From examining the graph in the "image attached", note that we have a "line" in linear format" ; and that has a "solid line" (as opposed to a "dashed line"); with a "shaded portion" toward one side.
The presence of a "solid line" indicates:
" ≥" {"greater than or equal to"} ; or,
" ≤ " {"less than or equal to"};
________________________________________________________
So we can narrow down our answer choices to:
________________________________________________________
[C]: " y ≤ x − 2 " ; and:
[D]: " y ≥ x − 2 " .
________________________________________________________
Note:
________________________________________________________
A "dashed line" would have narrowed our answers to Choices [A] & [B].
_______________________________________________________
Now, look at inequalities in choices [C] & [D].
Start with Choice: [C]: " y ≤ x − 2 " ;
Now, take the point in the graph: "(0, 0)" ; which is in the shaded portion.
That is; when "x = 0 ; y = 0" .
Does this hold true for the inequality provided for Choice [C]:
→ " y ≤ x − 2 " ?
→ Plug in "0" for "x" ; and "0" for "y" ; and see if the inequality holds true ;
→ " 0 ≤ 0 − 2 " ?
→ " 0 ≤ -2 " ?? No!
_________________________________________________________
As such, the correct answer is: Answer choice: [D]: " y ≥ x − 2 " .
_________________________________________________________
However, let us substitute: x = 0 ; y = 0 ; for the point: " (0, 0)" within the "shaded portion" of the graph; as done above ; but this time, use the inequality for "Choice: [D]: " y ≥ x − 2 " .
→ " 0 ≥ 0 − 2 " ? ;
→ " 0 ≥ -2 " ?? Yes!
________________________________________________________
The correct answer is: [D]: " y ≥ x − 2 " .

The value of the hypotenuse x is equal to 12 units.
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle, the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Use the Pythagorean theorem for this. (a^2+b^2=c^2)
a=9, b=12, c=x
The value of x will be calculated as,
a² + b² = c²
9²+12²=x²
81 + 144 = x²
225 = x²
x =15
Therefore, the measure of x is 15 units.

47/7 = 6 5/7
Hope this helps!!
After Colby used 3 2/7 buckets out of Anastasia's 10 buckets of mulch, Anastasia has 6 5/7 buckets left. The subtraction was performed by converting mixed numbers to improper fractions, performing the operation, and then converting back to a mixed number.
Anastasia had 10 buckets of mulch for her garden. After Colby used 3 2/7 buckets, we need to subtract that amount from the total to find out how many buckets are left. To subtract the mixed number, we can convert it into an improper fraction and then perform the subtraction.
First, convert 3 2/7 to an improper fraction:
3 2/7 = 3 x 7 + 2 which is 21/7 + 2/7 = 23/7.
Now subtract the improper fraction from the total number of buckets:
10 - 23/7
Change 10 to a fraction with a denominator of 7 to get 70/7.
Subtract the two fractions:
70/7 - 23/7 = (70 - 23) / 7 = 47/7.
Convert the improper fraction back to a mixed number:
47/7 = 6 5/7 (since 47 divided by 7 is 6 with a remainder of 5).
So, Anastasia has 6 5/7 buckets of mulch left.

let me know if i'm wrong
The distribution property is a property where you simplify an equation or expression by distributing a variable or number outside a set of parenthesis and multiply it inside the parenthesis. It can only be done if the variables inside the parenthesis cannot be further combined.
For example,
2(x + 4)
Since you can't combine the x and the 4 inside the parenthesis, you distribute the 2 into the parenthesis and multiply it by x and 4.
2*x + 2*4
Now, we can just simplify this:
2x + 8
2x + 8 would be the simplest form.

Find the area of the circle. Use 3.14 for π. Round to the nearest square foot.
Answers
1. First, find the radius. Since the radius is allows half of the diameter, then we divide the diameter by two. 50/2= 25
2. Next, we square the radius. 25^2= 625
3. After that we multiply 625 ft by pi(3.14).
625 times 3.14= 1962.5
4. The last step is to round the the answer to the nearest square foot. Since 5 is at the end, we round up to 1,963.
So the answer is 1,963 ft^2.
the string, that supports the stairs, makes an angle of 50° with the floor. It reaches 3.2 m up the wall. How far is the base od the stringer from the wall?
Answers
The best way to do these problems is to draw a picture. In this case, you would have a right triangle. I included a picture.
If we use the 54 degree angles as our angle of reference, we are dealing with the opposite side and adjacent side. This makes it a tangent ratio.
We can set up the equation:
tan 54 = 3.2/x
1.19 = 3.2/x Cross Multiply
1.19x = 3.2 Divide by 1.19
x = 2.69
The base of the stringer is 2.69 m from the wall.

We use trigonometry to find the distance from the base of the string to the wall. The cosine of an angle in a right triangle is defined as the adjacent side length divided by the hypotenuse length. You can plug the given values into the rearranged formula and solve it.
Explanation:The question is asking about the distance from the base of the string (the part that touches the floor) to the wall. This is a typical trigonometry problem. We know that the string forms an angle of 50° with the floor and that it stretches up to 3.2 m on the wall. Given these values, we can use the cosine function to find the distance between the base of the string and the wall.
The cosine of an angle in a right triangle is defined as the adjacent side length divided by the length of the hypotenuse. In our case, you can think of the 3.2 m wall height as the 'adjacent' and the string length as the 'hypotenuse'. So, we can rearrange this relationship to solve for the base, or 'hypotenuse', of the triangle:
Length of string (hypotenuse) = Adjacent side / cos(angle)
Plugging in the values we know:
Length of string = 3.2 m / cos(50°)
After that, you can plug the numbers into a calculator to find the value in meters of the distance from the base of the string to the wall.

Find the total cost for a $579 smartphone with 5% sales tax
Answers
Final cost: $550.05
Final answer:
To calculate the total cost including a 5% sales tax on a $579 smartphone, convert the tax rate to a decimal and multiply it by the price, then add the result to the original price. The total cost would be $607.95.
Explanation:
To find the total cost for a $579 smartphone with a 5% sales tax, you'll need to calculate the amount of sales tax and then add it to the original price of the smartphone. Here's how you would do that step by step:
Firstly, convert the sales tax from a percentage to a decimal by dividing by 100. For 5%, you would calculate 5 ÷ 100 = 0.05.
Next, calculate the sales tax by multiplying the original price by this decimal. You do this by calculating $579 × 0.05 = $28.95 in sales tax.
Finally, add the sales tax to the original price to find the total cost. Add the two amounts together to get $579 + $28.95 = $607.95.
So, the total cost of the smartphone including sales tax would be $607.95.

an observer on a cliff 1200 feet above sea level sights two ships due East. The angle of depression to the shops are 48° and 33°. What is the distance between the ships?
Answers
The problem involves using trigonometry, specifically the tangent function, to determine the distance between the two ships. By calculating the distance from the observer to each ship separately and finding the difference, we find the distance between the two ships to be approximately 814.61 feet.
Explanation:The problem at hand involves the use of trigonometry, specifically tangent of an angle in a right triangle. Since we are dealing with angles of depression, we must understand that these angles are taken from a horizontal line - in this case, the line of sight from the cliff's edge.
First, let's consider the observer and the further away ship using tangent as follows:
tangent of 33° = height/distance, thus distance to the further ship = height / tangent of 33° = 1200 / tan(33) approximately equals to 1809.54 feet.Similar steps for nearer ship with angle of 48 degrees:
tangent of 48° = height/distance, hence distance to the closer ship = height / tangent of 48° = 1200 / tan(48) approximately equals to 994.93 feet.Therefore, the distance between the ships is the difference between the two distances calculated above, which will be 1809.54 - 994.93 = 814.61 feet.

To determine the distance between the two ships, use the angles of depression and the observer's height above sea level to find the horizontal distances to each ship with trigonometry and subtract the smaller from the larger.
Explanation:To calculate the distance between two ships using their angles of depression from an observer's viewpoint atop a cliff, we can employ trigonometry. Let us denote the observer's vertical distance above sea level as height (h), which is 1200 feet in this case. The angles of depression to the first and second ship are 48° and 33° respectively.
We will use the tangent of these angles to find the horizontal distances (d1 and d2) from the base of the cliff to each ship:
Using the tangent of the angle of depression 48° to find distance to first ship (d1):tangent(48°) = opposite/adjacent or, h/d1
Thus, d1 = h / tangent(48°)Using the tangent of the angle of depression 33° to find distance to second ship (d2):
tangent(33°) = opposite/adjacent or, h/d2
Thus, d2 = h / tangent(33°)
After finding d1 and d2, we subtract the smaller distance from the larger to get the distance between the two ships:
Distance between ships = d2 - d1
Finally, we convert the answer from feet to the desired unit if necessary.

Answers
B. White: 50% Pink: 11% yellow: 32.5% green: 6%
I believe there is a small typo here, as the probability of pink should be 11.5%
based on the calculations below.
Explanation:
probability of each color=number of shells of this color/total number of shells
To get it in percentage form, we will then multiply the probability by 100
We have:
number of white shells = 500 shells
number of pink shells = 115 shells
number of yellow shells = 325 shells
number of green shells = 60 shells
total number of shells = 500 + 115 + 325 + 60 = 1000 shells
Now, we will get the probability of each color as follows:
probability of white shells = (500/1000) * 100 = 50%
probability of pink shells = (115/1000) * 100 = 11.5%
probability of yellow shells = (325/1000) * 100 = 32.5%
probability of green shells = (60/1000) * 100 = 6%
Hope this helps :)
