Well, there can be three different steps.
Rearrange the equation so "y" is on the left and everything else on the right.
Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).

Factor X^2-y^2 using snowflake method
Answer:
(x+y)(x-y)
This is just the difference of squares.
The expression [tex]X^2 - y^2[/tex] can be factored using the difference of squares rule, resulting in the Factoring form [tex](X - y)(X + y)[/tex].
The equation you're asking about, [tex]X^2 - y^2[/tex], is an example of a difference of squares, a key concept in algebra. In general, the formula [tex]a² - b²[/tex] can be factored into [tex](a - b) (a + b)[/tex]. So for the expression [tex]X^2 - y^2[/tex], we can apply this rule to factor it into [tex](X - y)(X + y)[/tex].
Here is a step-by-step explanation:

K/6 = 15/18
Solve the proportion
Answer:
k = 5
Step-by-step explanation:
Step 1: Cross multiply
k/6 = 15/18
k(18) = 6(15)
18k = 90
Step 2: Divide both sides by 18
18k / 18 = 90 / 18
k = 5
Answer: k = 5
Another way to do it is to multiply both sides by 6
k/6 * 6 = 15/18 * 6
k = 90 / 18
k = 5
Answer: 5
Step-by-step explanation: To solve for k in the given proportion, we use the means-extremes property. The product of the extremes, (k)(18), equals the product of the means, (6)(15).
So we have (k)(18) or 18k = (6)(15) or 90.
Now we have the equation 18k = 90.
Dividing both sides by 18, k = 5.
It's a good idea to check the answer in these types of problems so if we plug a 5 back in for k in the original proportion, we have [tex]\frac{(5)}{6}= \frac{15}{18}[/tex] which is a true statement since 15/18 reduces to 5/6.
Add 3 to x subtract the result from 1 then double what you have

Subtract this from 1: [tex]1-(3+x)=1-3-x=-2-x[/tex]
Double this: [tex]2(-2-x)=-4-2x[/tex]
The required answer is 4 + 2x.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
The given expression is,
Add 3 to x subtract the result from 1 then double
Convert it to the numerical expression,
Add 3 to x = 3 + x
subtract the result from 1 = 3 + x - 1
⇒ subtract the result from 1 = 2 + x
Now double of result = 2(2 + x)
⇒ double of result = 4 + 2x
this is the required solution.
Thus, the required answer is 4 + 2x.

how do you find the perimeter of an equilateral triangle when given area
Step-by-step explanation:
To find perimeter, you need to add all the sides of the shape.
The area of a traingle is 1/2 bh.
You must find the "b" in order to find the perimeter.
Example:
A triangle has an area of 18 cm^2.
Therefore, the triangle has a 6 cm base and 6 cm height.
Then multiply the base by three to get 18 cm. That is your perimeter.
1. Mrs. Brown had $16 dollars in her
wallet. After shopping at the store, she
now has $8. How much money did
Mrs. Brown spend at the store?
Final answer:
Mrs. Brown spent $8 at the store, which is found by subtracting her remaining amount of $8 from her initial amount of $16.
Explanation:
The amount of money Mrs. Brown spent at the store can be calculated by subtracting the amount she had after shopping from the amount she had before going to the store. Mrs. Brown had $16 before shopping and was left with $8 after shopping. Therefore, to calculate how much money she spent, we would perform the following subtraction:
$16 (before shopping) - $8 (after shopping) = $8 (spent)
Hence, Mrs. Brown spent $8 at the store.

width = 12.1
equation : P = 4w + 4.6
Answer:
The width of the rectangle is 12.1 meters
Step-by-step explanation:
Step 1: Find the width
2w + 2(w + 2.3) = 53
2w + 2w + 4.6 = 53
Step 2: Combine like terms
2w + 2w + 4.6 = 53
4w + 4.6 = 53
Step 3: Subtract 4.6 from both sides
4w + 4.6 - 4.6 = 53 - 4.6
4w = 48.4
Step 4: Divide both sides by 4
4w / 4 = 48.4 / 4
w = 12.1
Answer: The width of the rectangle is 12.1 meters

The price of a video game increases by 20%, then decreases by 10%. If the final price is $46.98,
what was the original price?
Answer:
The original price was $43.50
Step-by-step explanation:
Let
x ----> the original price of a video game
we know that
1) The price of a video game increases by 20%
so
[tex]100\%+20\%=120\%=120/100=1.20[/tex]
The final price is equal to the original price multiplied by 1.20
so
[tex]1.20x[/tex]
2) The price of a video game decreases by 10%
so
[tex]100\%-10\%=90\%=90/100=0.90[/tex]
The final price is equal to the price at this moment multiplied by 0.90
so
[tex]0.90(1.20x)=1.08x[/tex]
we have that
[tex]1.08x=46.98[/tex]
solve for x
[tex]x=46.98/1.08\\x=\$43.50[/tex]

melissa looks around at a school assembly. she notices her younger sister directly to her right and her older brother 12 meters directly ahead of her if melissa's brother and sister are 13 meters apart how far apart are melissa and her younger sister?
Answer:
It was actually 8
Step-by-step explanation:
I don't actually know why it's 8, I just got it wrong on ixl. So yeah, it's 8
Melissa and her younger sister are 5 meters apart.
Explanation:In this scenario, Melissa's younger sister is directly to her right and her older brother is 12 meters directly ahead of her. Since her brother and sister are 13 meters apart, we can use the Pythagorean theorem to find the distance between Melissa and her younger sister.
Let's call the distance between Melissa and her younger sister 'x'. We can set up a right triangle with Melissa, her brother, and her sister as the vertices.
Using the Pythagorean theorem, we have:
x^2 + 12^2 = 13^2
Simplifying the equation, we get:
x^2 + 144 = 169
x^2 = 169 - 144
x^2 = 25
Taking the square root of both sides, we find:
x = 5
Therefore, Melissa and her younger sister are 5 meters apart.

How do u find the density of a sphere
Answer:
Step-by-step explanation:
The formula to find density of a sphere is mass/volume.
Density in simple words means the relation between weight and size of a substance. It is basically related to the compactness of a substance.It is a very useful characteristic and every material has density.
To calculate density, we must calculate the mass and volume of the substance.
p=m/v
where p= density, m= mass of substance, v= volume of substance
Formula to calculate the volume of a sphere = 4/3 [tex]\pi r^{3} \\[/tex]

To calculate the area of the park not occupied by the pond, first compute the total area of the park as (6x + 2)(3x + 7). Then subtract the area of the square pond, 64 sq. ft, to get the final expression for the unoccupied park area: (6x + 2)(3x + 7) - 64.
Explanation:The subject of this question is Algebra, specifically forming an expression for the area of a rectangle and subtracting the area of a square. First, calculate the total area of the rectangular park. The area of a rectangle is given by the product of its length and width. So, the total area of the park is (6x + 2)(3x + 7).
Second, find the area of the turtle pond. Since it's a square with a side length of 8ft, its area is 8*8 = 64 sq. ft.
Finally, to find the area of the park that is not occupied by the turtle pond, subtract the area of the pond from the total park area. So, the final expression is (6x + 2)(3x + 7) - 64.
