Answer:
8+2i
Step-by-step explanation:
Combine like terms
3+5=8
4i-2i=2i
Answer: 8 + 2i
Step-by-step explanation:
1) Rewrite the two complex numbers in standard form: (3 + 4i) + (5 − 2i) = 3 + 5 + 4i - 2i = 3 + 5 + 2i
2) Add the real parts and the imaginary parts separately: Real parts: 3 + 5 = 8 Imaginary parts: 2i + (-2i) = 0
3) Put the results in standard form: 8 + 0i = 8 + 0i = 8 + 0i = 8 + 0i = 8 + 0i = 8 + 2i

Diego buys 4.25 pounds of mushrooms. Each pound costs $2.99. Which expression gives the best estimate of the cost of the mushrooms?
(4)($2)
(4)($3)
(5)($2)
(5)($3)
Answer:
(4)($3)
Step-by-step explanation:
Given parameters:
Quantity of mushroom bought = 4.25pounds
Cost of each mushroom = $2.99
Unknown:
Best estimate for the cost of the mushroom = ?
Solution:
The cost of the mushroom is:
Total cost = quantity of mushroom bought x cost of each mushroom
Total cost = 4.25 x 2.99
You can round 4.25 to 4 and 2.99 to 3
Or 4 x 3 = $12
Answer:

which step could be used to help isolate the variable in the following equation 5.6j-0.12=4+1.1j
Answer:
Step-by-step explanation:
You did not ask for the answer so I will just tell you the steps. First, you have to add 0.12 on both sides. Then you are going to subtract 1.1j from both sides. Finally you are going to divide both sides by 5.6 to get your final answer.
Answer:
Subtract 1.1j from both sides.

Solve the equations. 3(x+6)−13=17. X=(). What is X?
Answer:
x=4
Step-by-step explanation:
distribute first 3x+18-13=17
combine like terms 3x+5=17
subtract 5 from both sides 3x=12
divide 3 from both sides x=4
Find the value of ‘x’ if 32 x 2^ x = 2^ 8
please give steps
Answer:
x = 3
Step-by-step explanation:
32 * 2^x = 2^8
32 * 2^x = 256
divide 32 from both sides
2^x = 8
then solve for x
2^3 = 8
For the complex number z = 12 + i, what is Modifying above z with bar?
12 – i
12 + i
–12 – i
–12 + i
Answer:
its A (12-i)
Step-by-step explanation:
got it right on edge 2020
The complex number with modifying bar will be 12 - i so option (A) will be correct.
What is a complex number?Complex numbers are helpful in finding the square root of negative numbers.
A complex number is the sum of a real number and an imaginary number.
The general form of a complex number is a + ib where the first part a called real and the ib is called imaginary.
If we solve x² + 1 = 0 ⇒ x = √(-1) which is called as iota(i).
Bar of complex number = replace i (iota) with - i (iota)
since z = 12 + i
So,
z bar = 12 - i
So 12 - i will be the correct answer to the given question.

Maribelle uses x yards of material to make a quilt. A customer requests 5 quilts that are 20% larger than the normal pattern. Write an expression to represent the total yards of material needed for the requested quilts in two different ways?
Answer:
i. 5(x + 0.2x) yards
ii. 6x yards
Step-by-step explanation:
Since the requested quilts are 20% larger than the normal pattern, then;
20% of x = 0.2 x
Thus,the yards of material to make each of the requested quilts increased by 0.2x yards.
So that;
To make one of the requested quilt, the yards required = x + 0.2x
For 5 requested quilts, the total yards required = 5(x + 0.2x)
Total yards of material for the requested quilts is 5(x + 0.2x).
Also,
5(x + 0.2x) = 5x + 5(0.2x)
= 5x + x
= 6x
Thus, the total yards required is 5(x + 0.2x) or 6x.
Graph the linear equation y = 2
Answer: Please look at the steps to see the answers.
Step-by-step explanation:
The line y= 2 has a slope of 0 meaning that for any input of x the results will always be 2.
This means the the graph will be a horizontal line through the point, (0,2)

Write the equation of the line that passes through the points (4,-6) and (-2,3)
Here is your answer and an explanation
Answer: y = -2/3x
Explanation:
This can be determined by calculating the gradient of the straight line, using:
m=ΔyΔx
=−6−34−(−2)
=−96
=−32
Then we use the slope-point form of the straight line:
y−y1=m(x−x1)
to give:
y−3=−32(x−(−2))
∴y−3=−32(x+2)
∴y−3=−32x−3
∴y=−32x
