Match each subtraction of complex numbers to its simplified difference.
Here are the complex numbers with their simplified differences
(7 -3i) - (6 - 4i) = 1 + i
(4 + 3i) - (6 +2i) = -2 - i
(4 + 5i) - (3 - 4i) = 1 + 9i
(5 + 4i) - (9 + i) = -4 + 3i
A complex number is when a real number and an imaginary number are added together
Complex numbers are usually in the form : a + bi
where a and b are real numbers and i is an imaginary number
An example of a complex number:
in this complex number : (7 -3i)
7 and 3 are real numbers while i is the imaginary number
How to simplify complex numbers
In order to simplify these set of complex numbers, remember that when there is a bracket in mathematics it signifies multiplication.
Here are the set of rules that guide multiplication :
1. When a negative value is multiplied by a positive value, the value becomes a negative value
For example, -1 x 1 = -1
2. When a positive value is multiplied by a positive value, the value remains a positive value
For example, 1 x 1 = 1
3. When a negative value is multiplied by a negative value, the value becomes a negative value
For example,-1 x -1 = 1
Solution to the questions:
Using the above information, the complex numbers can now be simplified
1. (7 -3i) - (6 - 4i)
this above equation becomes :
7 - 3i - 6 + 4i
add like terms together
7 - 6 - 3i + 4i = 1 + i
2. (4 + 3i) - (6 +2i)
this above equation becomes :
4 + 3i - 6 - 2i
add like terms together
4 - 6 +3i - 2i = -2 - i
3. (4 + 5i) - (3 - 4i)
this above equation becomes :
4 + 5i - 3 + 4i
add like terms together
4 - 3 + 5i + 4i = 1 + 9i
4. (5 + 4i) - (9 + i)
this above equation becomes :
5 + 4i -9 -i
add like terms together
5 -9 + 4i - i = -4 + 3i
In order to solve for complex numbers remember that a bracket in mathematics means that a multiplication operation should be carried out. Also, pay cognisance to the rules guiding the multiplication of negative and positive numbers

you really need help for typing numbers into your calculator ? because there is nothing else to do here.
we get 3 values of x and need to calculate the functional values based on the given expressions by using each given value for x.
the only thing that requires a bare minimum of intelligence is to find the fitting expression.
so, for g(1) and g(2) we need to use the middle one, and for g(3) the third one. uhhhh, very difficult ...
typing it in here is way more effort than doing it directly on the calculator or really in the head.
so, g(1) = (1-1)² - 2 = -2
g(2) = (2-1)² - 2 = 1 - 2 = -1
g(3) = 1/2 ×3 - 2 = 3/2 - 2 = 3/2 - 4/2 = -1/2
uhhhh, come in, you could have done that too. and way faster.

what is the value of f'(6) if the formula is f(x)=-8x-3
Explanation:
Applying the derivative to f gets us
f(x) = -8x - 3
f ' (x) = -8
The fact that f(x) being linear directly means that the derivative is simply the slope value. No matter what we replace x with, the result is always -8.
Answer:
f'(6) = -8
Step-by-step explanation:
f(x)=-8x-3
First find the derivative of the function
f'(x) = -8
This is a constant so when x=6 it will be -8
f'(6) = -8

Evaluate 3|x|+2x-1 when x = -5.
Answer:
4
Step-by-step explanation:
To start off, we are going to input our x value into our expression.
3|-5| + 2(-5) - 1
Next, we are going to find the absolute value (always positive) of -5 and multiply 2 and -5.
3(5) - 10 -1
Now, we will multiply 3 and 5.
15 - 10 -1
Finally, we are going to combine our like terms (15, -10, and -1)
4
So! Our final answer for this expression is 4!

Convert 37.5% to a fraction. (Reduce your answer to lowest terms.)
Answer:
3/8
Step-by-step explanation:
The value of 37.5% reduced to the lowest terms is 15/40.
What is a fraction?A fraction is written in the form p/q, where q ≠ 0. Fractions are of two types they are proper fractions and improper fractions. Fractions can also be converted into percentages by multiplying them by 100.
We know e can convert percentages into decimals and fractions by dividing the percentage value by hundred.
Given we have to convert 37.5% as a fraction which is,
= 37.5/100.
= 375/1000.

show that the line x-y+2=0 and the line joining the points (4,6) and (10,12) are parallel to each other
x-y+2=0
-y= -x-2
y=x+2
In order for the other line to be parallel, the slope has to be the same.
(12-6)/(10-4)= 6/6= 1
Both slopes are the same, meaning it is parallel.
What is the range of the function f(x) = 3x + 2 overthe interval -6 < x < 5?
Answer:
(-16, 17)
Step-by-step explanation:
The range of the function will be (-16, 17)
The range of function f(x) = 3x + 2 overthe interval -6 < x < 5 is (-13,14)
What is Range?The difference between the highest and lowest values.
The given function is f(x) = 3x + 2
f(x) equal tp three times of x plus two.
The given interval is minus six less than x less than five.
-6 < x < 5
Which means the x values are -5, -4, -3, -2, -1, 0, 1, 2,3,4
Plus in the function
f(-5)=-15+2=-13
f(-4)=-10
f(-3)=-9+2=-7
f(-2)=-6+2=-4
f(-1)=-3+2=-1
f(0)=0+2=2
f(1)=3+2=5
f(2)=6+2=8
f(3)=9+2=11
f(4)=12+2=14
Hence the range of function f(x) = 3x + 2 overthe interval -6 < x < 5 is (-13,14)

Select the next item in the sequence.
10.172,10.983,10.994...
A. 10.972
B. 11.000
C.11.172
D.11.983
9514 1404 393
Answer:
B. 11.000
Step-by-step explanation:
The function looks like a reflected and translated exponential function with a horizontal asymptote near y = 11.000. The rate of change is decreasing so fast that the next value is expected to be very near 10.994. The closest one among the answer choices is 11.000.
_____
First differences are 0.811 and 0.011. The latter is about 0.0136 times the former. At that rate of change, we expect the next first difference to be about 0.000149, which would make the next number in sequence be about 10.9941—very little change from 10.994.
Clearly, first differences are not constant, so the function is not linear. Ratios of the numbers are not constant, so this is not an exponential (geometric) sequence. A reflected exponential function of the type described is a good fit.
With only 3 points given, the rule is not at all obvious. The next term could legitimately be anything you like, and a rule could be made that would fit it.

A campus deli serves 101 customers over its busy lunch period from 11:30 am to 1:30 pm. A quick count of the number of customers waiting in line and being served by the sandwich makers shows that an average of 18 customers are in process at any point in time. What is the average amount of time (in minute) that a customer spends in process?
Answer:
21.38 minutes
Step-by-step explanation:
the total number served = 101
teh number of hours that is spent in serving from 11.30 to 1.30 = 2 hours
Lq = average number of those that are in line = 18 customers
from here we are to find the flow rate
= [tex]\frac{total served}{service hour}[/tex]
= 101/2 = 50.5
the average time in waiting =
Lq/flow rate
= 18/50.5
= 0.3564 hours
convert to minutes = 0.3564 * 60 minutes
= 21.38 minutes
