The value of z₂ - z₁ is -7 -8√(8i). And the second option is correct.
What is the equation?The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here, given that two expressions,
[tex]z_1=9+9\sqrt{3i}\\z_2=2+\sqrt{3i}[/tex]
To find the z₂ - z₁:
So,
[tex]z_2-z_1\\\\=2+\sqrt{3i}-(9+9\sqrt{3i})\\\\=2+\sqrt{3i}-9-9\sqrt{3i}\\\\=-7-8\sqrt{8i}[/tex]
The value of the equation, z₂ - z₁ = -7 -8√(8i)
Hence, the second option z₂ - z₁ = -7 -8√(8i) is correct.

Karen earns $5 by delivering newspapers each week. She saves $3 and she spends the rest. How many weeks will it take her to save enough money to buy a $35 gift card? (Use the table to help you solve the problem; you will need to copy it onto a piece of paper...)
explain your answer down below.
Answers
Answer:
Step-by-step explanation:
There is not a table to look at.
But, if she saves $3 a week. 35/3= 11.6. It'll take her 11.6 or 12 weeks to save up $35.
Answer:
12 weeks
Step-by-step explanation:
She earns $5 each week, but she only saves $3. This would mean that she saves $3 a week and with a end goal of $35, it would take 11.6 weeks, which would round up to 12.
Hope this helps :)

Eighteen 2.5 gallon buckets are needed to fill a cistern with water. Find the constant of variation. Please help! Thank you!
Answers
Given:
Eighteen 2.5 gallon buckets are needed to fill a cistern with water.
To find:
The constant of variation.
Solution:
If y is directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
Where, k is constant of variation.
In the given problem, water in cistern (w) is directly proportional to number of buckets (n).
[tex]w\propto n[/tex]
[tex]w=2.5n[/tex] (Capacity of each bucket is 2.5 gallons)
Therefore, the constant of variation is 2.5.
Answer:
45

The quantites are inversely so that means you multiply the numbers. Like 18 * 2.5. That's how I got 45
If Alfonso does a job in 30 hours more than Zoe, and they can do the job together in 8 hours, how long would it take Zoe to do the job alone?
Answers
Answer:
Step-by-step explanation:
Let the time it will take Alfonso be x
Let the time it will take Zoe be y
If Alfonso does a job in 30 hours more than Zoe, then;
x = 30+y...... 1
Also if they can do the job together in 8 hours, then;
x+y = 8.... 2
Substitute 1 into 2;
x+y=8
30+y+y = 8
40+2y = 8
2y = -32
y = -16
Hence X = 30-16
X = 14
y = 30+14 = 44
hence it will take Alfonso about 44hours to do the work alone

The perimeter of a rectangle window is 226 cm. If the length of the window is 62 cm, what is its width?
Answers
Answer:
51 cm
Step-by-step explanation:
perimeter = 2 * length + 2 * width
226 = 2 * 62 + 2 * width
226 = 124 + 2 * width
226 - 124 = 2 * width
102 = 2 * width
102/2 = width

write the linear equation from the given information in slope intercept form (-1,3); slope=-3
Answers
Answer:
y = -3xStep-by-step explanation:
The standard expression of equation of a line in slope-intercept form is expressed as;
y = mx+c
m is the slope
c is the intercept
Given
slope m = -3
Point (x, y) = (-1, 3)
x = -1 and y = 3
Get the intercept
To get the intercept c, we will substitute the given values into the equation above to have;
y = mx+c
3 = -3(-1)+c
3 = 3 + c
c = 3-3
c = 0
Substitute m = -3 and c = 0 into the equation above;
y = mx+c
y = -3x+0
y = -3x
Hence the required linear equation is y = -3x
