The value of y is less than or equal to 0 (y ≤ 0).
What is inequality?
In mathematics, inequalities describe the relationship between two values that are not equal. Equal means to be equal, not. The "not equal symbol (≠)" is typically used to indicate that two values are not equal. But different inequalities are used to compare the values to determine whether they are less than or greater than.
Given:
4y + 1/5 ≤ 4/5
We have to find the value of y.
Subtract 1/5 from both sides,
4y + 1/5 - 1/5 ≤ 4/5 - 1/5
4y ≤ 3/5
Multiply both sides by 1/4
4y x 1/4 ≤ 3/5 x 1/4
y ≤ 3/20
y ≤ 0.15
Hence, the value of y is less than or equal to 0 (y ≤ 0).

Step-by-step explanation:
Recall that
\( \cos(x + \pi) = \cos x \cos\pi - \sin x \sin\pi\)
and
\( \sin(x - \pi) = \sin x \cos \pi - \cos x \sin \pi\)
But we also know that
\( \cos \pi = - 1 \\ \sin \pi = 0 \: \: \: \: \)
so the above relations reduce to
\( \cos(x + \pi) = - \cos x \\ \sin(x - \pi) = - \sin x \)

cos 0 = 1
Since the point (0, 1) is on the graph, this graph is y = cos x, but that is not a choice, so this must be the graph of the sine function with a horizontal translation.
sin 0 = 0

To solve this, we simply need to find the value of n and then substitute it into the function.
Given that;f(n) = 1.5 + 0.5(n -1), find f(10 - 3). This becomes f(7)
Substitute 7 in place of nf(7) = 1.5 + 0.5(7 - 1)f(7)

(3y = 10)/3
Y = 3.333
Answer:
The answer is No Solution.
Step-by-step explanation:
We can't add the two systems, so let's look for x. We would need to multiple them by (-6) and 2, which are the numbers in front of x. One must be a negative.
(2x + 3y = 7) * (-6)
(6x + 9y = 6) * 2
_____________
(-12x) + (-18y) = -42
(12x + 18y = 12
Both the x and y cancel each other out, and we're only left with -42 and 12, which doesn't really solve for x.
You can check the answer by checking for y. So, this time, we'll multiply the equations by (-9) and 3, which are the numbers in front of y.
(2x + 3y = 7) * (-9)
(6x + 9y = 6) * 3
___________
(-18x) + (-27y) = -63
18x + 27y = 18
Both x and y cancel out, and we're left with -63 and 18.

Step-by-step explanation:
A is thrice as good as workman as B and therefore is able to finish a job in 60 days less than B. Working together, they can do it in
20.4 days
22.5 days
25.6 days
30.1 days
Answers
Let's assume that B can do the job alone in x days.
Then, according to the question, A can do the same job alone in (1/3)x days.
Also, we know that A takes 60 days less than B to finish the job, so:
(1/3)x = x - 60
Solving for x, we get:
x = 90
Therefore, B can do the job alone in 90 days and A can do the same job alone in (1/3) * 90 = 30 days.
To find out how long they take to finish the job together, we use the formula:
(AB)/ (A+B)
where AB is the product of their individual times and A+B is their combined time.
Plugging in the values, we get:
(30 * 90)/(30+90) = 22.5
Therefore, working together, they can finish the job in 22.5 days.

Step-by-step explanation:
Step 1: Determine the area of the left rectangle
We can tell that the total shape seems like two rectangles glued together. We can separate the left rectangle and determine the area of it and then determine the area of the right rectangle and combine them. Lets first solve the left rectangle.
\(A = l * w\)
\(A_{left\ rectangle} = 2\ in * 4\ in\)
\(A_{left\ rectangle} = 8\ in^2\)
Step 2: Determine the area of the right rectangle
\(A = l * w\)
\(A_{right\ rectangle} = 3\ in * 2\ in\)
\(A_{right\ rectangle} = 6\ in^2\)
Step 3: Determine the total area
\(A_{total}=A_{left\ rectangle} + A_{right\ rectangle}\)
\(A_{total} = 8\ in^2 + 6\ in^2\)

Is there a difference between shapes when plotting Uniform acceleration towards (+)directtion,Uniform acceleration towards (-)direction, Uniform deceleration towards (+) direction and Uniform deceleration towards (-) direction in displacement time graph
Answers
Yes, there is a difference in the shapes of the displacement-time graphs for uniform acceleration towards the positive direction, uniform acceleration towards the negative direction, uniform deceleration towards the positive direction, and uniform deceleration towards the negative direction.
Uniform acceleration towards the positive direction:
In this case, the object's velocity increases in the positive direction over time. The displacement-time graph will have a concave-upward shape, forming a curve that starts with a small slope and gradually becomes steeper as time progresses.
Uniform acceleration towards the negative direction:
Here, the object's velocity increases in the negative direction, meaning it accelerates in the opposite direction to its positive direction.
The displacement-time graph will have a concave-downward shape, forming a curve that starts with a steep slope and gradually becomes less steep as time progresses.
Uniform deceleration towards the positive direction:
In this scenario, the object's velocity decreases in the positive direction, but it still moves towards the positive direction.
The displacement-time graph will show a curve with a decreasing slope, forming a concave-downward shape, indicating that the object is slowing down.
Uniform deceleration towards the negative direction:
Here, the object's velocity decreases in the negative direction, opposing its initial direction.
The displacement-time graph will have a curve with a decreasing slope, forming a concave-upward shape, indicating that the object is slowing down but still moving in the negative direction.
In summary, the shapes of the displacement-time graphs differ based on the direction and type of acceleration (positive or negative) and whether the object is undergoing uniform acceleration or uniform deceleration. These differences can be observed through the concavity and slope of the graphs.

Here we have also know that X-axis is temperature measured in degrees Fahrenheit with a range from about 55 to 100 degrees and the value of Y-axis is the number of cans of soda sold with a range from about 165 to 195 cans.
While we take into consideration that a reasonable value of the correlation coefficient r for these data is 1.2.
Where as if the temperature were measured in degrees Celsius (C = 5/9 * (F - 32)), then the value of r would change accordingly.

Write 78 as a product of prime factors
Answers
Answer:
13 is a prime number, not divisible by any number greater than 1 or less than 13. So the prime factorisation of 78 is: 78 = 2 ⋅ 3 ⋅ 13 This can also be represented by a factor tree:
Step-by-step explanation:
Answer:
78 = 2 ⋅ 3 ⋅ 13
Step-by-step explanation:
78 ends with an even digit, so is divisible by 2 and we find: 78 = 2 ⋅ 39
39 ends with an odd digit, so is not divisible by 2 .
The digits of 39 add up to a multiple of 3 , namely 3 + 9 = 12 . So we can tell that 39 is divisible by 3 : 39 = 3 ⋅ 13
13 is a prime number, not divisible by any number greater than 1 or less than 13 .
So the prime factorization of
78 is:
78= 2 ⋅ 3 ⋅ 13

Point C is the midpoint of AB and point B is between points A and D. If AD = 15 and BD = 7, what is CD?
Answers
Considering that the points A, B, C, and D are on the same line.
We know that C is the midpoint between A and B.
And B is between A and D.
First, let's sketch the points to visualize their positions:
The total length of the line AD is 15 units. Point B divides this line into two segments, AB and BD, so that:
\(AD=AB+BD\)From this expression, you can calculate the measure of line segment AB:
\(\begin{gathered} AD=AB+BD \\ AB=AD-BD \\ AB=15-7 \\ AB=8 \end{gathered}\)Next, if point C is the midpoint of AB, it means that it separates this segment into two equal segments AC and CB. We can calculate the length of these segments by dividing AB by 2:
\(\begin{gathered} AC=CB=\frac{AB}{2} \\ AC=CB=\frac{8}{2} \\ AC=CB=4 \end{gathered}\)Now, what is left is to determine the length of the segment CD
Line segment CD is formed by the segments CB and BD, so that:
\(\begin{gathered} CD=CB+BD \\ CD=4+7 \\ CD=11 \end{gathered}\)Line segment CD has a length of 11 units.

Answers
Inability to sleep properly for weeks is a warning sign that someone needs the help of a mental health professional. Correct option is C.
Difficulty sleeping, or insomnia, can be a warning sign that someone needs the help of a mental health professional. Insomnia can be caused by a number of mental health conditions, such as anxiety, depression, or post-traumatic stress disorder (PTSD), as well as other factors such as stress, poor sleep habits, or physical health problems.
Feeling shy when asked to walk onstage and overeating to increase bodily strength may be signs of anxiety or other emotional or psychological issues, but they are not necessarily warning signs that someone needs the help of a mental health professional.
However, if these behaviors are causing significant distress or interfering with daily life, it may be a good idea to seek the help of a mental health professional.
