
Answer/Step-by-step explanation:
The equation, [tex] \frac{20}{x} = -5 [/tex] has one solution, x.
The value of x that will make the equation true, that is the number we can substitute for x into the equation that will make what we have on our left side equal to what we have on our right side is -4.
Substitute -4 for x in the equation and simplify:
[tex] \frac{20}{-4} = -5 [/tex].
Simplifying the equation:
[tex] -5 = -5 [/tex] (this is true).
A value of x that can make the equation false is 4.
Thus, replace x with 4, then simplify.
[tex] \frac{20}{x} = -5 [/tex]
[tex] \frac{20}{4} = -5 [/tex]
[tex] 5 = -5 [/tex] (false. 5 ≠ -5)
Simplify 12+5 (4x-6)
PLEASE HELP I HAVE 20 POINTS The mass of the Eiffel Tower is about 9.16 ⋅ 10^6 kilograms. The mass of the Golden Gate Bridge is 8.05 ⋅ 10^8 kilograms. Approximately how many more kilograms is the mass of the Golden Gate Bridge than the mass of the Eiffel Tower? Show your work and write your answer in scientific notation. (10 points)
Step-by-step explanation:
8.05 * 10^8 - 9.16 * 10^6
= 10^6 * (8.05 * 10^2 - 9.16)
= 10^6 * (805 - 9.16)
= 10^6 * (795.84)
= 10^8 * 7.9584
Therefore the answer in scientific notation is 7.9584 * 10^8.

factorise ax + ay + 3bx + 3by
Factor like terms..
(ax + ay) + (3bx + 3by)
= a(x + y) + 3b(x + y)
Finally, group the common factors of x + y and collect the terms to get:
(x + y )(a + 3b)
The factors of the given expression are (x + y ) and (a + 3b).
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
We have been given that expression as :
ax + ay + 3bx + 3by
We have to factorize the given expression.
⇒ ax + ay + 3bx + 3by
Factor like terms.
⇒ (ax + ay) + (3bx + 3by)
⇒ a(x + y) + 3b(x + y)
Take out the common factors of x + y and combine the terms to get:
⇒ (x + y )(a + 3b)
Therefore, the factors of the given expression are (x + y ) and (a + 3b).

Step-by-step explanation:
The property of equality is demonstrated moving from step a to step b is linear.
What is a linear equation?The linear equation is defined as the equation having a degree of one or the power of the variable will be one. The linear equation is represented by y = mx + c. Here y is the variable, m is the slope and, c is the intercept.
Given that b = 3, and m = 5, and y = mx + b then, b. y = 5x + 3. The equation can be formed as below:-
y = mx + c
y = 5x + 3
Therefore, the property of equality is demonstrated moving from step a to step b is linear.

Lcm of 4 and 15?
least common multiple
=================================================
Explanation:
Multiply the two values to get 4*15 = 60
Then divide by the GCF 1 to get 60/1 = 60. The GCF being 1 means the result hasn't changed.

Another example would be: "Find the LCM of 6 and 8". We would first do 6*8 = 48, then divide by the GCF 2 to get 48/2 = 24. The LCM of 6 and 8 is 24.

A total of 360 people were surveyed. Of the people surveyed, 70 said they were an early bird and preferred tea. The percentage of people surveyed who are night owls is ___%. The percentage of early birds who prefer to drink tea is ___%.
Answer:
A total of
360
people were surveyed. Of the people surveyed,
70
said they were an early bird and preferred tea. The percentage of people surveyed who are night owls is
60
%. The percentage of early birds who prefer to drink tea is
49
%.
Step-by-step explanation:
The last row and the last column give the total number of people surveyed, which is 360.
The joint frequency of the Early Bird column and the Tea row show that 70 people said they were an early bird and preferred tea.
To get the percentage of night owls, divide the total number of night owls by the total number of people surveyed and multiply by 100:
To get the percentage of early bird tea drinkers, divide the joint frequency of early birds and tea by the marginal total number of early birds and multiply by 100:
From total of 360 people surveyed, 70 people are early birds and preferred tea. Hence night owls is 60% and people who prefer to drink tea is 49%
What is a survey?A survey is a method of data collection and can be in the form of questionnaires and interviews. The survey tells us about the demands and needs of the people.
As per the question, the last row and column give us a total of 360. Those who are early birds and take tea are 70% of the population. To get the percentage we need to X night owls by the number of people surveyed multiplied by 100.
For the early bird tea, the total frequency of early birds by the marginal total number of early birds multiplied by 100.

Function h is a transformation of the parent exponential function, f(x)=2^x. h(x)=-3*2^x Which statement is true?
A. Function h is a vertical translation of function f. B. Function h is a reflection and a dilation of function f. C. Function h is a reflection and a translation of function f. D. Function h is a horizontal translation of function f.
Answer:
Function is a reflection and dilation of function f.
Step-by-step explanation:
A reflection gives the mirror image of function.
A function can be reflected about an axis by multiplying by -1.
To reflect function about the x-axis, multiply f(x) by -1 to get -f(x).
The correct option is: B. Function h is a reflection and a dilation of function f.
-----------------------
The functions are:
[tex]f(x) = 2^x[/tex]
[tex]g(x) = -3 \times 2^x[/tex]
It can be seed that g is f multiplied by -3.
The multiplication by a constant means that a dilation happened.Since the constant is negative, it means that a reflection also happened.In the image at the end of this question, it can be seen that the g, the blue graph, is a reflected and dilated version of f, the red graph.
Thus, the correct answer is:
B. Function h is a reflection and a dilation of function f.

1. Select all drawings in which a corresponding height h for a given base b is correctly identified
Answer:
A, B, D, F
Step-by-step explanation:
To determine which of the drawings are well labelled according to their corresponding height (h) for a given base, recall the following:
1. Base of a triangle could be any of the 3 sides of a triangke.
2. Height of a triangle is the perpendicular distance from the corner opposite the base to the base.
3. The height of a triangle could be indicated from outside the triangle.
Going by this 3 criteria, therefore, the following drawings can be said to be well labelled and correctly identifies by their corresponding height with respect to their bases:
A, B, D, F
11. Higher Order Thinking Using what you know
about angle pairs formed by parallel lines and a
transversal, how are 21, 22, 23, and 24 related
in the trapezoid? Explain.
3
Answer:
m∠1 + m∠3 = m∠2 + m∠4
Step-by-step explanation:
In the figure attached,
In the given trapezoid if two sides AB and CD are parallel and AD is a transverse,
m∠1 + m∠3 = 180°
Similarly, if AB and CD are parallel and BC is a transverse,
m∠2 + m∠4 = 180°
Therefore, m∠1 + m∠3 = m∠2 + m∠4 is the relation between these angles.

y = 4 - ax / 6
ax + 6y = 24
ax - ax + 6y = 24 -ax
