The complex numbers z1 and z2 are graphed. Which point represents z1 – z2?
Answer:
A EDGE 2020
Step-by-step explanation:
I got it wrong twice and it gave me the answer :)
The point represents z₁ - z₂ will be A. Then the correct option is A.
What is a complex number?The complex number is the combination of the real part and the imaginary part. Then the complex number is given as
⇒ a+bi
The complex numbers z₁ and z₂ are graphed.
The expression of z₁ and z₂ are given below.
z₁ = 4 – i
z₂ = –3 – 2i
Then the difference between z₁ and z₂ will be
z₁ - z₂ = (4 – i) – (–3 – 2i)
z₁ - z₂ = 4 – i + 3 + 2i)
z₁ - z₂ = 7 + i
Then the correct option is A.

RedLara's puppy weighs 3.5 pounds and will gain approximately 0.5 pounds per
month.
Monica's puppy weighs 2 pounds and will gain 1 pound per month.
After how many months will both puppies weigh the same amount?
3 months
We can use a systems of equations to find when the values will equal each other, with x equal to months
Lara's Puppy: 0.5x+3.5
Monica's Puppy: x+2
Now create an equation for these puppy's weights to equal each other, and solve:
0.5x+3.5=x+2
0.5x=1.5
x=3

Jenny is an architect and is working to find the side length of a room in a house plan she is
reviewing. She knows that she can find the side length from the area using the formula 8 =
A. She could also find the side length using the perimeter with the formula 9 = she wants to see
what the design would look like with an equal perimeter and area. She graphs the formulas and
hnds the intersection point. What does this intersection point tell her?
O Cannot be determined
The measure of the side length
The side length that creates an equal perimeter and area,
The total perimeter and area of the room
Answer: At first I though O but you would be able to use A because you are able to make that 9 = to that 8
Step-by-step explanation:
The intersection point tells her the side length that creates an equal perimeter and area.
What is perimeter?
A closed shape's perimeter is the sum of the lengths of its outside boundaries. The lengths of all the sides are added to determine the measurement.

Find the value of x
(8x-1) (4x+7)
Answer:
The value of x = 7
Step-by-step explanation:
Given the right triangle
Right angle = 90°α = (4x+7)°β = (8x-1)°We know that the sum of angles of a triangle is 180°.so
Right angle + α + β = 180°
90° + 4x+7 + 8x-1 = 180
Group like terms
[tex]4x+8x+90+7-1=180[/tex]
Add similar elements: :4x+8x=12x
[tex]12x+90+7-1=180[/tex]
[tex]12x+96=180[/tex]
[tex]12x=84[/tex]
Divide both sides by 12
[tex]\frac{12x}{12}=\frac{84}{12}[/tex]
[tex]x = 7[/tex]
Therefore, the value of x = 7
If a certain medicine cures 85% of the people who take it,what is the probability that, if 6 people take the medicine, exactly 4 will be cured?
Answer:
if 6 people take the medicine, around 5 people will get cured if the cure probability is 85%.
Step-by-step explanation:
Given that a certain medicine cures 85% of the people who take it.
As 6 people take the medicine, we need to determine how many will be cured.
As
85% = 85/100 = 0.85
All we need is to multiply 6 with 0.85.
i.e. 6 × 0.85 = 5 (Rounded to the nearest 1 or the Ones Place)
Thus, if 6 people take the medicine, around 5 people will get cured if the cure probability is 85%.

A department store buys 300 shirts for a total cost of $7,200 and sells them for $30 each. Find the percent markup.
Answer:
80%
Step-by-step explanation:
because 7200 / 300 equals 24 and 24 / 30 equals .8 so its 80% and if you want to check the answer you take 30 * .8 OR 80% and it gives you 24
The percent markup is 25%.
What is percent markup?Markup percentage is calculated by dividing the gross profit of a unit (its sales price minus it's cost to make or purchase for resale) by the cost of that unit.
Given that, A department store buys 300 shirts for a total cost of $7,200 and sells them for $30 each.
Cost of one shirt = 7200 / 300 = $24
And they sold at $30 each,
Percent markup = 30-24 / 24 × 100
= 25%
Hence, the percent markup is 25%.

In 8-11, Explain how to get the variable alone in each equation
8. 8y = 5.6
9. x ➗ 15.2 = 3
10. u ➗ 8.7 = 12
11. 31.4 = 3.14y
Step-by-step explanation:
8. You divide each side by 8
[tex] \frac{8y}{8} = \frac{5.6}{8} [/tex][tex]y = \frac{5.6}{8} [/tex]9. You multiply each side by 15.2
[tex]x = 3 \times 15.2[/tex]X=45.610. You multiply bith sides by 8. 7
[tex]u= 12 \times 8.7[/tex]11. You divide both sides by 3.14
[tex]3.14y = 31.4 \\ y = \frac{31.4}{3.14} \\ y = 10[/tex]Hope this helps, have a wonderful day
Solve for x:
2x - 14 = 3x + 6
Answer:
x = - 20Step-by-step explanation:
[tex]2x - 14 = 3x + 6[/tex]
Move 3x to the other side of the equation
[tex]2x - 3x - 14 = 6 \\ - x - 14 = 6[/tex]
Move -14 to the right side of the equation.
[tex] - x = 14 + 6 \\ - x = 20[/tex]
Multiply both sides by - 1
[tex] - ( - x) = - 20 \\ x = - 20[/tex]
We have the final answer as
x = - 20Hope this helps you
Answer: add 14 to both sides of the equation
2x-14=3x+6
2x-14+14=3x+6+14
Simplify
add the numbers
2x-14+14=3x+6+14
2x=3x+6+14
add the numbers
2x=3x+6+14
2x=3x+20
subtract 3x from both sides of the equation
2x=3x+20
2x-3x=3x+20-3x
simplify
Combine like terms
2x-3x=3x+20-3x
-x=3x+20-3x
Combine like terms
-x=3x+20-3x
-x=20
Divided both sides of the equation by the same term
-x=20
-x/-1=20-/-1
Simplify
Cancel terms that are in both the numerator and denominator
-x/-1=20/-1
x=20/-1
Divide the numbers
x=20/-1
x=-20
So the answer is x=-20
